Ovulation Induction in In-Vitro Fertilization

Impact of The Endometrioma on Ovarian Response and Pregnancy Rate in In Vitro Fertilization Cycles

Induction of ovulation in phase I of the in vitro fertilization and embryo transfer programme at Tygerberg Hospital.

Two different protocols for ovulation induction used in phase I of the in vitro fertilization (IVF) programme at Tygerberg Hospital are presented. Previous experience with gonadotrophins and clomiphene citrate was applied in the development of the protocols. By means of experience gained during ovulation induction it was possible to establish critical values for the parameters of follicle matur...

Tubal Pregnancy Associated with Endometrial Carcinoma after In Vitro Fertilization Attempts

Endometrial carcinoma is rarely seen during reproductive ages and commonly related to infertility, polycystic ovarian syndrome (PCOS), and obesity. Pregnancy associated endometrial carcinoma is even rarer and this is the second case reported in the literature concerning tubal pregnancy associated endometrial carcinoma. We present a case of a 36-year-old woman with a history of PCOS, infertility...

In vitro fertilization and embryo transfer: a brief overview.

The in vitro fertilization process breaks down into three essential components: induction of ovulation, fertilization of the oocyte, and development of embryos that are transferred into the uterus. Problems may arise resulting in failure at any one of these junctions. In 1984, the World Congress on In Vitro Fertilization was held, looking at 9,641 laparoscopies yielding 1,101 clinical pregnanci...

Artificial fertilization of Senegalese sole (Solea senegalensis): hormone therapy administration methods, timing of ovulation and viability of eggs retained in the ovarian cavity

One method to overcome the difficulties involved in reproducing first generation Senegalese sole that are born in captivity (F1) is to obtain gametes by stripping and then using them for artificial fertilization. The aim of this paper was to determine an appropriate protocol for hormonal induction of ovulation and artificial fertilization. To induce ovulation, two different GnRHa administration...

Ovarian epithelial dysplasia after ovulation induction: time and dose effects.

BACKGROUND Ovarian epithelial dysplasia was first described after prophylactic oophorectomies for genetic risk. Ovarian stimulation has been considered as a risk factor of ovarian cancer by Fathalla's incessant ovulation theory. In this study, we have investigated the risk of ovarian dysplasia after ovulation induction. METHODS We reviewed 99 oophorectomies or cystectomies between 1990 and 20...
