research Darwinian Health and Other Contradictions
The document concludes that understanding health requires considering evolutionary perspectives on reproductive fitness, and recognizing the complexity of factors like diet, testosterone, and sexual orientation.
research Pattern Baldness: Its Genetics Revisited
Pattern baldness is likely caused by a dominant gene influenced by testosterone levels, making it more common in men.
research Inhibition of Hair Growth by Testosterone in the Presence of Dermal Papilla Cells from the Frontal Bald Scalp of the Postpubertal Stumptailed Macaque
Testosterone can slow hair growth in adult monkeys, but a blocker called RU 58841 can counteract this and potentially help hair regrow.
research Spontaneous Lesions of Endangered Geriatric Julia Creek Dunnarts (Sminthopsis Douglasi, Archer 1979) with Emphasis on Reproductive Pathology
