Reproduction in mammals is controlled by the hypothalamo-pituitary-gonadal (HPG) axis under the influence of external and internal factors such as photoperiod, stress, nutrition, and social interactions. Sheep are seasonal breeders and stop mating when day length is increasing (anestrus). However, interactions with a sexually active ram during this period can override the steroid negative feedb...

The aim of the study is to evaluate changes in clinical, hematological and histopathological parameters bitches with vaginal hyperplasia (VH), tumors (VT) healthy reproductive tract (H), respectively. groups formed as; group VH (n=9), VT (n=10) H (n=13). All were examined clinically (vaginal cytology, vaginoscopy), hematologically histopatologically. anestrus oestrus. Reduced levels RBC, HGB, H...

The clouded leopard (Neofelis nebulosa) is an endangered species difficult to propagate in captivity because of sexual incompatibility between paired individuals. Fecal estradiol (E2) and progesterone (P4) metabolites were quantified in 14 females to noninvasively monitor seasonal reproductive patterns and compare ovarian responses to natural mating vs. exogenous gonadotropins. Increased E2 exc...
