Summary

This is a prospective and multicentric observational study to determine the real mono-bifollicular development rate that is obtained under normal care conditions following ovulation induction (OI) treatment with follitropin-alpha filled by mass prescribed in accordance with standard practice.

Detailed description

In women with infertility due to anovulation, the main purpose of ovulation induction (OI) consists in inducing the mono or bifollicular and the subsequent ovulation in order to achieve pregnancy. The availability of recombinant gonadotropins obtained using genetically engineered techniques has meant a decisive and clear pharmacological advancement. Use of recombinant human follicle stimulating hormone (r-hFSH) offers a greater effectiveness (greater number of follicles/ ovocytes and a higher pregnancy rate) and efficiency (fewer number of blisters, fewer stimulation days; fewer number of cancellations and complications) in programmed coitus and artificial insemination like in-vitro fertilisation (IVF)/intra cytoplasmic sperm injection (ICSI) techniques. Further advances in obtaining better products for ovarian stimulation has led to production of a recombinant FSH (follitropin alpha) filled by mass preparation. This hormone becomes the most consistent and precise gonadotropin due to improvements in its quantification process. Today, despite having accurate and modern tools for ovulation induction, in daily practice, doctors continue to "fight" against two old problems of assisted reproduction: multiple pregnancies and ovarian hyperstimulation syndrome (OHSS). Application of assisted reproduction techniques (ARTs) and the use of medication that induce ovulation, risk producing gestations and multiple births with a higher frequency than those observed in spontaneous gestations. One of the facts that result in the appearance of such problems is the high incidence of polycystic ovarian syndrome among the population of women who are infertile due to anovulation. These subjects are especially sensitive to ovarian stimulation, which leads to multiple follicular development, a higher risk of hyperstimulation and higher rates of multiple pregnancies. Therefore, it seems clear that the search for developing mono or bifollicular cycles is important in ovarian induction cycles, for the purpose of preventing the above mentioned multiple pregnancy problems and the risk of OHSS. The intent of this study was to figure out the real mono-bifollicular development rate that is obtained under normal care conditions following OI treatment with follitropin alpha filled by mass prescribed in accordance with standard practice. Therefore, a measure of the efficiency of the product for achieving the development of one or two follicles. Data was collected from 56 centres of the Autonomous Communities that accepted this observational study, until achieving a total of 410 ovulation induction cycles. OBJECTIVES Primary objective: * To find the real proportion of cycles with mono-bifollicular development during the provision of care involving OI with follitropin alpha filled by mass Secondary objectives: * To evaluate if the use of follitropin alpha filled by mass has other clinical benefits such as a reduction in the number of cancelled cycles, of the dosage and time required and adverse effects
