Variable Response to Hormonal Induction of Multiple Ovulation in Quail

I-35: Induction of Ovulation in Clomiphen Resistant

Polycystic ovary syndrome (PCOS) is a heterogeneous disorder in which chronic anovulation is a common feature despite the presence of multiple micro- structures in the ovaries. A growing body of evidence has suggested that serum hyperinsulinemia and as the result hyperandrogenemia contributes to the excess ovarian androgen secretion observed in women with PCOS. The standard therapy for anovulat...

The Effect of Flutamide on Ovulation Induction in PCOS Patients

Hormonal priming, induction of ovulation and in-vitro fertilization of the endangered Wyoming toad (Bufo baxteri)

The endangered Wyoming toad (Bufo baxteri) is the subject of an extensive captive breeding and reintroduction program. Wyoming toads in captivity rarely ovulate spontaneously and hormonal induction is used to ovulate females or to stimulate spermiation in males. With hormonal induction, ovulation is unreliable and egg numbers are low. The sequential administration of anovulatory doses of hormon...

Ovulation induction in perspective.

It has been suggested recently that, in some quarters, IVF be offered as first-line therapy to all infertile couples, regardless of the type of infertility. Hence, the time was thought right to scrutinise the results and complications of ovulation induction for anovulatory infertile couples. In addition to examining the outcome of conventional treatment with gonadotrophins and clomiphene citrat...

Ovulation Induction in Sows

This study reviewed the protocols for ovulation induction in sows by human chorionic gonadotropin (hCG) and gonadotropin releasing hormone (GnRH). In pigs, it was documented that ovulation usually occurred about 70% of the way through oestrus. However, the duration of oestrus in sows highly varies, producing difficulty in performing artificial insemination (AI) in sows at optimal time. In pract...
