Males born to obese mothers more likely to suffer health issues as adults
Males born to obese women are more likely to be overweight at birth and develop metabolic complications in later life, including liver disease and diabetes.
Desai Sethi Urology Institute Researcher Finds “Sneaky Testosterone” Might Signal Worse Outcomes for Men with Prostate Cancer
Findings from the newly published study in The Journal of Clinical Investigation suggest a large proportion of men have testosterone concentrations that are much higher in and around the prostate than traditional blood draws suggest. And this elevated exposure near the prostate increases the risk of poor outcomes after surgical removal of the prostate gland.
After age 70, higher BMI and the presence of diabetes or cancer associated with lower testosterone in men
An analysis of more than 25,000 men found that sociodemographic, lifestyle, and medical factors including age >70 years, hypertension, higher body mass index (BMI), diabetes, and cancer, were associated with lower testosterone concentrations.
Hormone alters electric fish’s signal-canceling trick
New research shows that the hormone testosterone — which naturally triggers male electric fish to elongate the electric pulses they send out during the breeding season — also alters a system in the fish’s brain that enables the fish to ignore its own electric signals.

Prompt testosterone treatment improves mental health of transgender, gender-diverse people
Receiving rapid access to testosterone therapy reduced feelings of gender dysphoria and led to a clinically significant reduction in depression as well as a 50% reduction in suicidality among transgender and gender diverse adults, according to research being presented Sunday at ENDO 2023, the Endocrine Society’s annual meeting in Chicago.
Full recovery may be possible among men who use steroids for muscle growth
There may be hope for full recovery among men who wish to stop using anabolic-androgenic steroids for muscle growth, according to data being presented on Saturday at ENDO 2023, the Endocrine Society’s annual meeting in Chicago, Ill.
Study reveals how treatment-resistant prostate cancer provides its own hormonal fuel
A new study in mice, led by researchers at Washington University School of Medicine in St. Louis, explains how prostate cancer senses a drop in testosterone levels due to common anti-hormone therapy and then begins making cholesterol — a necessary precursor to testosterone — to generate its own testosterone to fuel tumor growth. The study also points to a possible drug combination that may stop the cancer from feeding its own growth.
Study Reveals New Understanding of How Androgen Therapy Affects Breast Tissue
New insights into the effects of a hormonal treatment for transgender men, discovered by Cedars-Sinai investigators, could have implications for the treatment of breast cancer.
Standard threshold for low testosterone doesn’t apply to young men
The standard cutoff point for low testosterone levels may not be accurate for men in their mid-forties and younger, reports a study in The Journal of Urology®, an Official Journal of the American Urological Association (AUA). The journal is published in the Lippincott portfolio by Wolters Kluwer.
Mouse model of transgender men finds active testosterone worsens IVF outcomes
Active testosterone therapy for transgender men may negatively impact IVF outcomes, suggests a mouse study being presented Monday at ENDO 2022, the Endocrine Society’s annual meeting in Atlanta, Ga.
Testosterone improves quality of life, sexual function, and delayed verbal recall in men with uncontrolled type 2 diabetes
Testosterone replacement therapy improved sexual symptoms, libido, symptom severity, delayed verbal recall and overall quality of life among people with poorly controlled type 2 diabetes and hypogonadism, according to research being presented Monday at ENDO 2022, the Endocrine Society’s annual meeting in Atlanta, Ga.
Analysis finds little evidence of heart problems in men undergoing testosterone treatment
Previous clinical trials have provided insufficient evidence to decide whether testosterone causes heart problems in men during the first year of treatment, according to research being presented Monday at ENDO 2022, the Endocrine Society’s annual meeting in Atlanta, Ga., and published in The Lancet Healthy Longevity.
Multi-decade research links fathers’ testosterone production to their adolescent experiences with their own fathers
Notre Dame’s Lee Gettler and his collaborators have drawn on data collected over more than 30 years from almost 1,000 men in the Philippines to help shed light on the importance of adolescence and father-son experiences to sons’ adult testosterone patterns.
University of Miami Urologists Study How Plant-Based Diets Impact Men’s Health
Studies show that plant-based diets can help lower prostate-specific antigen (PSA levels), improve serum testosterone and erectile dysfunction.
Does testosterone influence success? Not much, research suggests
With the Olympics underway, higher testosterone has often been linked to sporting success, and other kinds of success too. But beyond sport, new research has found little evidence that testosterone meaningfully influences life chances for men or women.
For men, low testosterone means high risk of severe COVID-19
A new study from Washington University School of Medicine in St. Louis suggests that, among men, low testosterone levels in the blood are linked to more severe COVID-19. The study contradicts widespread assumptions that higher testosterone may explain why men, on average, develop more severe COVID-19 than women do.
Inflammatory diet linked to testosterone deficiency in men
Consuming a diet high in pro-inflammatory foods – including foods that contain refined carbohydrates and sugar as well as polyunsaturated fats – may be associated with increased odds of developing testosterone deficiency among men, suggests a study in The Journal of Urology®, Official Journal of the American Urological Association (AUA). The journal is published in the Lippincott portfolio by Wolters Kluwer.
Study finds oral testosterone therapy undecanoate is effective, with no liver toxicity
An industry-supported study of an oral testosterone replacement therapy (TRT), testosterone undecanoate (TU, brand name Jatenzo) finds it is an effective, long-term treatment for men with low testosterone levels, with no evidence of liver toxicity. The findings are being presented virtually at ENDO 2021, the Endocrine Society’s annual meeting.

Plant-Based Diets Support Healthy Testosterone Levels
Men who follow plant-based diets have testosterone levels that are basically the same as the levels in men who eat meat, a study shows. This finding dispels a widespread notion that men need large amounts of animal protein in order to support healthy levels of this hormone.
Lowering Testosterone May Reduce Severity of COVID-19
