Abstract
In order to characterize and compare the pattern of inhibin production in the follicular phase between patients of the clomiphene citrate/human menopausal gonadotropin (hMG) and Buserelin/hMG protocols in in-vitro fertilization, serum inhibin levels from 20 patients in each protocol were measured. The patients were matched for age and had tubal diseases only. It was hypothesized that the serum inhibin levels would be different in these two groups due to possible local actions of clomiphene citrate and Buserelin (a GnRH agonist) on the ovary.

Abstract
A delicate balance of steroid and gonadotrophic hormones is essential for intrafollicular oocyte maturation and successful fertilization and embryonic development. Previous studies have demonstrated that a superovulatory dose of pregnant mare serum gonadotrophin (PMSG) has excessive gonadotrophic activity and alters intrafol1icular steroid hormone levels. In a series of four experiments, the morphology of oocytes and embryos retrieved from immature rats, treated with either a low or high dose of PMSG, and mature, cycling rats was compared to determine whether a superovulatory dose of PMSG has an adverse effect on oocyte maturation and subsequent fertilization and embryonic development in immature rats. Morphological criteria for the assessment of intraoviductal oocyte aging were established in the first experiment.

There is increasing evidence to suggest that activin can function as an autocrine/paracrine regulator in various tissues, including the reproductive system. At the cellular level, activin acts via a family of activin receptor (ActR) subtypes which includes two type I (ActRI and ActRLB) and two type…

Abstract
There is increasing evidence to suggest that activin can function as an autocrine/paracrine regulator in various tissues, including the reproductive system. At the cellular level, activin acts via a family of activin receptor (ActR) subtypes which includes two type I (ActRI and ActRLB) and two type II (II and ILB) receptors. The role of activin in the human placenta is not clearly understood. In this study, the detection of inlubin/activin subunit and ActRI mRNA were examined in first trimester cytotrophoblasts, term cytotrophoblasts, extravillous trophoblast (EVT) cells, immortalized extravillous trophoblast (LEVT) cells, JEG-3 cells, decidual tissue, and decidual cells.

Abstract
In vitro fertilization (IVF) has been achieved in several mammalian species, including humans. Using the technique of IVF and embryo transfer, pregnancies can now be established in infertile women and thousands of live births have occurred. However, many of the embryos transferred to the uterus fail to achieve or sustain implantation. The failure of implantation has raised questions about the possible detrimental effect of superovulation on chromosomal complements. In this study, the hypothesis that chromosomal aberrations exist in mouse preimplantation embryos and human unfertilized oocytes after superovulation, was tested. The incidence of aneuploidy in spontaneously ovulated group (5.6%) was similar to that reported by others.

Abstract
A sperm specific and species conserved monoclonal antibody (HS-63) was shown to inhibit in vitro fertilization of mouse oocytes and human sperm penetration to zona-free hamster ova. The sperm antigen (SA-63) which reacts with HS-63 was found to be localized on the sperm acrosome. Following sperm capacitation, this antigen becomes exposed and is shed after the acrosome reaction. SA-63 may be involved in the sperm acrosome reaction during the initial fertilization process.
