NCT01100346

Brief Summary

This is a single center, prospective, observational study on the use of Gonal-f in controlled ovarian hyperstimulation (COH) in subjects undergoing ovulation induction/ intrauterine insemination (OI/IUI) therapy across Taiwan. It has been observed in the previous studies that COH with follicle stimulating hormone (FSH) is considered as one of the positive predictors of an ongoing pregnancy. Many studies in the past have tried to predict the FSH threshold, defined as the FSH dose on the day when a follicle is \>10 mm in diameter, but no studies have been conducted to date to determine the predictive factors for a monofollicular development after COH in IUI cycles. Monofollicular growth contributes significantly to the reduction of multiple pregnancies and thus minimize the risks associated with such pregnancies. This study would provide preliminary data on the factors associated with a monofollicular development in Gonal-f treated cycles using a low dose step-up regimen.

Outcome Measures

Primary Outcomes (3)

  • Number of follicles 11-15 mm and ≥ 16 mm in diameter, estradiol (E2) levels and endometrial thickness

    On the day of hCG administration (during 24-48 hrs after the last Gonal-f injection)

  • Total dose of Gonal-f used during stimulation, threshold of Gonal-f dose (daily dose of Gonal-f when follicular growth is > 11 mm in diameter)and duration of Gonal-f treatment

    During the period of ovarian stimulation

  • Outcomes of the treatment (Pregnancy status)

    Clinical pregnancy, multiple pregnancy, miscarriage, cycle cancellation, Ovarian hyperstimulation syndrome (OHSS) and severity.

    Stimulation start to pregnancy assessment

Secondary Outcomes (1)

  • Proportion of subjects with monofollicular development

    On the day of hCG administration (during 24-48 hrs after the last Gonal-f injection)

Interventions

A starting dose of 75 IU/day subcutaneously is maintained for a period of 7 to 14 days. The follitropin alpha dose would be subsequently increased by 37.5 IU/day at weekly intervals based on the ovarian response.
