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.

Abstract

An excitatory role for norepinephrine (NE) in the regulation of luteinizing hormone (LH) release was first suggested when it was demonstrated that noradrenergic receptor antagonists were able to block ovulation. More recently it has been proposed that NE has both an excitatory role and an inhibitory role in the neuroendocrine regulation of LH release. The excitatory effects may be mediated by alpha-adrenergic receptors and the inhibitory effects may be mediated via beta-adrenergic receptors. These experiments were performed to better understand the role of NE, the receptor type through which NE exerts its effects, and the role of the two major NE pathways in the brain, on LH secretion in the rat.
