IVF for premature ovarian failure: first reported births using oocytes donated from a twin sister.
ABSTRACT Premature ovarian failure (POF) remains a clinically challenging entity because in vitro fertilisation (IVF) with donor oocytes is currently the only treatment known to be effective.
A 33 year-old nulligravid patient with a normal karyotype was diagnosed with POF; she had a history of failed fertility treatments and had an elevated serum FSH (42 mIU/ml). Oocytes donated by her dizygotic twin sister were used for IVF. The donor had already completed a successful pregnancy herself and subsequently produced a total of 10 oocytes after a combined FSH/LH superovulation regime. These eggs were fertilised with sperm from the recipient's husband via intracytoplasmic injection and two fresh embryos were transferred to the recipient on day three.
A healthy twin pregnancy resulted from IVF; two boys were delivered by caesarean section at 39 weeks' gestation. Additionally, four embryos were cryopreserved for the recipient's future use. The sister-donor achieved another natural pregnancy six months after oocyte retrieval, resulting in a healthy singleton delivery.
POF is believed to affect approximately 1% of reproductive age females, and POF patients with a sister who can be an oocyte donor for IVF are rare. Most such IVF patients will conceive from treatment using oocytes from an anonymous oocyte donor. This is the first report of births following sister-donor oocyte IVF in Ireland. Indeed, while sister-donor IVF has been successfully undertaken by IVF units elsewhere, this is the only known case where oocyte donation involved twin sisters. As with all types of donor gamete therapy, pre-treatment counselling is important in the circumstance of sister oocyte donation.

ABSTRACT: For the gamete and embryo donation community, it is well recognized that the implementation of a gamete and embryo donor registry (GEDR) represents a good initiative to ensure the best possible health conditions for donor-conceived individuals. Be they national, institutional or independent, GEDR can play a major role in the transmission of health-related genetic and medical information. However, from a bioethical analysis standpoint, GEDR raise many questions regarding the extent of their beneficent nature. Based on the recent Canadian GEDR aborted attempt, this article will focus on bioethical issues and paradoxes that can impact the wellbeing of donor-conceived individuals, half-siblings, donors and parents. On one hand, the implementation of a GEDR can be ethically justified as a beneficent action towards lessening harm associated with the transmission of hereditary disease and increasing the effectiveness of preventive and therapeutic approaches. On the other hand, examined through the concept of nonpaternalistic beneficence, GEDR challenge us to recognize beneficiaries’ free agency, as well as offer reliable and pertinent information. Ultimately, beyond an individualistic application of the principle of beneficence, socioethics invite us to consider consistency with societal values as a prerequisite for achieving a common good. Because the issue of whether or not to protect the donor’s anonymity occupies the forefront of the discussion surrounding gamete and embryo donation, there is less interest in other initiatives, which may be implemented to ensure the best possible medical and psychosocial conditions for donor-conceived individuals. In this article, we propose a bioethical analysis of the use of gamete and embryo donor registries (GEDR) from the angle of the principle of beneficence. More specifically, we will concentrate on the Canadian situation regarding GEDR. We will look at the strengths and pitfalls of such a mechanism and suggest a solution to maximize the benefits of a GEDR. Many have suggested that such an initiative could have a beneficial impact on the wellbeing of donor-conceived individuals, half-siblings, donors and parents, by ensuring the constant flow of health-related medical and genetic information. As self-evident as the social acceptability of a GEDR may seem, we wish to show the limitations of the benefits that such a registry is supposed to provide. We argue that a GEDR has to do more than simply transmit health-related information between parties. It also has to be based on pertinent and reliable data, be useful for health promotion and recognize beneficiaries’ free agency. Ultimately, the implementation of a GEDR has to take into consideration wider social values.Reproductive biomedicine online 01/2013; · 2.98 Impact Factor

ABSTRACT: Apparent rise in the incidence of infertility in females and the trend shifting towards delayed child bearing brought up the concept of ovarian ageing. Women in their early thirties show poor ovarian reserve which is an entity named as early ovarian ageing. Early ovarian ageing is mostly genetically determined, but acquired modifiable factors like smoking, or ovarian surgery have some roles. Infertility and subfertility are the only clinical recognizable sequelae in the early ovarian ageing. The worrisome fact is that the outcome of assisted reproductive techniques is also not that much encouraging. Even if ovarian priming with DHEA has raised hope in the assisted reproductive techniques for these patients, but more randomized trials are needed to support this. Screening of these women with antimullerian hormone, antral follicle count and genetic analysis may be useful for recommendation at appropriate biological time regarding conception or fertility preservation.Journal of reproduction & infertility. 01/2013; 14(1):3-7.

