The present study aimed to compare between the effect of hCG and GnRH analogue treatment post laparoscopic insemination on reproductive performance of ewes. Oestrus synchronization was performed for 120 ewes (Najdi=60 and Naeimi=60) using intra-vaginal progesterone sponge and equine chorionic gonadotrophin (eCG). Semen was collected from six proven fertile rams by artificial vagina. Ewes were laparoscopic inseminated 48–50 h after sponge withdrawal,and divided randomly in...

Antral follicle waves in mares are considered a model for ovarian function in women, and can be sampled with relative ease in vivo or following ovary removal to investigate the regulation of follicle growth. To begin determine the effects of disease which may dysregulate follicular granulosa (GC) or theca cell (TC) proliferation, this study characterised 41 antral follicle wall H&E sections recovered from ovaries of 16 mares that were classified as healthy or suffered from...
