Sperm donor anonymity: a concept rendered obsolete by modern technology

The use of donor sperm began as a medical practice with a level of secrecy bordering on shame. In the United States, donor sperm insemination was first performed by Dr. William Pancoast in 1884 at Thomas Jefferson Medical College in Philadelphia. The patient was never told, and it is unclear whether the husband was completely informed as to exactly what was occurring. This was done to prevent “irreparable harm” to the resultant Continue reading…

Prevalence of ‘obesity-associated gonadal dysfunction’ in severely obese men and women and its resolution after bariatric surgery: a systematic review and meta-analysis

BACKGROUND Sexual dimorphism manifests noticeably in obesity-associated gonadal dysfunction. In women, obesity is associated with androgen excess disorders, mostly the polycystic ovary syndrome (PCOS), whereas androgen deficiency is frequently present in obese men in what has been termed as male obesity-associated secondary hypogonadism (MOSH). Obesity-associated gonadal dysfunction, consisting of PCOS in women and MOSH in men, is a frequent finding in patients with severe obesity and it may be ameliorated Continue reading…

Altered levels of mitochondrial DNA are associated with female age, aneuploidy, and provide an independent measure of embryonic implantation potential.

Older women tend to generate blastocyst-stage embryos with elevated levels of mitochondrial DNA, which is associated with aneuploidy and poor implantation, according to a new a new study of embryos derived from IVF clinics. The findings suggest that clinical tests to assess mitochondrial DNA levels could effectively help screen for “good” embryos during in vitro Continue reading…

Family History is Underestimated in Children with Isolated Hypospadias: A French Multicenter Report of 88 Families

Purpose While familial forms of complex disorders/differences of sex development have been widely reported, data regarding isolated hypospadias are sparse and a family history is thought to be less frequent. We aimed to determine the frequency of hypospadias in families of boys with hypospadias, to establish whether these familial forms exhibit a particular phenotype and Continue reading…

Prevalence of Post-Micturition Incontinence before and after Anterior Urethroplasty

Purpose In this study we aimed to define the prevalence of preoperative and postoperative post-micturition incontinence or post-void dribbling after anterior urethroplasty for urethral stricture disease. We also sought to determine risk factors for its presence. Materials and Methods We retrospectively reviewed a prospectively maintained, multi-institutional urethral stricture database to evaluate post-micturition incontinence using a Continue reading…

Multi-Institutional Outcomes of Endoscopic Management of Stricture Recurrence after Bulbar Urethroplasty

Purpose Approximately 10% to 20% of patients will have a recurrence after urethroplasty. Initial management of these recurrences is often by urethral dilation or direct vision internal urethrotomy. In the current study we describe the outcomes of endoscopic management of stricture recurrence after bulbar urethroplasty. Materials and Methods We retrospectively reviewed bulbar urethroplasty data from Continue reading…