Background: Premature ovarian failure (POF) remains a clinically challenging entity because in vitro fertilisation (IVF)
with donor oocytes is currently the only treatment known to be effective.
Methods: A 33 year-old nulligravid patient with a normal karyotype was diagnosed with POF; she had a history of
failed fertility treatments and had an elevated serum FSH (42 mIU/ml). Oocytes donated by her dizygotic twin sister
were used for IVF. The donor had already completed a successful pregnancy herself and subsequently produced a total
of 10 oocytes after a combined FSH/LH superovulation regime. These eggs were fertilised with sperm from the
recipient's husband via intracytoplasmic injection and two fresh embryos were transferred to the recipient on day
Results: A healthy twin pregnancy resulted from IVF; two boys were delivered by caesarean section at 39 weeks'
gestation. Additionally, four embryos were cryopreserved for the recipient's future use. The sister-donor achieved
another natural pregnancy six months after oocyte retrieval, resulting in a healthy singleton delivery.
Conclusion: POF is believed to affect approximately 1% of reproductive age females, and POF patients with a sister
who can be an oocyte donor for IVF are rare. Most such IVF patients will conceive from treatment using oocytes from
an anonymous oocyte donor. This is the first report of births following sister-donor oocyte IVF in Ireland. Indeed, while
sister-donor IVF has been successfully undertaken by IVF units elsewhere, this is the only known case where oocyte
donation involved twin sisters. As with all types of donor gamete therapy, pre-treatment counselling is important in the
circumstance of sister oocyte donation.
Patient age and number of prior failed fertility treatments
have trended upward in recent years, and both factors
have an adverse impact on pregnancy rates with IVF.
Among women presenting for fertility treatment, those
with premature ovarian failure (POF) comprise an impor-
tant subset as about 1% of all women will have this diag-
nosis . Because POF is characterised by early loss of
normal ovarian function before age 40, the unrecoverable
loss of oocytes results in a bleak fertility prognosis unless
oocyte donation with IVF is used.
Contemporary research has identified some genetic
causes of POF, implicating a close association with Fragile
× syndrome  and mutations in the inhibin alpha sub-
unit gene . Fragile × mental retardation-1 (FMR1) con-
tains an unstable sequence of CGG trinucleotide repeats
in its promoter region, with expansions of >200 trinucle-
otide repeats typically leading to abnormal methylation
and silencing of FMR1 expression . Therefore, in
monozygotic (identical) twin sisters, any genomic anom-
aly linked to POF would be expected to negatively affect
reproductive outcome in both siblings. The present
report describes successful IVF for a POF patient where
donated oocytes were obtained from her dizygotic (non-
identical) twin sister.
Methods and Results
A 33 year-old nulligravida presented with her husband
for reproductive endocrinology evaluation. The couple
had been attempting to achieve a pregnancy for 2 1/2
years. They had undergone two unsuccessful IVF cycles
and a diagnosis of premature ovarian failure had been
made after the second attempt. Neither partner smoked
and both were in good general health. All screening labo-
ratory tests were normal for husband and wife, however

her serum FSH was elevated at 42 mIU/ml. Her karyo-
type was 46,XX. Intrauterine contours assessed via saline
infusion sonogram were normal. The husband's semen
analysis at our centre identified mild asthenozoospermia
but was otherwise normal. Considerable patient counsel-
ling had already occurred after the two previous failed
IVF treatments, and the couple understood that further
cycles of IVF using native oocytes would probably be
futile. However, the wife had a sister who had volunteered
to serve as a known oocyte donor.
This sister (donor) was the dizygotic twin of the patient
(recipient). She was married, had previously conceived
without medical assistance and had a 10-month old child.
