Finasteride causes lasting fertility decrease in rats.
research Molecular basis of androgen action on human sexual desire
Testosterone significantly affects sexual desire in both men and women, but its impact on women is more complex and influenced by psychological factors.

Selecting Angus cattle for earlier puberty lowers prolactin levels but doesn't affect hair growth.
research From bedside to bench: regulation of host factors in SARS-CoV-2 infection
The conclusion is that certain genetic factors and blood types may affect COVID-19 severity, but changes in ACE2 and TMPRSS2 genes are not clearly linked to it.
research Hidradenitis suppurativa
Antiandrogen therapy may be beneficial for women with hidradenitis suppurativa.
research Planning for Maximum Coverage in Surgical Hair Restoration
Walter P. Unger suggests using advanced hair transplant techniques for broader coverage, as they provide natural results and use donor tissue efficiently, while also recommending personalized planning due to the unpredictable progression of baldness.

Neutered ferrets often develop hyperadrenocorticism, with symptoms like hair loss and lethargy, and androstenedione is a key indicator for diagnosis.
research Global Landscapes of Human Phenotypic Variation in Inherited Traits
Different human traits like skin color and hair type vary between populations due to genetic adaptations to the environment.
research Testosterone and dihydrotestosterone production in genetically furless and furred male rabbits and effects on growth.
Furless male rabbits grew slightly faster and heavier than furred ones, but testosterone levels were not the cause.
