Turner's Syndrome is the most frequent cause of female hypogonadism. Puberty must be pharmacologically induced in over 80% of these girls. Induction must be completed in a manner closest to physiology as possible. It is ...

This study investigated the effects of growth rates and compensatory growth on puberty attainment in Nellore heifers. Nellore heifers (n = 120), weaned at 8 ± 0.75 mo of age, were blocked by sire and BW (180 ± 8.6 kg) and ...

Age at puberty in beef heifers can influence economic efficiency of beef production through effects on both age at first calving (2 vs. 3+ years of age) and the time of conception of heifers in their initial breeding season. ...

Aim: Hormone replacement therapy with testosterone for pubertal induction in boys with congenital hypogonadotropic hypogonadism (CHH) achieves virilization but not spermatogenesis. By contrast, human chorionic gonadotropin ...

The objectives of this study were 1) to monitor corpus luteum (CL) dynamics after two different protocols of ovulation induction in prepubertal Nellore heifers, and 2) to determine differences in luteal function. Fifty-seven ...

Optimal reproductive fitness is essential for the biological success and survival of species. The vomeronasal organ is strongly implicated in the display of sexual and reproductive behaviors in female mice, yet the roles ...

In view of its similar structure and function to luteinizing hormone (LH), human chorionic gonadotropin (hCG) has conventionally been used as the main hormone to induce estrus and ovulation in sows. Recently, it has been ...
