Background: For more than four decades clomiphene citrate has been the first line of the treatment for ovulatory disorders. The aim of this study was to compare the effects of letrozole and clomiphene citrate on ovulation and pregnancy rate in patients with polycystic ovary syndrome. Methods: In this prospective double-blind study, 100 patients with polycystic ovary syndrome were randomized int...

OBJECTIVE This study aimed to compare two methods of treatment of infertility with gonadotropin with laparoscopic ovarian electrocauterization in patients with clomiphene citrate-resistant polycystic ovary syndrome (PCOS). METHODS A number of 104 nulipara patients with polycystic ovary syndrome, who were resistant to clomiphene citrate were randomly assigned to two groups. One group received ...

OBJECTIVE To compare the effectiveness of an electrocautery strategy with ovulation induction using recombinant follicle stimulating hormone in patients with polycystic ovary syndrome. DESIGN Randomised controlled trial. SETTING Secondary and tertiary hospitals in the Netherlands. PARTICIPANTS 168 patients with clomiphene citrate resistant polycystic ovary syndrome: 83 were allocated elec...

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...

Clomiphene citrate (a nonsteroidal oestrogen antagonist) has been used for ovarian stimulation since its discovery in the late 1950s and continues to have an important role in fertility treatment. Currently, follicle-stimulating hormone (FSH) is used in mild ovarian stimulation either by itself or in combination with clomiphene citrate. Required doses of FSH vary considerably, depending on whet...

INTRODUCTION Polycystic ovarian syndrome (PCOS) is the main cause of anovulatory infertility. Various combination of drugs have been tried to induce ovulation in PCOS patients with varied result. So, this study was planned to compare the effect of bromocriptine combined with Clomiphene Citrate and Clomiphene Citrate alone, in patients of polycystic ovarian syndrome with normal prolactin level. ...

THE aetiology of anencephaly and/or spina bifida (neural tube defects) is still obscure. Most investigators are now agreed on a multifactorial causation with an important genetic factor and a substantial environmental component. The genetic factor is probably polygenic, but the mechanism by which it acts remains unknown. Recently, drugs that stimulate ovulation, particularly clomiphene, have be...

Investigations into the effect of clomiphene citrate stimulation on endometrial differentiation were retrospectively performed in the mid-luteal phase on 21 patients undergoing ovulation induction prior to artificial insemination. A high incidence of irregular endometrial development was seen using morphological and morphometric criteria; in addition, increasing stromal oedema after clomiphene ...
