1 Laboratory animal practice-Some veterinarians work in a university or industrial laboratory and are responsible for the care and treatment of laboratory animals of any species (often involving bovines, porcine species, felines, canines, rodents, and even exotic animals).
High estrogen levels in men contribute to prostate cancer and heart disease as well as gynecomastia (enlarged breasts).As the testosterone is transformed into estrogen the low levels of testosterone can cause many unpleasant symptoms including loss of muscle mass, fatigue, low libido, erectile dysfunction.s teenagers, men have high levels of testosterone and low levels of estrogen. As they age, testosterone levels in men decrease while their estrogen levels increase.
For the most part yes, but there is estrogen found in all men, and women do need small amounts of testosterone. There is, however, a growing need to understand the effects of estrogen in men. Like all hormones, estrogen needs to be kept in balance in both men and women. Chronic health conditions are more likely to occur in men as a result of estrogen levels becoming too high. Testosterone and estrogen are actually very closely related in the body. A look at their chemical structure reveals only subtle differences. Yet, the differences of the effects of these two hormones on the body are substantial.
