Abstract
Effects of non-steroidal aromatase inhibitor letrozole on ovarian function in ewe were investigated through testing the hypothesis that letrozole will arrest the growth of dominant follicles, resulting in the emergence of a new follicular wave at a predictable post-treatment interval. Treatment ewes (n = 10) were treated using an intravaginal sponge (regardless of the stage of estrus) containing 7.5 mg letrozole for five days followed by prostaglandin injection. The control group (n = 10) was treated with gonadotropin prostaglandin gonadotropin (GPG) protocol for ovarian synchronization. Ovarian structures were daily monitored with trans rectal ultrasonography concomitant with blood sampling. Commercial enzyme-linked immunosorbent assay Kits assigned steroid concentration of estradiol, testosterone and progesterone. Some biochemical parameters including blood glucose, total proteins, lipid profiles were measured as a preliminary scree...
