Abstract:
Kisspeptin is an essential gatekeeper of reproductive function. During pregnancy high circulating levels of kisspeptin have been described, however the clear role of this neuropeptide in pregnancy remains unknown. We tested the existence of rhythmic kisspeptin expression in human full-term placenta from healthy pregnant women at six different time points during the day. The data obtained by Western blotting were fitted to a mathematical model (Fourier series), demonstrating, for the first time, the existence of a circadian rhythm in placental kisspeptin expression.

In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair...
