Stress and the Reproductive Cycle
THE IDEA that by activating the hypothalamic-pituitary-adrenal (HPA) axis, stress and overt or latent psychological disturbances have the potential of inhibiting the hypothalamic-pituitary-gonadal (HPG) axis has been circulated for a long time (1). It is generally thought that, if severe enough, this condition may lead to the suppression of the normal menstrual cycle in a syndrome referred to a...
متن کاملIMMUNOSUPPRESSION IN HUMAN UTERINE TISSUES THROUGHOUT THE REPRODUCTIVE CYCLE
The purpose of this study was to investigate and compare whether the explant supernatants prepared from endometrial tissues during the proliferative phase, secretory phase and early pregnancy differ in immunosuppressive activity. Specimens of nonpregnant endometrium from hysterectomies and normal first trimester decidua following elective aspiration termination of pregnancy were obtained. ...
متن کاملStress and the reproductive axis.
There exists a reciprocal relationship between the hypothalamic-pituitary-adrenal (HPA) and the hypothalamic-pituitary-gonadal (HPG) axes, wherein the activation of one affects the function of the other and vice versa. For example, both testosterone and oestrogen modulate the response of the HPA axis, whereas activation of the stress axis, especially activation that is repeating or chronic, has...

متن کاملGonadal changes and serum steriod levels during the annual reproductive cycle of the pearl oyster Pinctada fucata gould
The annual reproductive cycle of peal oyster Pinctada fucata was characteised by documenting gonadal development and changes in serum levels of estradiol-17b (E2), testosterone (T) and progesterone (P) in the wild bivalve caught in natural beds in the Persian Gulf throughout the year. Bivalve populations employed in this study spawn in June-July and November-December. The pearl oysters had grou...
