Caption

Gnrh1^hpg/Gnrh1^hpg mice are characterized by an overall underdevelopment of the reproductive tract. Male mice have a small penis and scrotum and a short ano-genital distance. All male reproductive organs are present but immature. The testes are small and undescended. Spermatogenesis is arrested, usually by the diplotene stage. The vagina of female mice does not open fully, the uterus is thread-like, and the ovaries are very small.
