Abstract
Male infertility can range from neurohormonal imbalances, reproductive tissue disruptions, qualitative and quantitative deterioration of semen to sexual behavioral
problems. e global deterioration of male reproductive health is a major concern and the modern therapeutic approaches to combat male infertility are expensive,
less accessible, have long term treatment tenure and possess various side eects. Whereas, the herbal therapies, are better positioned to oer more holistic approaches
to improve male reproductive health. In Ayurvedic pharmacology, there exists a special group of herbs, classied as vajikarana or aphrodisiacs, which nourishes and
stimulates the sexual tissues. is review concentrates on the Ayurvedic approach to ameliorate male reproductive health referring to some of the most important
scientically tested herbs which have been reported to accentuate male fertility by imposing either stimulating or nourishing eects on the male reproductive organs.

Introduction
Organisms strive to exist and preserve own genetic characteristics
through subsequent progenies owing to their reproductive potencies.
In this aspect, human being is one of the most successful survivors
on earth. But the present scenario is alarming, as besides female
reproductive complications and dysfunctions, male reproductive
health is suering a deteriorating trend throughout the globe [1-
6]. Sexual dysfunction, an earnest medical issue marring social and
biological relationships, occurs in 25%-63% of women and 10%-52%
in men. Sexual dysfunction in men can be explained as the failure to
accomplish normal sexual intercourse, inability to respond to erectile
stimuli or sustain an erection, retarded ejaculation, decreased libido,
unregulated sexual behavior etc. [7]. Innumerable synthetic products
are abundantly oating in the global market with quick remedial
claims. But most of them are associated with suppressing symptoms
and side eects [8]. ereby people are again oriented back to herbal
and ayurvedic aphrodisiacs having the holistic approach to cure male
reproductive problems from the root of the causes.
Aphrodisiacs, agents to arouse sexual desire and performance, when
derived from herbs, have been observed to directly been able to excite
male sexual libido, contribute to sustenance of reproductive activities,
restore healthy tissue functioning and also aid the neuroendocrine
regulation for exhibiting required sexual strength with content state of
mind and body [9]. is review, with the aim to highlight the healthy long-
term remedy of male sexual problems, concentrates on the scientically
tested herbs which have been reported to accentuate male fertility.
Overview of male reproductive disruptions
Standard clinical and laboratory evaluations are not enough to
nd out the causes behind most of the male infertility cases [10]. It
can range from hormonal or neuronal imbalances, reproductive tissue
disruptions to qualitative and quantitative deterioration of semen.
Oxidative stress induced by reactive oxygen species (ROS) is a major
causative factor in male infertility [11,12]. e mature spermatozoa
are encased in polyunsaturated lipid membrane which is vulnerable to
the oxidative damage induced by ROS, and this, in turn, can impair
spermatogenesis and reduce sperm quality, motility and morphology
[10,14]. e regulation of hypothalamic-pituitary-gonadal (HPG)
axis is the main controller of male reproductive function where the
hypothalamus produces gonadotropin-releasing hormone (GnRH)
to stimulate the secretion of follicle-stimulating hormone (FSH) and
luteinizing hormone (LH) from the anterior pituitary. e secreted FSH
and LH act on the Sertoli cells and Leydig cells, respectively to stimulate
spermatogenesis and testosterone [11,14,15]. Spermatogenesis is
regulated by well-maintained crosstalk of FSH, LH, intratesticular
testosterone and other hormones. ereby, HPG axis disruptions are
detrimental to semen parameters [16,17].
Reproductive endocrinologist opts for injectable medications
including recombinant FSH, human menopausal gonadotropin (hMG),
human chorionic gonadotropin (hCG) and gonadotropin-releasing
hormone (GnRH) to treat men with abnormal semen parameters. An
oral medication, Clomiphene citrate which is an estrogen receptor
antagonist, is also given to the patient in order stimulate gonadotropin
release from the pituitary. But these options are expensive, less
accessible, having long term treatment tenure and possess various side-
eects [18]. Whereas, the herbal therapies, are better positioned to oer
more holistic approaches to improve male reproductive health.

Herbal therapy and male reproductive health
According to the Ayurvedic concept, health depends upon balance
between three fundamental bodily bio-elements or doshas referred to as
Vata, Pitta and Kapha [19]
Vāt a or Vat a (airy element), characterised by dry, cold, light,
minute, and movement.
Pitta (ery element) or bile, owing through the liver and
permeating the overall heating of the body.
Kapha (watery element) is characterised by heaviness, cold,
tenderness, slowness, lubrication, nutrient carrier, nourishment.
