By using immunohistochemistry and in situ hybridization, we have demonstrated that the nitric oxide (NO)-synthesizing enzyme NO synthase is present in gonadotrophs and in folliculo-stellate cells of the anterior pituitary gland of male and female rats. A marked increase in levels of NO synthase protein and mRNA was observed after gonadectomy. In vitro studies on dispersed anterior pituitary cel...

Women's preferences for several male traits, including voices, change over the menstrual cycle, but the proximate causes of these changes are unknown. This paper explores relationships between levels of estradiol, progesterone, luteinizing hormone, follicle stimulating hormone, prolactin, and testosterone (estimated using menstrual cycle information) and women's preferences for male vocal mascu...

UNLABELLED Lesions of anogenital mammary-like glands are rare, and only 44 female cases have been reported. Herein, we describe a particularly rare case of phyllodes tumor of anogenital mammary-like glands in a 41-year-old male presenting anal bleeding. Papillectomy was performed. The excised tumor was circumscribed in shape, and after it was sliced into sections, it was noted that there were l...

The present study was aimed at evaluating the antifertility effect of phyllanthus amarus extract in male wistar rats. The body and organ weights, cauda epididymal sperm parameters, serum levels of male reproductive hormones and fructose were assessed. Daily oral doses of the extract were administered to each animal in three different test groups for 28 consecutive days. Results show significant...

Pituitary tumors are benign that occur in the pituitary gland with a presentation of 10% all intracranial tumors. If size tumor is > 1 cm, called macroadenoma, large will have mass effect so there an emphasis on area and its surroundings. This manifest hyposecretion hormones produced pituitary. We report case 57-year-old male complaints decreased vision since 3.5 months. The patient had prev...

BACKGROUND Prostate carcinoma is among the most common solid tumors to secondarily involve the male breast. Prostate specific antigen (PSA) and prostate-specific acid phosphatase (PSAP) are expressed in benign and malignant prostatic tissue, and immunohistochemical staining for these markers is often used to confirm the prostatic origin of metastatic carcinoma. PSA expression has been reported ...

The purpose of this study was to evaluate whether experimental exposure of pregnant sheep to a mixture of environmental chemicals added to pasture as sewage sludge (n = 9 treated animals) exerted effects on fetal testis development or function; application of sewage sludge was undertaken so as to maximize exposure of the ewes to its contents. Control ewes (n = 9) were reared on pasture treated ...

Although only recently Punica granatum (pomegranate) has been acclaimed for its health benefits, this fruit has long been cultivated and consumed, as a fresh fruit or in the form of beverage, especially in the Mediterranean region. In the present study, the antioxidant effects of the methanolic extract of pomegranate peels (MEPP) and pomegranate juice (PJ) were evaluated in normal male rats. Al...

Juvenile hormone levels and adult diet have important effects on the attractiveness and competitiveness of male Anastrepha suspensa (Loew) (Caribbean fruit fly). Because the success of the sterile insect technique requires the release of males that can compete in the wild, these effects are of crucial importance. Laboratory and field cage experiments were conducted to compare male sexual perfor...
