Given E2's role in male hypothalamic-pituitary-gonadal function and complex interfaces with the immune system, these results have important implications for models of male life history as rates of overweight and obesity rise in populations around the world. Am. J. Hum. Biol. 26:376383, 2014. ...
It has been suggested that increased prolactin levels may contribute to decreased libido in aging male primates. To test this hypothesis, the association o... KC Chambers,CH Phoenix 被引量: 0发表: 2019年 The gonadotropin response of men with varicoceles to a four-hour infusion of gonadotropin...
Estradiol test is used to test for a variety of conditions as well as evaluate certain treatments. This test may be ordered to check: How well the ovaries, placenta, or adrenal glands work For signs of an ovarian tumor If male or female body characteristics are not developing normally ...
The production of sex steroids by follicular cells is proposed to be influenced by the maturity of the incumbent oocyte. Thus steroid levels may reflect suitability of an oocyte for IVF. We examined follicular fluids and granulosa cell production of steroid from IVF patients in order to test the...
Monolayer cultures were prepared from pituitaries of prepubertal and pubertal male rats aged 21 and 50 - 60 days respectively. By comparison with controls in steroid-free medium, pituicytes were incubated for 45 h with 1.10-8 M estradiol (E2),various LHRH con- centrations (J .10- 10 to ...
Oestrogens are used in male-to- female transsexuals to develop and maintain secondary sexual characteristics. Although ethinylestradiol and conjugated oestro- gens have been used for this purpose, and there is some evidence that such use can improve vascular function,1 others consider ethinylestradiol...
Myotubes from postmenopausal women and age-matched male donors were treated with 10 nM testosterone or E2 for 4 days, and assays were performed to measure metabolic readouts, signal transduction, and mRNA expression. Testosterone and E2 treatment enhanced insulin-stimulated glucose incorporation...
We argue here that, unlike links between testosterone and male social relationships, theoretical foundations for such relationships with female reproductive steroid hormones are lacking, especially given the primary role of these steroids in regulating female reproductive function. Further longitudinal studies...
The LD female's preference for male odors is estradiol-dependent and eliminated by ovariectomy, whereas the SD female's preference for female odors is affected neither by ovariectomy nor estradiol (E) (Ferkin and Zucker, 1991). Same-sex female prosocial behavior in SDs extends to social ...
The effect of free E2 levels on survival was evaluated by log rank test. Male pts were categorized as high or low E2 based on values above or below the median (0.42 pg/ml; range: 0.1–2.95).The assay range for normal men is 0.2 - 0.5 pg/ml; in pre- and postmenopausal women, the...
