Capsaicin
Capsaicin (CAP) is the active substance of red hot peppers, Capsicum annuum. The red hot pepper is a member of Solanacea family.
Biotech Histochem. 2012 Sep 27 reported a study of effects of capsaicin on testis ghrelin expression in mice.
The
study demonstrated that when low dose CAP (0.02% CAP in standard chow)
was added to the diet of rats during the developing period, ghrelin
expression decreased significantly in Leydig cells, whereas serum
testosterone levels and spermatogenic cell activity increased,
especially in the adult experimental group.Whether the effects we
observed extend to other animals and humans remains
to be investigated.

The histological investigation on the testes of mice after an
application of capsaicin dose of 1 mg/kg body mass everyday for a week
These fi ndings suggest that capsaicin may have a stimulating function in the testes.

Researchers investigated on the effects of feeding a diet containing red hot
pepper on the reproductive organs of the chicken. The diet
consists of 1% red hot pepper (10 g/kg diet), the chickens caused faster
development of the reproductive system organs and lower abdominal fat.
