Pubertal gynecomastia

October 31, 2008

Take a look for surgeons of gynecomastia surgery at hospitals of Hyderabad in India. Estrogens, however, rise throughout the entire day. Some studies have shown that a decreased androgen to estrogen ratio exists in boys with pubertal gynecomastia when compared with boys who do not develop gynecomastia. Furthermore, another study showed increased aromatase activity in the skin fibroblasts of boys with gynecomastia. Thus, the mechanism by which pubertal gynecomastia occurs may be due to either decreased production of androgens or increased aromatization of circulating androgens, thus increasing the estrogen to androgen ratio. The third age range in which gynecomastia is frequently seen is during older age (>60 years). Although the exact mechanisms by which this can occur have not been fully elucidated, evidence suggests that it may result from increased peripheral aromatase activity secondary to the increase in total body fat, coupled with mild hypogonadism associated with aging.

Physiologic gynecomastia

October 20, 2008

Medical tourism is going to deal with surgeons of gynecomastia surgery at hospitals of Chennai in India run by corporate entities.  Gynecomastia, breast development in males, can occur normally during three phases of life. The first occurs shortly after birth in both males and females. This is caused by the high levels of estradiol and progesterone produced by the mother during pregnancy, which stimulates newborn breast tissue. It can persist for several weeks after birth and can cause mild breast discharge called “witch’s milk”. Puberty marks the second situation in which gynecomastia can occur physiologically. In fact, up to 60% of boys have detectable gynecomastia by age 14. Although it is mostly bilateral, it can occur unilaterally, and usually resolves within 3 years of onset. Interestingly, in early puberty, the pituitary gland releases gonadotropins in order to stimulate testicular production of testosterone mostly at nighttime.

Male transgenics

Visit here for surgeons of gynecomastia surgery at hospitals of Goa in India. In female transgenetics, over expression of aromatase promotes the induction of hyperplastic and dysplastic changes in breast tissue. Over expression of aromatase in male transgenics caused increased mammary growth and histological changes similar to gynecomastia, an increase in estrogen and progesterone receptors and an increase in downstream growth factors such as TGF-beta and bFGF. Interestingly, treatment with an aromatase inhibitor leads to involution of the mammalian gland phenotype. Thus, although androgens do not stimulate breast development directly, they may do so if they aromatize to estrogen. This occurs in cases of androgen excess or in patients with increased aromatase activity. If anything, increased demand on surgeons of gynecomastia surgery at hospitals of Goa in India due to medical tourism may result in their expansion.


Androgen and aromatase

October 6, 2008

Most of the surgeons of gynecomastia surgery at hospitals of Delhi in India use exactly the same machines and instruments as the most advanced hospitals in the west. Estrogen effects on the breast may be the result of either circulating estradiol levels or locally produced estrogens. Aromatase P450 catalyzes the conversion of the C19 steroids, androstenedione, testosterone, and 16-a-hydroxyandrostenedione to estrone, estradiol-17b and estriol. As such, an overabundance of substrate or an increase in enzyme activity can increase estrogen concentrations and thus initiate the cascade to breast development in females and males. For example, in the more complete forms of androgen insensitivity syndromes in genetically male (XY) patients, excess androgen aromatizes into estrogen resulting in not only gynecomastia, but also a phenotypic female appearance. Furthermore, the biologic effects of over expression of the aromatase enzyme in female and male mice transgenic for the aromatase gene result in increased breast proliferation.
