Reports that scientists have long wondered why estrogen, a female hormone, is present in males and highly concentrated in their testes. Details on a study in `Nature' which found that estrogen gives sperm its reproductive punch; Observations of Dr. Rex A. Hess.K.A.M....
and the scalp hair is usually more permanent. Thevoice boxis smaller and the vocal cords shorter, giving a higher-pitched voice than in males. In addition, estrogens suppress the activity of sebaceous (oil-producing) glands and thereby reduce the likelihood ofacnein the female. In experimental...
Blood estrogen levels also rise slightly in males before and during puberty. The source of these estrogens is probably the Sertoli cells of the testes (see Chapter 4). The presence of estrogens in males near puberty explains why some pubertal males exhibit slight growth of the mammary glands ...
Saltiki K, Papageorgiou G, Voidonikola P, Mantzou E, Xiromeritis K, Papamichael C, Alevizaki M, Stamatelopoulos K: Endogenous estrogen levels are associated with endothelial function in males independently of lipid levels. Endocrine 2010, 37 (2):329–335....
the level of estrogens in women’s blood rises to 70–80 μg/las a result of the marked intensification of the biosynthesis of the hormone in the placenta. Estrogens cause thickening of the epithelium of the vaginal mucosa, an increase in the weight of the uterus, the rhythmic contraction ...
Estrogen and prolactin (sex hormones associated with female reproduction and development) are also involved in protecting B cells from destruction.Higher levels of these hormones can allow more B cells to circulate in the body. Next, the increased level of B cells can lead to an immune response...
drinking cow's milk were measured and used as a baseline, but there was no group which did not drink milk as a control to eliminate the effects of drinking 1 litre of liquid in 10 minutes. The level of estrogen and other hormones in the urine and serum of the participants were measured...
The relationship between circulating estradiol and thyroid autoimmunity in males. European Journal of Endocrinology. 2013;170(1):63-7. doi:10.1530/EJE-13-0455. Artini PG, Uccelli A, Papini F, Simi G, Di Berardino OM, Ruggiero M, Cela V. Infertility and pregnancy loss in euthroid women ...
It has been documented that estrogen plays a large role in spermatogenesis and in maintaining libido [28]. Estriol [E2] is a most active form of estrogen steroid molecule that has been found to be a clinically significant; however, compared with the female gender, E2 level in men is still...
To assess the effect of altered estrogen to androgen levels on immune system in males in vivo, we selected the established AROM+ mouse model11,12. In this model, human aromatase is ubiquitously expressed, resulting in elevated endogenous levels of estradiol and reduced level of testosterone, and...
