background: poor ovarian response to controlled ovarian stimulation is one of the most important interest points in assisted reproduction. mild ovarian stimulation seems to be preferable to high dose of fsh regimens in women with a history of poor ovarian response in previous protocol. clomiphene citrate and letrozole alone or in combination with fsh have been used in mild ovarian stimulation p...

The management of poor responders in IVF cycles is extremely controversial due to their inadequate response to controlled ovarian hyperstimulation.. A low ovarian response may be idiopathic or may be associated with many different factors including age, diminished ovarian reserve, endometriosis and prior ovarian surgery, and a reported incidence 9-24% of IVF patients. Several strategies have be...

background: the ability of the ovary to respond to exogenous gonadotrophin stimulation and development of several follicles is essential in assisted reproductive technology. neither age and regularity of menses nor follicular phase fsh and estradiol concentrations are reliable predictors of ovarian response. day 3 serum inhibin-b level, during induction ovulation, has been proposed as a predict...

background: despite extensive progress in ivf techniques, one of the most difficult problems is the variability in the response to controlled ovarian hyperstimulation (coh). recent studies show the effects of individual genetic variability on coh outcome. objective: to evaluate the correlation between lhβ g1502a polymorphisms in exon 3 of the lh gene and ovarian response to coh. materials and m...

objective: to compare the pregnancy outcomes achieved by in vitro fertilization (ivf) between minimal stimulation and conventional antagonist protocols in poor ovarian responders (pors). materials and methods: in this randomized controlled trial, 77 pors undergoing ivf were selected and divided into two groups. first group was the minimal stimulation group (n = 42) receiving 100 mg/day clomiphe...

background: microdose flare-up gnrh agonist and gnrh antagonist have become more popular in the management of poor ovarian responders (por) in recent years; however, the optimal protocol for por patients undergoing in vitro fertilization has still been a challenge. methods: in this observational study design, two hundred forty four poor ovarian responders were retrospectively evaluated for thei...
