February 2025 in “East African Scholars Journal of Medical Sciences” In this study conducted at Bangabandhu Sheikh Mujib Medical University, researchers reported that males with androgenetic alopecia had significantly higher levels of serum LH, prolactin, testosterone, DHEA-S, and free androgen index, and lower levels of serum FSH and SHBG compared to those without hair loss.
January 2025 in “Biomedicines” In this study, female rats given high doses of testosterone showed decreased endometrial thickness and lower mRNA levels of components in the LIF signalling pathway, indicating that excessive testosterone may negatively impact endometrial receptivity and potentially affect fertility.
This study found that women undergoing mid-trimester termination of pregnancy exhibited increased cumulative cortisol and testosterone levels in hair samples, higher anxiety, but better stress coping strategies two months post-abortion, suggesting hair testosterone may be linked to emotional vulnerability such as neuroticism during this period.
January 2025 in “Journal of Food Biochemistry” In this study, 2′‐Fucosyllactose (2′‐FL) administration significantly reduced hair loss and increased hair length and thickness in a testosterone-induced androgenic alopecia mouse model, suggesting potential as a therapeutic agent for AGA.
November 2024 in “Psychoneuroendocrinology” This study found that hair steroid analysis effectively detected increased hormone levels from both a single testosterone dose and laboratory-induced stress, revealing individual context factors like relationship status also impact hair hormone concentrations.
September 2024 in “International Journal of Molecular Sciences” This study found that administering a supraphysiological dose of testosterone to female rats significantly reduced estrogen and progesterone levels, disrupted sex steroid receptor expression, and interfered with the embryonic implantation window, indicating potential implications for androgen-related endometrial conditions.
May 2024 in “Current perspectives on medicinal and aromatic plants” This mini review explores the potential of herbal testosterone 5α-reductase inhibitors for treating androgenetic alopecia, suggesting they might offer fewer side effects and better tolerability than traditional treatments like finasteride and minoxidil.
In this systematic review, researchers observed that Toxoplasma gondii infection is associated with alterations in testosterone levels, generally increasing in humans but showing mixed effects in animals, highlighting a complex relationship that warrants further investigation.
March 2024 in “Revista Ciências da Saúde CEUMA” This study found that administering testosterone increased the expression of sexual behavior and elevated serum testosterone and DHT levels in female capuchin monkeys, hinting at potential insights into testosterone use and its risks in humans.
March 2024 in “Journal of Applied and Natural Science” This study found that administering an alcoholic extract of Mentha spicata leaves significantly reduced testosterone levels and aggressive behavior in female rats with elevated testosterone, suggesting its potential protective role against such symptoms.
January 2024 in “Al-Ameed journal for medical research and health sciences” This review summarizes the latest evidence on testosterone, detailing its clinical indications, diagnostic tests, and impacts on various male organs, while also noting its association with aging, metabolic disorders, and increased mortality risk due to androgen deficiency.
January 2024 in “Journal of Medicinal Food” This study found that Nephelium lappaceum extract restored hair growth more effectively than finasteride in mice with testosterone-inhibited hair growth, suggesting its potential as a nutraceutical for hair growth.
January 2024 in “Life sciences” This study observed that in spontaneously hypertensive rats, testosterone's effects on endothelium-dependent vasodilation involved reduced nitric oxide levels, increased oxidative stress, and greater reliance on endothelium-dependent hyperpolarization, with variations in these responses noted when testosterone was combined with either anastrozole or finasteride.
November 2023 in “JAAD case reports” This research indicates that androgens may drive hidradenitis suppurativa in some patients, as they show higher testosterone levels compared to nonaffected controls, and testosterone-lowering medications are established treatments for milder cases.
November 2023 in “PubMed” This study found significant gender differences in total testosterone and dehydroepiandrosterone sulfate levels among noncritical COVID-19 patients, which were associated with severity markers in males.
October 2023 in “FASEB bioAdvances” This study investigated the effects of Akkermansia muciniphila on testosterone-induced hair growth inhibition in mice, finding that both live and pasteurized forms significantly encouraged hair growth and increased hair follicle size and growth factor levels compared to testosterone treatment alone.
October 2023 in “The Journal of urology/The journal of urology” This study reported no association between higher serum testosterone or dihydrotestosterone levels and the incidence or progression of lower urinary tract symptoms in asymptomatic or symptomatic men in the REDUCE trial, challenging the belief that elevated androgens contribute to these symptoms.
