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.

It is well established that LH action is mediated primarily by adenylate cyclase/cAMP. Conversely, the role of inositol phosphate/calcium in LH signalling has only recently been investigated.

Abstract
It is well established that LH action is mediated primarily by adenylate cyclase/cAMP. Conversely, the role of inositol phosphate/calcium in LH signalling has only recently been investigated. We examined the effects of gonadotrophins on intracellular calcium mobilisation in HEK293 cells transiently transfected with human wild type or chimeric gonadotrophs receptors (n=3400). Intracellular free calcium concentration was measured using fura-2 microspectrofluorimetric techniques. Human LH (2-4 μg/ml) arid CG (10 IU/ml) consistently evoked oscillatory calcium signals in HEK293 cells transfected with hLHr, whereas hFSH (2-4 μg/ml) failed to elicit any calcium responses.