In Ayurvedic pharmacology, there exists a special group belonging
to rasayana herbs, classied as vajikarana, that aid nourishment and
also stimulate the sexual tissues. Moreover, they also help to promote
beauty and sex appeal. Further classications of herbs that increase
spermatogenesis, are known as shukrala. With the knowledge of the
possible causes and factors leading to male infertility, the appropriate
herb can be selected to meet the need [19].
In Sanskrit ‘vaji’ and ‘karana’ mean ‘horse’ and ‘power’ respectively,
in order to convey the notion about the power or strength that a horse
possesses. ese are the herbs which can be referred to in Western
term as aphrodisiacs. Vajikarana herbs can be used as stimulants or
tonics to improve male reproductive vitality. Stimulants to reproductive
functions are typically heating substances like fenugreek, garlic,
damiana, and onion. ey have an invigorating action on the male
sexual organs. Tonics provide better nourishment to the reproductive
tissues to rejuvenate the quality and quantity of the same. Some herbs
have both stimulating as well as nourishing properties, such as garlic,
fenugreek, shilajit, and ashwagandha (Withania somnifera).
e Ayurvedic herbal drugs can be classied in varied ways, and
one such simplied classication according to their functions on male
reproductive health is as follows [20]:
Herbs increasing the quantity of semen or stimulating semen
production, for example, Polygonatum verticillatum, Mucuna pruriens,
Microstylis wallichii, Roscoea procera, and Asparagus racemosus.
Herbs purifying and improving semen quality, for example,
Vetiveria zizanioides, Saussurea lappa, Myrica nagi, Sesamum indicum,
and Anthocephalus cadamba.
Herbs rejuvenating ejaculatory functions, for example, Strychnos
nux vomica, Myristica fragrans, Cannabis sativa, and Cassia
occidentalis.
Herbs improving sustenance and ejaculatory performance, for
example, Cinnamomum tamala, Anacyclus pyrethrum, Sida cordifolia,
Asparagus racemosus, Mucuna pruriens, and Cannabis sativum.
Herbs increasing libido, namely, Asparagus racemosus, Withania
somnifera, Datura stramonium, Anacyclus pyrethrum, Hibiscus
abelmoschus, and Opium.
Some common Ayurvedic herbs to improve male
fertility
Ashwagandha (Withania somnifera)
In Sanskrit, ashwagandha refers to ‘the smell of a horse’, owing to its
root’s strong odor resembling that of horse urine. Another reason for its
naming for mythological comparison of the sexual vitality it may impart
to men with that of a horse. Innumerable benecial qualities to alleviate
male reproductive disorders including induction of spermatogenesis,
improved blood ow to the reproductive tissues and regulated
endocrine functions. It relieves conditions such as spermatorrhea,
nocturnal emission, premature ejaculation, and enlarged prostate.
Withania somnifera is able to combat stress-induced male infertility
and protects against swimming-induced endocrine dysfunctions of
male reproduction in rat [21]. e aqueous extract of this herb has been
shown to improve spermatogenesis, owing to elevated interstitial cell
stimulating hormone and testosterone-mimicking eects together with
induction of nitric oxide synthase [22]. Yet another study showed that
Ashwagandha root extract administration resulted in a signicantly
greater improvement in spermatogenic activity and increase in serum
hormone levels in the oligospermic patients as compared to the placebo
treated [23]. is herb evidently combats against oxidative stress
by reducing lipid peroxidation as well as protein carbonyl content,
increasing sperm count and motility, rejuvenating the seminal plasma
levels of antioxidant enzymes. Withania somnifera root powder when
administered to normozoospermic infertile man in a dosage of 5 g/
day for 3 months showed a signicant reduction in stress, improved
antioxidants, and enhanced semen volume and levels of vitamins A,
C, and E and also corrected fructose. is herb’s action at the HPG
axis level is also evident through various studies, one such showed
signicant increased serum testosterone and LH levels and decreased
levels of FSH and prolactin (PRL) in infertile men [24-26].
In terms of ayurvedic explanations, the grounding and deeply
nourishing qualities of Withania somnifera contribute for its being one
of the best vata appeasing medicines. Its warming energy provokes pitta
if used in excess and so it is recommended to combine it with cooling
vajikarana herbs such as licorice, vidari, shatavari, bala, while using as a
drug. Owing to it stress relieving, relaxing eect on the body and mind,
as well as fortifying of all the dhatus, it is considered as the best herb to
target many of the contributing factors that are associated with reduced
sexual energy.
Kapikacchu (Mucuna pruriens)
is sweet yet sometimes bitter tasted herb is quite heavy and oily.
