The internal reproductive organs of Cosmoclopius nigroannulatus males and females are described, illustrated and measured. No significant difference was registered among immature and reproductive structures of males and their aspect was also similar. However, in females noteworthy differences both in size and aspect were found.

Reproductive organs in female mice are susceptible to exposure to estrogenic substances especially during development. In the present study, C57BL/6J female mice were exposed to the synthetic estrogens ethinylestradiol (EE2) or diethylstilbestrol (DES), 10-100 or 6.7-67 microg/kg bw, respectively, in utero from day 10 to 18 of pregnancy, and their effects were analyzed at 30 and 40 days of age....

The XIV Workshop on the Development and Function of Reproductive Organs was held in Rome, from 14-17 September, 2008, at the Congress Centre of the University of Tor Vergata of Villa Mondragone (Rome, Italy). The Workshop was conceived to be a survey of the events from the formation of the gamete precursors, the primordial germ cells, to the development of the preimplantation embryo through fem...

Male reproductive disorders that are of interest from an environmental point of view include sexual dysfunction, infertility, cryptorchidism, hypospadias and testicular cancer. Several reports suggest declining sperm counts and increase of these reproductive disorders in some areas during some time periods past 50 years. Except for testicular cancer this evidence is circumstantial and needs cau...

Present investigation was planned to evaluate the therapeutic effectiveness of chelating agents against vanadium intoxication on blood and reproductive organs of rats. Male and female albino rats were injected vanadyl sulphate (7.5 mg/kg, po, for 21 days, 5 days in a week). Chelating agents tiron (T) alone and in combination with lipoic acid (LA), vitamin E (vit E) and selenium (Se) were given ...

Background: Xanthogranulomatous inflammation of the female reproductive organs is a rare chronic inflammation. In most reported cases, lesion was limited to endometrium and fallopian tubes. Here, we report two cases xanthogranulomatous myometrium with history endometrial biopsy. Case Reports: myometrial destroyed myometrium. This developed into surrounding pelvic organs, resulting in uterine pe...

This article analyzes deaths and hospital discharges involving cancer of the reproductive organs in Costa Rica during the period 1956-1969. The focus in on breast, prostate, and uterine cancer, since these three types account for virtually all of the known cases. It is noted that while rates of breast and prostate cancer are very low in Costa Rica, very high rates of uterine cancer have been re...

Global ablation of INSL3 hormone or its receptor RXFP2 in male mice results in cryptorchidism and infertility. Using novel LacZ knock-in Rxfp2 allele we demonstrated a strong expression of this gene in postmeiotic germ cells. RXFP2 was expressed in embryonic and neonatal gubernaculum. No RXFP2 expression was detected in cremaster muscles in adult mice. We produced a floxed allele of Rxfp2 and t...

A 5-day Hershberger assay, a 20-day pubertal male assay, a one-month oral administration study and a reproductive toxicity study were carried out using an antiandrogenic chemical, flutamide (FL). The effects of FL were as follows: weight decrease in male reproductive organs such as the prostate and seminal vesicles were observed at ≥0.6 mg/kg/day as the most sensitive parameter in the Hershberg...
