Differential behavioral effects of gonadal steroids
in women with and in those without premenstrual syndrome.
Because of the critical role that gonadal steroids
play in regulating reproductive development, any change in their production or metabolism could potentially disrupt the normal reproductive cycle.
The clinical, imaging and laboratory findings (adrenal and gonadal steroids
, pituitary hormones, and karyotype) were consistent with 17-[beta]-HSD3 deficiency.

and growth hormone in intact and hypophysectomized turtles," General and Comparative Endocrinology, vol.
They examined a wide spectrum of testosterone levels, and the adverse effects of different levels, by temporarily suppressing the normal endogenous gonadal steroids
of healthy men aged 20-50 years using subcutaneous goserelin.
Mechanism of clonal expansion of individual myometrial cells involves interplay of gonadal steroids
and subsequent expansion of autocrine, paracrine and endocrine growth factors.
The precise influence of gonadal steroids
hormones in pain is not well understood, therefore there are possible neuromodulatory roles of sex hormone on the opioid system.
Regulation of the steroid secretion from the gonads in the male and female is under complex regulatory mechanisms that include the feedback actions of gonadal steroids
hormones and release of many neurotransmitters at the level of hypothalamus and the gonads.
Thus, gonadal steroids
and peptides exert their effects on the gonadotropins either directly or via e hypothalamus (LEVAVI-SIVAN et al., 2010).
With due attention to PCOS which is the most common female endocrine disorder in women of reproductive age and the therapeutic activity of chamomile (Flavonoids), we saught to (1) compare the circulating levels of gonadotropins and gonadal steroids
before and after injection of Chamomile extract in PCO induced rats (2), study the signs of PCOS in the ovarian tissue and (3) change in the number of dominant follicles upon Chamomile extract administration.
