Background The effect of smoking cigarettes is followed by diverse effects on ovaries and developing follicles but the effect of passive smoking on ovarian function is unknown. On the other hand, the ovarian response to induction is a very important step in assisted reproduction. The aim of this study is to compare ovarian response in passive smokers and non-passive smokers in an assisted repro...

background: the effect of smoking cigarettes is followed by diverse effects on ovaries and developing follicles but the effect of passive smoking on ovarian function is unknown. on the other hand, the ovarian response to induction is a very important step in assisted reproduction. the aim of this study is to compare ovarian response in passive smokers and non-passive smokers in an assisted repr...

background: this research investigated the response of vascular active factors, vascular endothelial growth factor (vegf) and angiotensin-ii (at-ii) to ovarian stimulation during 24 hours in patients with polycystic ovary syndrome (pcos). materials and methods: in this clinical trial study, 52 patients with pcos and 8 control cases were stimulated with human chorionic gonadotropin (hcg) on the ...

Background: With the recent development of recombinant gonadotropins (FSH and LH), it has become possible to further adjust the stimulation protocol according to the expected needs of the patient. In this respect, the possible beneficial role of exogenous LH activity supplementation for stimulated ART cycles has received increasing attention. According to the two-cell, two- gonadotropin theory,...

STUDY QUESTION Can predictors of low and high ovarian responses be identified in patients undergoing controlled ovarian stimulation (COS) in a GnRH antagonist protocol? SUMMARY ANSWER Common prognostic factors for high and low ovarian responses were female age, antral follicle count (AFC) and basal serum FSH and LH. WHAT IS KNOWN ALREADY Predictors of ovarian response have been identified i...

a:4:{s:10:"Background";s:689:"Ovulation is one of the most important stages in treatment of fertility. Considering the importance of this stage and the incidence of treatment failures, much effort has been made to anticipate in some way the responses of ovary to different protocols of ovulation stimulation. Some of the authentic procedure in determination of ovary response to ovulation stimulat...

Controlled ovarian stimulation (COS) in in vitro fertilization (IVF) cycles is the starting point from which couple's prognosis depends. Individualization in follicle-stimulating hormone (FSH) starting dose and protocol used is based on ovarian response prediction, which depends on ovarian reserve. Anti-Müllerian hormone levels and the antral follicle count are considered the most accurate and ...

Aims: Ovarian cancer has the worst prognosis among female genital tract malignancies, but if detected in the early stages, it is one of the most treatable malignancies. The aim of this study was to investigate the diagnostic value of tumor markers compared to ultrasound in the diagnosis of ovarian tumors. Materials and methods: In this cross-sectional-analytical study, 210 women referred to ...

Effective controlled ovarian stimulation (COS) is crucial for IVF outcome. Ovarian response to follicle-stimulating hormone, however, varies widely among women undergoing ovarian stimulation. Advance identification of patients who will elicit a poor or high response to standard treatment would be of great clinical benefit for such patients. Application of pharmacogenetics to ovarian response ma...
