The Aim of This Study is to Determine the Incidence of Alterations in Fluorescent In Situ Hybridisation (FISH) of Spermatozoa and to Evaluate the Efficacy of the Use of Annexin Columns (MACS®) in Patients With Altered FISH Undergoing In Vitro Fertilisation Techniques

250 petitions for FISH of spermatozoa were requested, determining the total and particular incidence in each of the indications collected. The effect of annexin columns was evaluated in 10 couples with altered FISH. In each of the couples, oocytes were pseudo-randomised to the control group and MACS®. All couples received experimental treatment. Mixed logistic regression model were adjusted to evaluate the effect of MACS® on the response variables studied.
