Platelet-rich plasma with hair transplants showed no benefits for androgenetic alopecia. A review found finasteride and minoxidil in men arrest progression with partial regrowth. A trial reported cell-enriched fat grafts increased terminal hair counts in early male hair loss. Donor-site density in FUE should not fall below 105 hairs per cm² to preserve appearance. Oral finasteride in men altered sperm parameters and testosterone but caused no sexual dysfunction, with changes reversing after discontinuation.
