When infertility is caused by a male factor, cases to be treated range from low sperm count in the ejaculate -which also influences sperm motility and morphology- to cases where sperms have to be collected directly from testicles due to obstructive reasons (bilateral agenesya of deferent ducts, vasectomy, blockage in seminal ducts, etc.) or secretory problems (limited production of sperm at germline, infections, cancer, etc.). This method of sperm collection makes the prediction of pregnancy outcome difficult since the viability of most of this sperm is altered and, thus, its capacity to create a healthy embryo reduced.
With the purpose of increasing the chance of success rates in the above cases, IMFER has implemented IMSI - Intracytoplasmic Morphologically-Selected Sperm Injection, a high-resolution imaging system that allows to select non altered sperms and improve live birth rates in assisted reproduction. IMFER takes the lead in using this most innovative technique, so becoming one of the first centres in using this technology in Spain.
