Objective(s): To benefit from reproduction and deal with challenges in the environmental conditions, animals must adapt internal physiology to maximize the reproduction rate. Maladaptive variations in the neurochemical systems and reproductive system can lead to manifestation of several significant mammalian reprocesses, including mammalian ovarian lifespan. RFamide-related peptide (RFRP, Rfrp)...

background: this study was undertaken to evaluate the role of day 3 fsh/lh ratio and day 3 lh level as predictors of ivf cycle outcomes. methods: this prospective observational study was undertaken in the ivf and reproductive biology centre and lok nayak hospital, affiliated to maulana azad medical college, in new delhi, india. the study included 105 women who underwent controlled ovarian hyper...

objective: the study assessed the efficacy of low dose ketoconazole in addition to clomiphene citrate ( cc) and hmg on ovulation induction. materials and methods: a double blind, randomized, clinical trial was performed on fifty infertile patients with pcos who had failed to respond to a daily dose of hmg and 100 mg cc for controlled ovarian hyperstimulation in vali-e-asr reproductive health re...

Gynecological diseases such as endometriosis, adenomyosis and uterine fibroids, and gynecological cancers including endometrial cancer and ovarian cancer, affect a large proportion of women. These diseases are estrogen dependent, and their progression often depends on local estrogen formation. In peripheral tissues, estrogens can be formed from the inactive precursors dehydroepiandrosterone sul...

Across the Western World there is an increasing trend to postpone childbearing. Consequently, the negative influence of age on oocyte quality may lead to a difficulty in conceiving for many couples. Furthermore, lifestyle factors may exacerbate a couple's difficulty in conceiving due mainly to the metabolic influence of obesity; however, the negative impacts of low peripheral body fat, excessiv...

The development of malignant tumors is constituted by different immunological components. Interleukin (IL)-1 receptor antagonist (RA) is known to be critically involved in the carcinogenesis of different malignant solid tumors. Polymorphism of a specific gene can have an important effect on gene transcription, the stability of the mRNA, or the quantity and activity of the resulting protein. In ...

Background: Understanding ovarian folliculogenesis is critical to the study of fertility and in the development of fertility techniques as well as contraception. Mares and women share striking similarities in ovarian folliculogenesis, and in insulin resistance and obesity syndromes. The effects of insulin resistance and obesity on follicular development and the surrounding endocrinology and gen...

Current evidences indicate that the fallopian tube plays a major role in the pathogenesis of epithelial ovarian cancer (EOC). Salpingectomy represents a novel and potentially effective risk-reducing option. In this study, there were 1822 patients diagnosed and treated for EOC or primary peritoneal cancer (PPC) at Department of Gynecologic Oncology, Tianjin Medical University Cancer Institute an...

BACKGROUND The investigational endeavors of ovarian cryopreservation await the clinical experience of auto- or xenotransplantation, in vitro maturation of thawed primordial follicles, their in vitro fertilization and embryo transfer. Although promising, this experience is not yet available. Moreover, the risk of possible reimplantation of malignant stem cells with the thawed cryoperserved ovary...

The effect of seven diseases on culling was measured in 7523 Holstein cows in New York State. The cows were from 14 herds and had calved between January 1, 1994 and December 31, 1994; all cows were followed until September 30, 1995. Survival analysis was performed using the Cox proportional hazards model to incorporate time-dependent covariates for diseases. Different intervals representing sta...
