,
April 2024 in “The Journal of Steroid Biochemistry and Molecular Biology” This study found that epitestosterone, a stereoisomer of testosterone, is metabolized to 5α-dihydroepitestosterone by human 5α-reductase enzymes, which enhances its androgenic activity and reduces its antagonistic effect on testosterone-driven androgen receptor signaling.
2 citations
,

81 citations
,
May 2007 in “Fertility and Sterility” This review discusses the safety of testosterone therapy for postmenopausal women and concludes that, aside from hirsutism and acne, it appears safe at physiological doses for several years, though more long-term studies are needed.
2 citations
,
September 1971 in “Metabolism, clinical and experimental” In this study, patients with testicular feminization syndrome showed limited anabolic responsiveness to dihydrotestosterone, potentially due to reduced affinity of nuclear receptor sites for androgenic steroids rather than defective testosterone conversion.
9 citations
,
December 2009 in “Cancer Research” This study concluded that both vaginal TEST and Estring may be effective for treating vaginal dryness in breast cancer patients on aromatase inhibitors, with adverse events being rare and manageable.
10 citations
,
October 2006 in “Expert Opinion on Emerging Drugs” This review discusses trends in testosterone therapy use for male hypogonadism and reports no new clinical results, noting a shift towards more convenient and physiological treatments.
5 citations
,
June 2018 in “Elsevier eBooks” This study discusses how testosterone exerts its effects directly or through conversion to metabolites, DHT and estradiol 17β, each influencing different physiological processes, noting that DHT conversion is necessary for certain effects but not for muscle, bone, or erythropoiesis impacts.
12 citations
,
March 2000 in “Clinical Chemistry” This study found that a daily dose of 50 mg DHEA only slightly increased the urinary testosterone/epitestosterone ratio for a short period, without exceeding the IOC's acceptable limit.
December 2023 in “International journal of molecular sciences” This in vitro study found sex chromosome differences affect steroidogenic enzyme activity and androgen receptor expression in human skeletal muscle cells, showing varied responses to testosterone exposure between 46XY and 46XX cells.
June 2022 in “Journal of Experimental Biology and Agricultural Sciences” This study found that steroid hormones influence the quality indicators of fresh and cryopreserved stallion sperm, with testosterone negatively correlated with motility and estradiol positively correlated with survival rate.

February 1975 in “Journal of Steroid Biochemistry”
5 citations
,
June 2004 in “The Journal of The British Menopause Society” This study found that testosterone therapy can enhance sexual satisfaction and mood in surgically menopausal women on oestrogen, though ongoing monitoring and research are needed to assess long-term safety and effects in other groups.
111 citations
,
August 2002 in “Journal of Medicinal Chemistry” This study reports that 2-(1-Adamantyl)-4H-thiochromen-4-on-6-O-sulfamate is the most potent steroid sulfatase inhibitor identified so far, exhibiting 170-fold higher activity than the lead compound estrone sulfamate.
8 citations
,
March 2008 in “Deutsche medizinische Wochenschrift/Deutsche Medizinische Wochenschrift” This case study found that in a male-to-female transgender individual, long-term cyproterone use led to decreased bone mass, which improved with additional oestradiol treatment, highlighting the anabolic role of oestrogens on bone health.
88 citations
,
