The plasma concentration of estradiol in males is 2-3 ng/dl and its production rate in blood is 25-40 g/24 h; both of these values are significantly higher than in postmenopausal women. Plasma levels of estradiol do not necessarily reflect tissue-level activity as peripherally formed estradiol...

A sixth-grade polynomial was fitted to each child's growth data, giving growth velocity and age at PHV.Growth velocity increased by 50% from prepubertal growth to PHV at a morning testosterone level of 3.1 nmol/l (95% confidence interval 2.4-4.2), EC50. The corresponding EC50 of 17β-...
Estradiol (E2) is the most active estrogenic female sex hormone, and is used in the hormonal therapy for menopausal symptoms. Unbalanced oestrogen level alongside with other hormones, like luteinising hormone (LH) and follicle stimulating hormone (FSH), was noticed in polycystic ovary syndrome (PCO...

The results of our study has shown that: in the males suffered from either type I or type II diabetes mellitus with disturbance of reproductive function, the level of serum progesterone is elevated mostly in case of type II diabetes mellitus (78,3%), mainly in the patients more than 40 ...
Both fadrozole and estradiol produce masculinization of partner preference in this species, while neither treatment affects males. Also, it is not known whether the sex reversing effect of fadrozole is due to gonadal sex reversal or to suppression of embryonic estrogen synthesis by the brain. One ...
The women were allocated to 4 groups: women with cycles whose plasma FSH level was less than 40 mIU/mL (A; n = 16), women with cycles whose plasma FSH level was greater than 40 mIU/mL (B; n = 19), women who were amenorrheic for less than 1 yr (C; n = 13), and women ...