Mucuna pruriens is mainly used to balance vata and pitta, as both
kapha and ama are increased in excess by this herb. Typical doses of the
powdered Mucuna pruriens range from 1.5 to 6 grams [27]. Alkaloids
derived from M. pruriens seeds were found to stimulate spermatogenesis
and overall weight of the testicles and accessory glands in the male
albino rat [28]. M. pruriens is capable of stimulating sexual activities
in male rats as inferred by increased mounting frequency, ejaculation
latency and also enhanced intromission frequency [29,30]. In a study,
M. pruriens has been shown to eciently recover the spermatogenic
loss which was induced in male rats by ethinyl estradiol administration
and the herb’s benecial eects were mediated by mitigation of ROS,
apoptosis regulation, and increase in the number of germ cells. e
major constituent of M. pruriens, L-D O PA, largely contributes to its
pro-spermatogenic properties [31]. e seed extract of M. pruriens
showed marked improvement in sexual potency and behavior, libido,
sperm parameters, and endocrine levels [32]. M. pruriens has been able
to ameliorate the levels lipids, triglycerides, cholesterol, phospholipids,
vitamin A, C, and E and corrected fructose nullifying oxidative stress
induced lipid peroxidation in seminal vesicles and restored the levels of
SOD, catalase, GSH, and ascorbic acid in seminal plasma [33, 34]. From
the neuroendocrine perspective, M. pruriens elevates testosterone, LH,
dopamine, adrenaline, as well as noradrenaline levels and decreased

levels of FSH and PRL in infertile men. M. pruriens treatment to
infertile men indeed improves steroidogenesis and semen quality [35].
Shatavari (Asparagus racemosus)
Shatavari can serve as a powerful male tonic. With a bittersweet
taste, this herb renders cooling and purifying eect to the liver and
blood, and targets pitta at its main site in the small intestine. Its cooling
properties balance the heating herbs which are used to improve sperm
count, such as, garlic, onion, ashwagandha, etc. us, Shatavari prevents
depletion of sperm caused by burning via excess pitta. Owing to its
heavy and nourishing properties, it is useful for vata, especially when
combined with heating vajikaranas like ashwagandha or bala. As a drug,
it can be prepared as a milk decoction with 3 to 6 grams of the herb,
or can be taken alone or in combination with other herbs [19]. Sexual
desires are associated with emotional aspects and in such conditions,
this herb in combination with cooling nervine herbs like brahmi (gotu
kola) may enhance libido and help to overcome agonizing emotions like
anger and irritability. Shatavari is thus one of best pitta pratyanika herbs
which can be associated in several Ayurvedic formulas to balance pitta
and vata in mediating male reproductive functions. General fatigue,
low sexual energy, anger, stress, irritability, inammation, hyperacidity,
urogenital infections, burning sensations etc. are the conditions when
this herb can be used as drug in standardized dosage of 2 to 6 grams of
the powdered herb, 2 to 3 times daily. is herb is avoided in cases of
respiratory or sinus congestion [19].
Bala (Sida cordifolia)
Bala refers to ‘strength’ in Sanskrit, and being a rejuvenative tonic
herb for vata and pitta, this herb nds application in nourishment and
strengthening of all the bodily tissues, especially the muscle, plasma,
muscle, bone marrow and reproductive tissue. It is sweet, heavy and
oily and increase kapha when used in excess, and also is mildly cooling.
Bala is one of the best anti-vata herbs in Ayurveda which mitigates
disorders related to both body and mind. It plays a leading role as an
Ayurvedic herb in the treatment of balakshaya or chronic fatigue, to
rejuvenate overall health in exhaustion of physical or mental strength.
It serves as a tonic to restore sexual strength, promote spermatogenesis
and enhance male fertility [19,20].
is herb can be taken internally or even used as massaging oil in
combination with Ashwagandha onto penis to improve its tone and also
to prevent premature ejaculation. Its combination with herbs such as
gokshura, ashwagandha, vidarikandha, saw palmetto, and kapikacchu,
proved to be benecial for prostate health. A typical dose of Bala ranges
from 2 to 6 grams, to be taken 2 to 3 times daily [19].
Vidarikandha (Ipomoea digitata)
Vidarikandha is a starchy tuber, eective in promoting
spermatogenesis with faster action when taken as a milk decoction.
