The association between contraceptive use and breast-feeding duration was investigated in 2380 women in rural Bangladesh where women usually stop breast-feeding once pregnant. Life table analysis showed that women receiving regular injections of depo medroxy progesterone acetate (DMPA) and those using non-hormonal contraception breast-fed significantly longer than women using no contraception. ...

BACKGROUND Hymenal abnormalities are most commonly a result of incomplete apoptosis of the urogenital sinus during embryology. Infrequently, however, noncongenital abnormalities of the hymen can occur that can cause significant sequelae such as severe introital dyspareunia. CASES We report on two adult women who developed severe introital dyspareunia secondary to hymenal stenosis and fibrosis...

Histologic changes associated with oral contraceptive usage have been described in the cervix, endometrium, myometrium, ovaries, breast, liver and blood vessels. Several types of lesions have been shown to occur frequently in women taking hormonal contraceptives. These include: (1) microglandular hyperplasia of the cervix; (2) endometrial gland regression and stromal decidualization (combinatio...

At present, the management of non-organ confined prostate cancer, whether it is a recurrence or metastasis, continues to evolve based on prostate cancer detection using prostate-specific antigen and the development of medications as alternatives for the classical orchiectomy, which induced irreversible implications for quality of life. Diethylstilbestrol therapy was associated with cardiovascul...

Venous thromboembolic events (VTEs) represent a serious complication related to hormonal contraception and hormone replacement therapy (HRT). Evidence on hormonal contraceptive- and HRT-related VTEs is derived almost exclusively from observational studies and points to a 2- to 6-fold increased relative risk of VTEs with either therapy. Oral contraceptive pills that contain third-generation prog...

OBJECTIVE To evaluate the effects of estrogen treatment in combination with gestrinone on an experimental rat model of endometriosis. METHODS Uterine transplants were attached to the peritoneum of female Wistar rats via a surgical autotransplantation technique. The implanted area was measured during the proestrus phase and after hormonal treatment. We performed morphometric analysis and exami...

Hormonal male contraception clinical trials began in the 1970s. The method is based on the use of exogenous testosterone alone or in combination with a progestin to suppress the endogenous production of testosterone and spermatogenesis. Studies using testosterone alone showed that the method was very effective with few adverse effects. Addition of a progestin increases the rate and extent of su...

The exact mechanism of carcinogenesis is unknown, although it is believed to involve a combination of dietary, environmental, genetic, lifestyle and hormonal causes. Prostate cancer is main problem of men, and it is believed that prostate cancer is the hormonal imbalance of the testosterone but now it has been proved clinically that estrogen hormone imbalance is also involved in the prostate ca...

CONTEXT The development of a safe and effective reversible method of male contraception is still an unmet need. OBJECTIVE Evaluation of suppression of spermatogenesis and contraceptive protection by coadministered im injections of progestogen and testosterone. DESIGN Prospective multicentre study. SETTING Ten study centers. PARTICIPANTS Healthy men, aged 18-45 years, and their 18- to 38...

Here, we investigate changes in women's facial masculinity preferences across pregnancy and the post-partum period. The majority of previous research demonstrating changes in women's masculinity preferences has examined the impact of hormonal variation across the female menstrual cycle. Hormonal changes experienced during pregnancy and the post-partum period, critical periods in women's reprodu...
