Hormones mediate major physiological and behavioural components of the reproductive phenotype of individuals. To understand basic evolutionary processes in the hormonal regulation of reproductive traits, we need to know whether, and during which reproductive phases, individual variation in hormone concentrations relates to fitness in natural populations. We related circulating concentrations of...

1.1 Regulation of female reproductive system Regulation of female reproductive system consists of very complex interactions between the hypothalamus, neurohypophysis and ovaries. Beginning from the embryologic stage, female reproductive system is regulated by the brain. Ovarian hormone production is supressed by the hypothalamo-hypophyseal control mechanism till the end of the childhood period ...

im of the study: Rasayan drugs act inside the human body by modulating the neuro-endocrino-immune system. Vaajikaran rasayan is the special ategory of rasayan which investigate the reproductive system and enhance sexual function. Curculigo orchioides, Astercantha longifolia and ucuna pruriens are well known vajikaran rasayan herbs. The effect on sexual behaviour and reproductive parameters are ...

Appropriate regulation of reproductive processes are dependent upon the integrity of pituitary function. In this selected review, we evaluate the evidence that certain environmental compounds exert their effect on reproductive function via a direct action on the pituitary gland. We also discuss examples of changes in pituitary hormone secretion that occur in response to changes in neuronal or g...

background: detection of best predictor of ovarian reserve in patients with temporarily or consistently elevated early follicular phase serum levels of fsh is one of the most important goals in assisted reproductive technique (art). objective: to evaluate whether high level of anti-mullerian hormone level is related to success of art in patients with temporarily or consistently elevated early f...

Studies in our laboratory continue to investigate the mechanism by means of which thyroid hormone influences reproductive physiology in the female rat. Thyroid hormone has been reported to exert effects upon the reproductive system and pregnancy in many types of animals, including human beings. These findings have been reviewed by Leathern (11). However, the mechanisms by means of which thyroid...

Until 2000 it was believed that gonadotropin-releasing hormone (GnRH) was the sole regulator of hypophyseal gonadotropes. In 2000, the discovery of a gonadotropin inhibitory hormone (GnIH) initiated a revolution in the field of reproductive physiology. Identification of GnIH homologues in mammals, the arginine-phenylalanine-amide (RFamide)-related peptides (RFRPs), indicated a similar function....
