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...

background: intracytoplasmic sperm injection (icsi) is an advanced technique employed in assisted reproductive clinics for treatment of infertile couples. the reproductive endocrinologists try their level best to identify factors that enhance success rate after icsi. objective: to compare estradiol progesterone ratio on ovulation induction day amongst pregnancy outcome groups following icsi. ma...

background: different protocols are used for controlled ovarian hyper stimulation (coh), but the optimal method has not yet been determined. objective: the aim of this study was to compare the outcome of controlled ovarian stimulation (cos) using clomiphen citrate (cc) plus hmg versus cc plus rfsh in intra uterine insemination cycles (iui). materials and methods: 144 women with unexplained or m...

ovarian follicle response and corpus luteum formation following induction of ovulation using gonadotropin-releasing hormone (gnrh) analogues and luteinizing hormone (lh) in bactrian camel were characterized. bactrian camels with a mature follicle (13-19.6 mm) received: 1) natural porcine lh (25 mg, iv, n = 4), 2) buserelin (20 μg, iv, n = 4) and 3) alarelin (25 μg, im, n = 4). daily ultrasonogr...

case presentation the studied patient was a 32-year-old g1p1 woman with abdominal pain who was diagnosed with a large ovarian cyst during ovulation induction, which could possibly raise the risk of ovarian torsion. she had a 2-year secondary infertility and had received three cycles of ovulation induction with letrozole 6 months earlier. an emergency laparoscopy showed large complex ovarian cys...

background: clomiphen citrate (cc) is the first line therapy for women with infertility and poly cystic ovary syndrome( pcos). however, 20-25% of women are resistant to cc and do not ovulate. objective: the objective of this study was to evaluate the efficacy of sequential treatment of metformin and incremental doses of letrozole in induction of ovulation in cases of cc-resistant pcos patients....

background: the beneficial role of cabergoline as a prophylactic agent to prevent ovarian hyper stimulation syndrome (ohss) among high-risk patients has been demonstrated in previous studies. but data for its role as a treatment for established severe ohss is still limited. we represent the treatment results of high dose oral cabergoline in management of six patients after the syndrome is estab...

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...

objective: to compare the effectiveness of letrozole and clomiphene citrate (cc) on uterine blood flow rate in patients with unexplained infertility. materials and methods: in this randomized clinical trial 90 women with unexplained infertility referred to a university clinic from january 2011- december 2013 were enrolled. thirty patients were randomized for letrozole, 30 patients for cc and 3o...
