In a double-blind clinical trial, 114 subfertile men were given courses of clomiphene citrate (100 mg daily for three 10-day periods in successive months) and ofplacebo tablets of identical appearance. There were no consistent changes in sperm density. No serious adverse reactions to clomiphene were seen. Further studies are recommended on the efficacy of clomiphene in doses of 25 to 50 mg dail...

Introduction: Clomiphene, a selective estrogen receptor modulator (SERM), is drug which primarily used for the treatment of anovulatory infertility in female patients. Although as an off-label use, some authorities and physicians use this idiopathic oligoasthenospermia male Clomiphene has two isomers multiple metabolites, its cis isomer (Zuclomiphene) can be detected urine long eight months cas...

background: unovulation is the most common cause of infertility. the first line oral treatment has been clomiphene citrate. another anti-estrogen used for ovulation induction is tamoxifen. many unovulatory infertile women are resistance to anti-estrogens and need another treatment. alternative treatments are aromatas inhibitors. objective: this study was designed to compare the effectiveness of...

Background: One of the most common causes of infertility in women is ovulatory dysfunction (PCOS) and the choice of treatment is clomiphene citrate. One of the mechanism of dichotomy between the rate of ovulation and pregnancy is anti estrogenic effects of clomiphene citrate on endometrium. According to its long half life, the anti estrogenic effects probably exacerbate in consecutive cycles. W...

AIM The objective of this study was to compare the use of clomiphene citrate and letrozole in an IVF setting in which the objective was to produce only one or two embryos. Either clomiphene citrate or letrozole was used in conjunction with gonadotropins without the use of GnRH antagonists. METHODS Sixty-two patients received either clomiphene citrate or letrozole with low dose gonadotropins i...

Our objective was to examine the relationship between patient weight and the dose of clomiphene required for pregnancy so as to assess the validity of recommendations that the dose of clomiphene be limited to 100 mg. We retrospectively analysed the weight-dose relationship in 1681 clomiphene pregnancies and the relationship between dose and pregnancy, births, multiple births, number of pre-ovul...

The aim of this work was to compare the efficiency of standard intrauterine insemination (IUI) and Fallopian tube sperm perfusion (FSP) in the treatment of infertility. Ninety-six consecutive patients with infertility in 100 cycles were included in the study. Those randomized to standard IUI included 48 patients in 50 cycles [25 clomiphene citrate only and 25 clomiphene citrate/human menopausal...

Evidence • Systematic review of RCTs of antiestrogens in PCOS1: -In 3 RCTs (N = 133) that examined clomiphene (50 to 250 mg/d, 1 to 5 cycles) versus placebo, the pregnancy rate was higher with clomiphene (20% vs 3%); the number needed to treat (NNT) was 6. Live births and miscarriages were not reported. -Limitations: small sample, variable dosing and number of cycles, high dropout rate, poor ad...

BACKGROUND Luteinized unruptured follicle (LUF) syndrome is considered a cause of ovulation failure and a subtle cause of infertility. Preovulatory injection of human chorionic gonadotropin (HCG) prevents or treats LUF syndrome, but it has also occurred after the induction of ovulation with clomiphene/HMG and HCG. This study was designed for evaluation and comparison of LUF incidence in eligibl...

Seven patients with anorexia nervosa were studied, three during the acute stages of the illness, and four in whom weight gain had been achieved, but who suffered from persistent amenorrhoea of 18 to 79 months' duration.In the acute stage all patients had low serum luteinizing hormone (LH) levels which were unresponsive to clomiphene citrate. In those who had regained weight the mean basal LH le...
