Testicular cancer disproportionally affects men of reproductive age making fertility an important aspect of testicular cancer survivorship. Men with testicular cancer have more semen parameter abnormalities and a higher incidence of infertility compared to the general population. All treatment options for testicular cancer negatively affect fertility with recovery rates varying by treatment.

Article Synopsis
  • - The study aimed to explore how aging, metabolic syndrome, daily rhythms, and seasonal changes affect serum testosterone levels based on current guidelines for testosterone deficiency.
  • - Using data from the UK Biobank and evaluating 197,883 men, results showed that men without metabolic syndrome had significantly higher testosterone levels than those with it, but the average levels remained consistent across different age groups.
  • - Findings indicated that testosterone levels vary significantly based on metabolic health and the time of day, but not strictly due to age, suggesting a need for personalized assessment of testosterone levels instead of relying solely on age-related expectations.

Introduction: Our study examines the factors associated with urologist availability for younger and older men across the country over a period of 18 years from 2000 to 2018.

Methods: The Area Health Resource Files and US Census Data were analyzed from 2000, 2010, and 2018. The younger male population was defined as men aged 20 to 49, and the older male population was defined as ages 50 to 79.

We urge the United States Preventive Services Task Force (USPSTF) to call for a formal review of the evidence regarding testicular self-examination (TSE). Twelve years have since passed since the evidence was last formally analyzed where normally re-reviews occur in 5-year cycles. If they would decide to move forward with this action, we ask for the USPSTF to review their methods for establishing recommendations to optimize their rating system operationalization process.

Infertility specialists may be confronted with the ethical dilemma of whether to disclose misattributed paternity (MP). Physicians should be prepared for instances when an assumed father's evaluation reveals a condition known for lifelong infertility, for example, congenital bilateral absence of vas deferens (CBAVD). When there is doubt regarding a patient's comprehension of his diagnosis, physicians must consider whether further disclosure is warranted.

Objective: To provide the first nationwide characterization of the clinical learning environment in American urological training programs.

Materials And Methods: A survey was sent to program directors (PD) at American Urological Association-accredited urological training programs after requesting their email address from each program coordinator. The 21-question survey was designed to ascertain key components of each training environment: demographics, training model, clinic structure, and resident perception.

Objective: To demonstrate the distribution and impact of fellowship-trained andrology and/or sexual medicine urological specialists (FTAUS) on resident in-service examination (ISE) performance.

Methods: Residency program websites were accessed to create a database of FTAUS in the United States between 2007 and 2017. This database was reviewed by three separate FTAUS and cross referenced with membership lists to the Sexual Medicine of North America Society and the Society for the Study of Male Reproduction.

Background: Prior studies have demonstrated declines in androgen levels in men with cancer and patients undergoing anesthesia and surgery. In this study, we hypothesized that decreased serum androgen levels are prevalent in male patients undergoing radical cystectomy (RC) for bladder cancer and that it persists in the postoperative period. We characterized perioperative androgen hormonal profiles and examined for associated changes indicative of sarcopenia on computed tomography scans in men undergoing RC.

Purpose: This study was undertaken to compare semen quality, hormonal status, and social factors in transgender women seeking fertility preservation with those of fertile cisgender men. Long-range goals are to establish standard practice measures ensuring optimum semen quality for cryopreservation and fertility preservation in transgender women.

Methods: This is a case-control study carried out at an academic medical center.

The field of men's health seeks to improve men's health outcomes by accounting for the specific ways that gender influences male health behaviors. To meet this goal, physicians must also account for the ways that their own cultural assumptions about masculinity influence their clinical practice. Gender is not solely biological.

Objective: To characterize US clinical laboratory reference range reporting and testing methods of follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, and prolactin.

Methods: One hundred and seventeen US laboratories were surveyed. Outcomes measured were variation in lower and upper limits of normal male reference ranges for serum FSH, LH, estradiol, and prolactin, method of analysis and source of reference range RESULTS: The upper limit of normal reference ranges for FSH, LH, estradiol, and prolactin varied substantially across laboratories compared to the lower limits.