It is lighter for kapha types than shatavari and bala. Its combination
with kapikacchu is eective in the treatment of enlarged prostate. is
sweet and cool herb promotes ojas, muscle tone, motor coordination
and nullies sexual debility associated with nervousness and adrenal
stress when used in formulation with ginseng, licorice, gokshura, and
ashwagandha. It falls right between too warming and too cooling herbs
providing great value as both a vata and pitta balancing herb. A typical
dose of Vidarikandha ranges from 2 to 6 grams, 2 to 3 times daily [19].
Shilajit (Asphaltum, mineral pitch)
Shilajit is immensely important Ayurvedic herb which, with its
heating energy, increases virility and sexual stamina via removing excess
kapha, while maintaining the normal genital tone. In kapha related
reproductive imbalances, it is used in combination with Ashwagandha.
For enlarged prostate, its combination with saw palmetto, punarnava,
gokshuradiguggulu, ashwagandha, or vidhari, are eective herbal
remedies. is herb should be used in doses ranging from 250 to 500
mg twice daily [19].
Pippali (Piper longum)
Pippali is a rejuvenating herb with a warming, stimulating and
kapha reducing action. Its oily nature prevents it from drying making
it suitable for vata and its pleasant post digestive eect makes it more
calming to pitta than other hot spices and herbs. It aids blood ow to
the reproductive tissues when taken in combination with Ashwagandha
[19,20].
According to the Ayurveda, Pippali enhances life energy and expels
impurities via respiration. It also improves digestion, absorption,
assimilation, respiration and reduces arthritic agonies. e typical
dosage of this herb is 1 to 3 parts in complex formulas, or ranges
from 250 mg to 1.5 grams. Pippali should be avoided in high pitta or
inammatory conditions [19].
Butea superba
Buteasuperba Roxb (Leguminosae) or the ‘Red KwaoKrua’, has long
been consumed as a stimulant of male sexual vigor. Its alcoholic extract
(0.01, 0.1 or 1.0 mg/kg BW/day) for 6 months signicantly elevted the
sperm concentration and enhanced sperm motility with no disruptive
signs to sperm or testis [36]. Powdered crude extract of this herb at the
doses of 2, 25, 250, and 1250 mg/kg body weight in male rats for 8 weeks
increased testis weight and sperm counts [37]. Moreover, the ethanol
extract of B. superba has been shown to increase penile erection acting
through cAMP/cGMP pathways [38].
Curculigo orchioides
Curculigo orchioides Gaertn (Amaryllidaceae), or Kali Musli or
Syah (black) Musli, is an aphrodisiac or rejuvenator ameliorating
sexual arousal and performance by inducing penile erection, mating
sustenance, orientation behavior, etc. is herb also promotes
anabolic and spermatogenic eect by pronounced increased weight of
reproductive organs. Rats that received Curculigo orchioides treatment
displayed reduction in mount latency, increment in penile erection index,
and increase in mount frequency and anity towards female [39,40].
Its lyophilized aqueous extracts are shown to improve the
pendiculatory activity in male rats aer as well as preserve the in vitro
sperm aer 30 min. of incubation [41]. e aqueous extract of the herb
is eective at a dose of 200 mg/kg. In case of physically induced or heat
induced sexual dysfunction, this herb is useful in ameliorating the
decreased spermatogenesis and mitigated disruptions owing to the heat
shock protein [42].
Cynomorium coccineum
Cynomorium coccineum Linn. (Cynomoraceae) is a black leaess
parasitic plant without chlorophyll. Aqueous extract of this herb has
been shown to induce signicant elevation in the sperm count, the
percentage of viable sperm and sperm motility, reduced the number of
abnormal sperm, increased spermatogenesis [43].
Chlorophytum borivilianum
Safed Musli (Chlorophytum borivilianum) of family Liliaceae is
claimed to be an eective aphrodisiac and sexual stimulant. Ethanolic

roots extract of this herb or sapogenins extracted from the roots showed
anabolic and spermatogenic eect in treated male rats evidenced by
total body weight increase and also increment in weight of reproductive
organs. e herb could also aect sexual behavior of animals by
reducing mount ejaculation, post-ejaculatory latency, and intromission
latency, increasing mount frequency and anity towards female [44].
Moreover, the aqueous extract of dried roots of this herb enhanced
sexual arousal, strength, and libido as well as sperm count in Wistar
male rats [45]. is herb also reportedly improves male reproductive
functions in diabetic scenario [46,47].
