Introduction: Across many cultures, penis size has been associated with virility, and concerns about penile length are commonplace. Peyronie's disease (PD) is a known acquired cause of penile shortening. Objectives: This paper describes the psychosocial impacts of penile length on men and their partners, both generally and in men with PD, and ev...
Article
Introduction Renal function is often estimated using validated study equations and serum creatinine (Cr) as a filtration marker. Contemporary studies suggest that cystatin C may be used as a more accurate alternative to Cr, as it avoids limitations related to diet and muscle mass that affect Cr and predispose to an overdiagnosis of chronic kidney d...

Introduction Recent studies have investigated the use of finasteride in the management of alopecia and benign prostatic hyperplasia (BPH). Finding suggest significant increased reporting odds ratios (ROR) of suicidality and psychological adverse events in patients younger than 45. As alopecia and BPH are side effects of testosterone therapy, we sou...
Article
Introduction Testosterone has long been thought of as the male sexual hormone. Individuals with elevated levels of testosterone have been portrayed to have increased sexual promiscuity. It is not unimaginable that these theories would become prevalent at the opposite end of the spectrum and demonstrable with muted sexual practices seen with lower l...

Materials and methods: This phase 4 study included men who received CCH in either 12-month, double-blind, placebo-contro...
Article
Introduction: Urologists use ultrasound in the male infertility workup to evaluate scrotal contents and objectively identify varicoceles if their presence is questionable on physical examination. We assessed practice patterns and diagnostic criteria of male reproductive urologists using ultrasound to evaluate varicoceles. Methods: An anonymous o...
Article
Ejaculatory duct obstruction is an uncommon but surgically correctable cause of male infertility. With the advent and increased use of high-resolution transrectal ultrasonography, anomalies of the ejaculatory ducts related to infertility have been well documented. Although there are no pathognomonic findings associated with ejaculatory duct obstruc...

This monograph, written by the pioneers of IVF and reproductive medicine, celebrates the history, achievements, and medical advancements made over the last 40 years in this rapidly growing field.
Article
As assisted reproductive technologies use increases, the evaluation of male factor infertility has often become overlooked. However, male evaluation remains critically important, with benefits seen in overall health, as well as in natural and assisted pregnancy and birth rates. A comprehensive assessment of the male partner should be offered to all...
Article
Vasectomy is the method of contraception chosen by more than 500,000 American men annually, and by upwards of 8% of married couples worldwide. However, following the procedure, nearly 20% of men express the desire for children in the future, and approximately 2-6% of American men will ultimately undergo vasectomy reversal (VR). VR is a complex micr...
Article
Hypogonadism and its therapies have a significant impact on male fertility potential. It is necessary to determine the etiology to treat and counsel the patient appropriately on therapeutic options. For the hypogonadal male on exogenous testosterone, management should begin with cessation of the exogenous testosterone and supplemental subcutaneous...
Article
To investigate the association between hypogonadal symptoms and free testosterone (FT) levels in men with near-normal total testosterone (T) levels (250-350 ng/dL) and to determine whether a discriminatory threshold for FT exists below which hypogonadal symptoms become more prevalent. We reviewed the charts of 3167 men who presented to an outpatien...
Article
Objectives To examine the efficacy of intralesional collagenase clostridium histolyticum (CCH) in defined subgroups of subjects with Peyronie's disease (PD).Subjects and Methods The efficacy of CCH compared with placebo from baseline to week 52 was examined in subgroups of subjects from the Investigation for Maximal Peyronie's Reduction Efficacy an...
Article
In humans, recent studies have correlated anogenital distance (AGD) in adult men to testicular function. While studies of a group of men suggest an association, the utility of AGD in an infertility evaluation remains uncertain. We sought to determine the utility of AGD to predict male fertility. Between 2010 and 2011, men were recruited at a urolog...

Introduction: Varicoceles are a common cause of male infertility; repair can be accomplished using either surgical or radiological means. We compare the cost-effectiveness of the gold standard, the microsurgical varicocele repair (MV), to the options of a nonmicrosurgical approach (NMV) and percutaneous embolization (PE) to manage varicocele-assoc...

... Goldstein et al collected and analyzed 5-year outcome information from patients previously enrolled in IMPRESS I and II, as well as two additional open-label studies. 49 They found an additional 9% decrease in curvature as well as a decreased PDQ bother score, five years after initial treatment. 8 Although subsequent study designs have varied, multiple studies have demonstrated an improvement in the degree of curvature ranging from 13° to 23°. ...
... The classic treatment for ejaculatory duct obstruction is transurethral resection of ejaculatory ducts (6,7). Although the therapeutic effect of this surgical method has been proven, it is more traumatic and more likely to have postoperative complications. ...

... 50 In the era of assisted reproductive technology (ART), remarkable energy is invested in improving embryo quality and pregnancy success, but the merit of proper male evaluation and pre-treatment strategies is overlooked as ICSI can provide the couple with a baby without the need to explain the nature of underlying male infertility. 44,[51][52][53] However, the notion that SDF could impair reproductive outcomes has prompted the use of SDF testing in clinical settings, 54 albeit controversies still exist on the utility of SDF as a biomarker for male infertility. 38,55 Moreover, given the association of SDF and potentially remediable conditions, medical interventions have been explored as a means of improving sperm DNA integrity, with the ultimate goals of enhancing fertility and increasing the likelihood of achieving healthy offspring. ...
... Background Every year more than seven million couples seek treatment for infertility, a disease that affects around 15% of couples worldwide [1]. Unsuccessful clinical pregnancy after 12 months of regular sexual intercourse is considered infertility [2,3]. ...
... Sperm extraction and cryopreservation at the time of vasectomy reversal should be discussed preoperatively. It should be offered as an option for patients who want to avoid a future sperm extraction in the event of persistent oligospermia or azoospermia following reversal [32]. Vasectomy reversal is accomplished by one of two techniques: vasovasostomy (VV) or vasoepididymostomy (VE). ...
... In a recent systematic review and meta--analysis, Kirby et al. concluded that men with varicocele who undergo surgical repair present increased odds of achieving pregnancy and live birth when compared to those who do not (37). In a comment to that article, Hockenberry and Lipshultz added that this finding demonstrates there is essentially a mis-sed opportunity in diagnosing and treating varicocele (38). Indeed, the findings of our study further support the need for a formal urological evaluation and, if needed, intervention, not only with the intent of increasing pregnancy and live birth rates, but in decreasing the potential promutagenic effects of oxidative DNA damage, such as discussed above. ...

... Therefore, testosterone may be a treatment option for most patients with DED (Sullivan et al., 2002;Supalaset et al., 2019). However, testosterone can cause severe systemic side effects and the US FDA issued a warning that testosterone might increase the risks of heart attack and stroke (Seftel, 2015;Ohlander et al., 2016). Further based on a systematic review of clinical studies of applying androgen in the treatment of DED, the administration of testosterone through an ocular drug delivery system (ODDS) can be a favorable option for DED with minimal systemic side effects (Wang & Deng, 2020). ...
... However, there is some conflicting evidence regarding the predictive ability of free testosterone. Ramasamy et al. performed a chart review of over 3000 men attending an outpatient men's health clinic and did not find any association of hypogonadal symptoms with free testosterone among men with near-normal TT [53]. Despite the lack of a clear trend in the associations and predictive ability of total versus free testosterone, evidence from Asian populations does appear to be consistent in identifying that free testosterone, but not total testosterone, has a significant inverse association with age [4, 21, 22] ; this is also consistent with the present study. ...
