One size does not fit all: variations by ethnicity in demographic characteristics of men seeking fertility treatment across North America.

Objective: To compare racial differences in male fertility history and treatment.

Design: Retrospective review of prospectively collected data.

Setting: North American reproductive urology centers.

The vasal fluid proteomic profile and microscopic sperm presence at time of vasectomy reversal.

Background: The microscopic characteristics of vasal fluid at time of vasectomy reversal (VR) guide operative decision making and predict fertility outcomes. The proteomic profile of this vasal fluid has not been described or correlated with the microscopic fluid appearance. To characterize the vasal fluid proteome at time of VR and evaluate the variation of the vasal fluid proteome with respect to microscopic presence of sperm.

Reproductive endocrinologists are the gatekeepers for male infertility care in North America: results of a North American survey on the referral patterns and characteristics of men presenting to male infertility specialists for infertility investigations.

Objective: To characterize the referral patterns and characteristics of men presenting for infertility evaluation using data obtained from the Andrology Research Consortium.

Design: Standardized male infertility questionnaire.

Setting: Male infertility centers.

Reconsidering vasectomy reversal over assisted reproduction in older couples.

Objective: To provide pregnancy and live birth rates from a contemporary series of vasectomy reversals in men with female partners aged ≥35 years and to correlate the results with IVF.

Setting: Tertiary academic referral center.

Design: Retrospective comparative study of prospectively collected database.

Evaluation of Vasectomy Trends in the United States.

Objective: To use the Truven Health MarketScan database to better approximate the annual rate of vasectomies performed in the US population, to determine changes over time, regional differences, providers performing this, and to know if there is any monthly variation in vasectomy rates.

Materials And Methods: Claims data were evaluated from 2007 to 2015 to determine the annual prevalence of vasectomy by patient age and region in the United States. The cohort included men aged 18-64 years with at least 1 claim in any given year in Truven Health MarketScan.

Factors and practice patterns that affect the decision for vasoepididymostomy.

Introduction: To determine the factors used to make the decision between vasovasostomy (VV) and vasoepididymostomy (VE) by leaders performing microsurgical vasectomy reversal using a questionnaire.

Materials And Methods: An online questionnaire was sent to all members of the Society for the Study of Male Reproduction (SSMR), a male reproduction subspecialty society of the AUA, using the SurveyMonkey platform.

Results: Sixty-seven surgeons responded to the questionnaire (27% of SSMR members).

Vasectomy Reversal for Postvasectomy Pain Syndrome: A Study and Literature Review.

Objective: To review our institution's experience and success with vasectomy reversal to treat postvasectomy pain syndrome (PVPS) over the last 20 years.

Materials And Methods: A single surgeon (E.F.

Impact on Pregnancy of Gross and Microscopic Vasal Fluid during Vasectomy Reversal.

Purpose: We compared fertility outcomes with gross and microscopic fluid findings at vasectomy reversal at a high volume vasectomy reversal center.

Materials And Methods: A retrospective study of a prospective database was performed. All vasectomy reversals were performed by a single surgeon (EFF) between 1978 and 2011.

Higher outcomes of vasectomy reversal in men with the same female partner as before vasectomy.

Purpose: We reviewed fertility outcomes of vasectomy reversal at a high surgical volume center in men with the same female partner as before vasectomy.

Materials And Methods: We retrospectively studied a prospective database. All vasectomy reversals were performed by a single surgeon (EFF).

The laboratory diagnosis of testosterone deficiency.

The evaluation and treatment of hypogonadal men has become an important part of urologic practice. Fatigue, loss of libido, and erectile dysfunction are commonly reported, but nonspecific symptoms and laboratory verification of low testosterone (T) are an important part of evaluation in addition to a detailed history and physical examination. Significant intraindividual fluctuations in serum T levels, biologic variation of T action on end organs, the wide range of T levels in human serum samples, and technical limitations of currently available assays have led to poor reliability of T measurements in the clinical laboratory setting.

Relating economic conditions to vasectomy and vasectomy reversal frequencies: a multi-institutional study.

Purpose: It was theorized that the use of permanent contraceptive methods may vary with economic conditions. We evaluated the relationship between vasectomy/vasectomy reversal frequencies at several large referral centers and national economic indicators during 2 recessions spanning 2001 to 2011.

Materials And Methods: We performed an institutional review board approved, retrospective chart review to identify the number of vasectomies/vasectomy reversals per month at several large referral centers from January 2001 to July 2011.

The current role of endourologic management of renal transplantation complications.

Introduction. Complications following renal transplantation include ureteral obstruction, urinary leak and fistula, urinary retention, urolithiasis, and vesicoureteral reflux. These complications have traditionally been managed with open surgical correction, but minimally invasive techniques are being utilized frequently.

Herniorrhaphy with polypropylene mesh causing inguinal vasal obstruction: a preventable cause of obstructive azoospermia.

Objective: To report a multiinstitutional experience of men presenting with infertility secondary to inguinal hernia repair using polypropylene mesh.

Summary Background Data: An estimated 80% of inguinal hernia operations involve placement of a knitted polypropylene mesh to form a "tension-free" herniorrhaphy. The prosthetic mesh induces a chronic foreign-body fibroblastic response creating scar tissue that imparts strength to the floor and leads to fewer recurrences.

Vasectomy reversal performed 15 years or more after vasectomy: correlation of pregnancy outcome with partner age and with pregnancy results of in vitro fertilization with intracytoplasmic sperm injection.

Objective: To document a contemporary series of vasectomy reversals performed in men 15 years or more after vasectomy and to correlate the results with spousal age and results of ICSI for obstructive azoospermia.

Setting: University referral center for male infertility.

Design: Retrospective analysis of a single surgeon's experience compared with reported ICSI results.
