BACKGROUND The objectives of this study were to determine the effectiveness the effectiveness of post-polypectomy hysteroscopic endometrial resection in preventing the recurrence of endometrial polyps in post-menopausal patients and analyse the complications and necessity of additional surgery in patients, in addition to their degree of satisfaction. METHODS A prospective longitudinal study o...

This report reviews the recent literature on the adverse effects of occupational factors on fertility and related reproductive outcomes. Few studies fulfill the criteria of good study design because of small sample size, insensitive measures of effect, selection, recall, and observation bias, weak if any control of confounding factors, bad definition of exposure, inability to analyze a dose-res...

Elevated estradiol levels are correlated with male infertility. Causes of hyperestrogenism include diseases of the adrenal cortex, testis or medications affecting the hypothalamus-pituitary-gonadal axis. The aim of our study was to elucidate the effects of estradiol treatment on testicular cellular morphology and function, with reference to the treatment regimen received. Testes samples (n = 9)...

We have examined the tissue-specific mRNA expression of ER alpha and ER beta in various bovine tissues using real-time RT-PCR. The goal of this study was to evaluate the deviating tissue sensitivities and the influence of the estrogenic active preparation RALGRO on the tissue-specific expression and regulation of both ER subtypes. RALGRO contains Zeranol (alpha-Zearalanol), a derivative of the ...

The aim of this study was to determine whether serum levels of 17beta-estradiol and progesterone are significant diagnostic tools for the confirmation of specific reproductive diseases associated with hyperestrogenism. Thirty-one adult ferrets (Mustela putorrius furo) were divided into five groups. The levels of serum 17beta-estradiol differed significantly when comparing females with ovarian t...

Urinary three estrogens (estrone, estradiol-17 [3 and estriol) in patients with advanced breast cancer before and after oophorectomy and adrenalectomy were chemically determined in an attempt to evaluate response of cancer to the surgery and its subsequent relapse. Results are as follows: 1. The existence of adrenal estrogens was evidenced indirectly in control subjects. 2. The high levels of p...

Mycotoxins produced by Fusarium plant pathogen species have harmful effects on humans and livestock by natural contamination in food and feed. Zearalenone, one of the well-known Fusarium mycotoxins, causes hyperestrogenism and toxicosis resulting in reproductive dysfunction in animals. This study investigated the occurrence of zearalenone in feedstuffs (compound feeds, feed ingredients) between...

We have examined the tissue-specific mRNA expression of ERa and ERb in various bovine tissues using real-time RT-PCR. The goal of this study was to evaluate the deviating tissue sensitivities and the influence of the estrogenic active preparation RALGRO on the tissue-specific expression and regulation of both ER subtypes. RALGRO contains Zeranol (a-Zearalanol), a derivative of the mycotoxin Zea...

Endometriosis is classically defined as the presence of endometrial glands and stroma outside of the endometrial lining and uterine musculature. With an estimated frequency of 5%-10% among women of reproductive age, endometriosis is a common gynecologic disorder. While in itself a benign lesion, endometriosis shares several characteristics with invasive cancer, has been shown to undergo maligna...

McCune-Albright syndrome is a rare genetic disorder with typical skeletal and endocrine manifestations. The disease course is complicated by recurrent fractures resulting from polyostotic fibrous dysplasia and the treatment is thus primarily directed at the reduction of the risk of fractures. However, due to the complex mechanism of the skeletal damage the standard antiporotic therapeutics are ...