Epimedium koreanum
Epimedium L. (Berberidaceae), is a popular Chinese herb and
botanical supplement used as health tonic. Most important species
of this herb used for medicinal purposes are E. pubescensMaxim., E.
brevicornum Maxim, E. koreanumNakai, E. sagittatum (Sieb. EtZucc)
Maxim, and E. wushanense T.S. Ying [48]. Hydroalcholic extract of
the herb shown to display aphrodisiac eects and are commonly used
to enhance erectile function [49]. e primary active component
of Epimedium extracts, Icariin, is a type of avonoid and selectively
inhibits phosphodiesterase-5 (PDE5) improving erectile function
[50]. Icariin also can mimic the eects of testosterone inducing
spermatogenesis [51].
Eurycoma longifolia
Eurycoma longifolia Jack (Simaroubaceace) or Tongkat Ali, is one
of the major aphrodisiac herb from Malaysia [52]. E. longifolia extract
treatment showed successful induction of sexual motivation in naive
male rats [53]. Ethanol extract of this herb increased the sexual libido
and performance of the treated male rats by increasing the duration of
coitus and copulation frequency [54].
Tribulus terrestris
Tribulus terrestris Linn. (Zygophyllaceae) or puncture vine, a
perennial creeping herb, has worldwide distribution and is regarded
as an aphrodisiac since ancient times besides being used for various
ailments such as inammations, leucorrhoea, urinary infections, edema,
and ascites [55]. Administration of T. terrestris to animals showed to
improve plasma testosterone level and induced spermatogenesis [56]. It
also increases the levels of testosterone as well as luteinizing hormone
[57] and the activities of dehydroepiandrosterone, dihydrotestosterone,
and dehydroepiandrosteronesulphate [58]. e corpus cavernosal
tissues of New Zealand white rabbits following treatment with this
herb were tested in vitro with various pharmacological agents as well as
electrical eld stimulation and the herb was shown to have proerectile
eect [59]. It increases sexual behavior evident through increase in
mount frequency and intromission frequency, reduction in mount
latency, intromission latency, and penile erection index as well as
increase in prostate weight and intracavernosal pressure [60,61]. is
herb also possesses androgen, testosterone, dihydrotestosterone (DHT),
and Ddehydroepiandrosterone (DHEA) increasing property having
stimulating eects on reproductive functions and thus used in mild to
moderate cases of endocrine disruptions [62,63]. e ability of to induce
nitric oxide release may also account for its claims as an aphrodisiac [64].
Mechanism of action
Male reproductive functions are restored and controlled
by induction or inhibition of neurochemicals, regulation of
neuroendocrine axis and their cross talks as well as by local mediators
acting within the reproductive tissues [65-67]. e herbal therapies
may ameliorate male reproductive functions possibly at three levels. (1)
Herbs may act on the central or peripheral nervous system improving
the responsiveness of male reproductive tissues. e neuronal control
over the male reproductive organs is mediated by an orchestra of
neurochemicals/neurotransmitters, among which the serotonin and
dopamine are the prime controllers of sexual behavior with serotonin
mediating inhibitory functions and dopamine playing an excitatory role
[68]. (2) e eects of herbal therapies to regulate the level of the nitric
oxide support their contribution towards treating erectile dysfunctions.
Nitric oxide (NO) is an established endogenous mediator of penile
erection [64] and its synthesis via NO synthase is mainly concentrated
in structures of the brain that are involved in sexual behavior (olfactory
bulb, amygdala, septal structures, supraoptic and paraventricular
nuclei, etc.) [69,70]. NO is a known vasodilator which can increase
blood ow to the penis inducing penile erection and to other male
reproductive organs facilitating better hormonal accessibility in the
same to promote robust reproductive functioning [71]. (3) Herbs can
favourably interfere in the HPG axis in the regulation of sex hormones
importantly testosterone, LH, FSH and interstitial hormones as well as
their cross- talks which synchronise male reproductive functioning,
such as, the development of secondary male sexual organs, accentuate
pubertal changes and increase overall male fertility [72].
Conclusion
Vajikarana or aphrodisiac herbs can be used as stimulants or tonics
to improve male reproductive vitality. Stimulants to reproductive
functions are typically heating herbs having an invigorating action
on the male sexual organs. Herbal tonics provide better nourishment
to the reproductive tissues to rejuvenate the quality and quantity of
the same. Some herbs have both stimulating as well as nourishing
properties. Owing to the health complications, partial impact and high
cost of modern therapies for male infertility, the herbal aphrodisiacs
are regaining popularity and laying their long-term impact on
male reproductive health by improving sexual behavior, vigor,
neuroendocrine control as well as structural and functional aspects
of reproductive tissues, qualitative and quantitative improvement in
semen and also sperm morphology and motility. Biomedical research
should pierce deeper to emerge with more hidden mechanisms by
which innumerable herbs may act to eradicate male infertility which is
becoming a major threat to upcoming progenies.
