Estrogens in Human Male Gonadotropin Secretion and Testicular Physiology From Infancy to Late Puberty

Frontiers in Endocrinology, 2020
Several reports in humans as well as transgenic mouse models have shown that estrogens play an important role in male reproduction and fertility. Estrogen receptor alpha (ERα) and beta (ERβ) are expressed in different male tissues including the brain ...

Structural plasticity of the hippocampus in response to estrogens in female rodents

Molecular Brain, 2019
It is well established that estrogens affect neuroplasticity in a number of brain regions. In particular, estrogens modulate and mediate spine and synapse formation as well as neurogenesis in the hippocampal formation.

Inhibition of Androgen-Independent Prostate Cancer by Estrogenic Compounds Is Associated with Increased Expression of Immune-Related Genes

Neoplasia: An International Journal for Oncology Research, 2006
The clinical utility of estrogens for treating prostate cancer (CaP) was established in the 1940s by Huggins. The classic model of the anti-CaP activity of estrogens postulates an indirect mechanism involving the suppression of androgen production ...
