Correction After publication of the original article [1] it was noted that the caption of Table two was incorrect. This caption should read “Distribution of ovarian follicles depending on the type (healthy, transitional, and atretic). Small superscript letters a and b indicate significant differences in the respective ovarian follicle numbers within the various types of follicles (P < 0.05) as ...

Nicotine at the dose level of 0.3 mg/100 g body weight was administered to normal cycling mice for 15 days through oral and intraperitoneal routes. At autopsy on 16th day significant reduction in the ovarian and uterine weight was observed. Histological observations showed decrease in the number and size of Graafian follicles, corpora lutea and increase in the atretic follicles in the ovary. Th...

Background: Opioids may affect hypothalamic GnRH secretion and Hypothalamic-Pituitary- Gonad axis, resulting in reproductive disturbances. Current study investigates the effects of morphine on structure of ovary following superovulalion through morphologic/morphometric studies. Methods: Twelve young female NMRI mice were allocated into treatment and control groups. Treatment group received oral...

background: the most common metal used in the body is iron and since it may produce ros, it could potentially be a dangerous substance. objectives: regarding the side effects of nanomaterials such as nano iron particles and possibility of environmental contamination including air pollution with nanoscale iron particle, this study was designed to compare the effects of conventional iron oxide wi...

lead is an ubiquitous environmental toxin that induces a broad range of physiological biochemical, and behavioral dysfunctions. in this study, we examined the pathologic effects of lead acetate in nmri mouse ovarian tissue and the protective role of antioxidant l-cysteine, against the induced damage. we used lead acetate at a dose of 10 mg/kg, and l-cysteine at a dose of 200 mg/kg. both drugs w...

Cystic ovarian disease (COD) is an important cause of infertility in cattle, and ACTH has been involved in regulatory mechanisms related to ovarian function associated with ovulation, steroidogenesis, and luteal function. Here, we examined the localization of 11bhydroxysteroid dehydrogenase type 1 (11bHSD1) and 11bHSD2 proteins in the ovary of healthy cows and animals with spontaneous and ACTH-...

BACKGROUND A substantial number of the world population especially that of the developing countries rely on herbal products to control their fertility since ancient times. Rumex steudelii Hochst is one of the traditionally used antifertility plants in Ethiopia. Previous studies showed that the methanolic root extract of the plant had reversible antifertility effect in experimental animals. Howe...

The effects of PMSG on the mitotic activity of granulosa cells and atresia of large folicles in 24-day-old rats were examined. The results showed that the labelling index (1) decreased in atretic follicles parallel with a loss of FSH binding, and (2) increased in hypophysectomized rats treated with FSH. It is concluded that FSH stimulates granulosa cell divisions and that atresia may be caused ...

We compared the effects of exogenous insulin and porcine ST (pST) on follicular development after weaning. Crossbred primiparous sows received saline (1.5 mL i.m.; n = 9), insulin (.4 IU/kg BW s.c.; Eli Lilly Lente Iletin II; n = 10), or pST (40 microg/kg BW i.m.; n = 10) from d 1 to 5 after weaning (d 0). Ovaries were collected, the diameter of each follicle > or = 2 mm was measured, and fluid...
