RANDOMIZED CONTROLLED TRIAL

BACKGROUND: This Phase IV, open-label, multicentre, randomized study (MEnTOR) compared two low-dose recombinant human follicle-stimulating hormone (r-hFSH) protocols for ovulation induction. METHODS: This study was conducted in six Middle Eastern countries between March 2009 and March 2011. Eligible women (18-37 years), with World Health Organization Group II anovulatory infertility, were randomized to receive r-hFSH (starting daily dose: 75 IU) as a chronic low-dose (CLD) (37...

BACKGROUND: Women with polycystic ovarian syndrome (PCOS) are known to have elevated circulating Anti-Müllerian hormone (AMH), which has been found to desensitize ovarian follicles to follicle stimulating hormone (FSH). The purpose of this study was to investigate the impact of high circulating AMH on ovarian responsiveness to ovulation induction with gonadotrophins in PCOS women. METHODS: This prospective observational pilot study was conducted in two collaborating Fertility Centres in the UK and Egypt...

To identify baseline characteristics related to successful ovulation induction, data were analysed from oligo- or anovulatory patients undergoing their first cycle of human recombinant FSH (r-hFSH; follitropin alfa) in a chronic low-dose (75 IU starting dose), step-up protocol in two clinical trials (n=446). Patients were grouped according to response: group A, ovulated within 14 days (75 IU follitropin alfa); group B, ovulated after 14 days (>75 IU follitropin alfa); group C, not administered human chorionic gonadotrophin (HCG) because of poor response; group D, cycle cancelled due to over-response (HCG not administered); group E, spontaneous ovulation prior to obtaining criteria for administration of HCG...

RANDOMIZED CONTROLLED TRIAL

This single centre randomized controlled trial was undertaken to compare the efficacy and safety of clomiphene citrate and low-dose recombinant FSH as first line pharmacological therapy for anovulatory infertility associated with polycystic ovary syndrome (PCOS). Seventy-six infertile patients with PCOS were randomized to receive clomiphene citrate (50-150 mg/day for 5 days) (clomiphene citrate group, n = 38) or recombinant human FSH (FSH group, n = 38) in a chronic, low-dose, step-up protocol (daily starting dose 75 IU) for up to three consecutive cycles...

OBJECTIVE: To assess the efficacy and safety in clinical practice of a low dose regimen of 50 IU of recombinant follicle stimulating hormone in induction of ovulation. DESIGN: Prospective, observational, non-comparative, open, multicentre study. SETTING: Eighty-eight infertility clinics and teaching hospital fertility units throughout Spain. POPULATION: Women with normogonadotrophic chronic anovulation (WHO group II) with or without echographic diagnosis of polycystic ovary syndrome...

Anovulation, a common cause of female infertility, is a highly curable condition. Presented here is a simple treatment-orientated diagnostic scheme. Anovulatory women with low endogenous oestradiol and follicle stimulating hormone (FSH) are treated with either pulsatile gonadotrophin releasing hormone (GnRH) or gonadotropins, and women with eu-oestrogenic anovulation (mostly with polycystic ovarian syndrome; PCOS) have first-line treatment with clomiphene citrate (CC), possibly with metformin. If CC fails, FSH is administered using a chronic low-dose protocol with small incremental dose rises...

Elevated LH concentrations are frequently encountered in patients with polycystic ovary syndrome (PCOS) and increased LH (either endogenous or superimposed through the use of HMG) may have detrimental effects on reproductive function. In spite of this, FSH-only products and HMG have been used indiscriminately for ovulation induction - on the basis that the administration of HMG to patients with PCOS, who are not receiving GnRH agonists, does not result in significant increases in serum LH concentrations as judged by daily single blood samples...

We performed a prospective study to assess the effects of a starting dose of 50 units of recombinant follicle stimulating hormone (Puregon) during gonadotrophin-releasing hormone agonist therapy (Suprecur) on follicular development in patients with clomiphene citrate-resistant polycystic ovary syndrome (PCOS). In a prospective clinical trial, 25 women with clomiphene citrate-resistant PCOS who wanted to become pregnant were treated by a low-dose step-up protocol of SC recombinant follicle stimulating hormone administration during gonadotrophin-releasing hormone agonist therapy, monitored by transvaginal ultrasonography and retrospectively by serum endocrine assays taken at each monitoring visit...

The present study compared ovarian performance and hormone concentrations, after ovulation induction, in polycystic ovarian syndrome (PCOS) patients, using recombinant human FSH (rhFSH) in low-dose step-up and modified step-down regimens. Twenty-six women with clomiphene citrate-resistant chronic anovulatory infertility were treated with rhFSH in two consecutive cycles according to two different low-dose regimens: (i) the classic chronic low-dose step-up protocol, the starting dose being 75 IU; (ii) a modified step-down protocol where the starting dose was 300 IU followed by 3 days free of treatment, then rhFSH 75 IU daily was given and stepwise dose increments were performed exactly the same as in the step-up method...

REVIEW

Chronic anovulation is probably the major cause of human infertility and is essentially associated with four distinct endocrine conditions; hyperprolactinemic anovulation, hypogonadotrophic anovulation, normo-gonadotrophic anovulation and hypergonadotrophic anovulation. Hyperprolactinaemia and microprolactinoma are frequent findings in young women and excessive prolactin secretion impairs ovarian function causing anovulatory subfertility. Dopaminergic treatment restores ovarian function and shrinks prolacinoma...