The sister did not smoke, had a normal menstrual pattern
and had discontinued breastfeeding four months before
assessment. Her cycle day three FSH was 8.8 mIU/ml; all
infectious disease and hormonal screening tests were
normal. Additional counselling was undertaken for both
couples (together and separately) in advance of the
planned treatment and written informed consent was
obtained from all parties . Supplementary genetic test-
ing for recipient and donor were declined.
After pituitary down-regulation with GnRH-agonist,
the donor began a combined 225 IU/d FSH (Puregon®,
Organon [Ireland] Ltd, Swords) plus 75 IU/d LH (Luv-
eris®, Merck Serono Europe Ltd, London) superovulation
regime. She received 10,000 IU hCG via subcutaneous
injection on stimulation day eight with an uneventful
transvaginal ultrasound-guided oocyte retrieval 36 h
later. Ten oocytes were obtained and eight of these were
metaphase II. Following ICSI with fresh sperm obtained
from the recipient's husband, normal 2 pn fertilisation
was noted in seven embryos.
Parallel to this, an appropriate endometrial response in
the recipient was established by supplementary estrogen
administration and verified by serial transvaginal ultra-
sound assessments. On day three, two fresh embryos
were transferred to the recipient 11 mm inferior to the
uterine fundus under ultrasound guidance; four embryos
were cryopreserved the same day. Luteal support post-
transfer was administered as previously described .
Pregnancy was confirmed 13 days post-transfer by posi-
tive hCG test, with a twin intrauterine gestation identi-
fied on follow-up obstetrical sonogram at seven weeks.
The patient had an unremarkable obstetrical course.
Following a failed labour induction, she had a caesarean
delivery at 39 weeks' gestation resulting in the birth of
healthy male/male twins. Mother and babies were dis-
charged from hospital five days post-partum in good con-
dition; all continue to do well. Of note, an unassisted
pregnancy was achieved by the sister-donor within six
months of oocyte retrieval, which resulted in another sin-
gleton delivery of her own.
In the setting of the advanced reproductive technologies,
the difficult diagnosis of premature ovarian failure is
often followed by discussions about donor oocyte IVF.
This treatment modality has become an important com-
ponent of the comprehensive assisted fertility treatment
programme, and has been available in Ireland for several
years. Patient survey results from Irish patients have gen-
erally agreed with findings reported elsewhere, showing a
strong preference for sister-donor over anonymous-
donor oocyte approach in IVF . Although successful
sister-donor oocyte IVF has been available in Australia
 and USA  for several years, this is the first descrip-
tion of IVF births resulting from this technique in Ire-
land. Indeed, because all prior births reported from sister
oocyte donors involved a non-twin sibling as the gamete
source, the current case appears to be the first in the
medical literature validating a specific role for twin sister
oocyte donation in IVF. Although IVF incorporating
oocytes donated from a twin sister does not usually differ
from ordinary (non-twin) sister oocyte donation, this
case does extend the range of therapeutic options in POF
to include a dizygotic twin as the oocyte source.
Although most POF cases probably result from de novo
mutations , the genetics of this disorder are complex
and have not yet been fully elucidated. Accordingly, any
POF patient who contemplates sister oocyte donation
should be advised about the possibility that any oocytes
donated by a sister might carry a POF mutation [11,12].
Anonymous donor oocyte IVF is generally regarded as
having a better reproductive outcome than IVF involving
a related oocyte donor , and special ethical consider-
ations exist with sibling gamete donation that do not
apply in anonymous oocyte donation. Perhaps the most
important of these is awareness of the resultant family
dynamic following a birth of a child conceived from sis-
ter-donor oocyte IVF . While counselling fully devel-
oped these issues, our patient nevertheless regarded the
proven fertility of her (dizygotic) twin sister as sufficiently
reassuring to proceed safely in the absence of genetic
data. In this case satisfactory psychological assessments
were completed, no absolute contraindication to known
oocyte donation IVF was present, and ongoing counsel-
ling resources were available throughout the IVF
It must be acknowledged that few POF patients will
have a sister willing and able to serve as a known oocyte
donor for IVF. Accordingly, for most POF patients repro-
ductive success will be achieved clinically from IVF using
oocytes from an anonymous oocyte donor. But against
the background of "routine" donor oocyte therapy for
POF, the current report describes an IVF approach for
the exceptional case where a dizygotic twin oocyte donor
