NCT Number: NCT03659812
The aim of this study is to analyse the efficacy of MACS technique for the selection of spermatozoa and its effects on implantation, pregnancy and miscarriage rate. This study will be performed by two IVI clinics (IVI Sevilla and IVI Madrid) with the purpose of finding new techniques that allow us to better select spermatozoa and improve the results of assisted reproduction techniques.

Inclusion criteria
MACS is a technique that allow us to tag and detect apoptotic spermatozoa. These apoptotic spermatozoa have phosphatidylserine in their membranes, so we add magnetic beads with Annexin V, which binds specifically to phosphatidylserine. The spermatozoa are then tagged and can be retained in a magnetic field, allowing us to collect just the non-apoptotic spermatozoa.
Time frame: Ultrasound examination is performed 5 weeks after artificial insemination. Pregnancy rate is calculated during the phase of data analysis.
The number of pregnancies confirmed by ultrasound divided by the number of artificial insemination cycles. Pregnancy is confirmed by ultrasound examination.
Time frame: The beta hCG analysis is performed 15 days after artificial insemination. Implantation rate is calculated during the phase of data analysis.
The number of positive results of beta human chorionic gonadotropin (hCG) test divided by the number of artificial insemination cycles. Implantation is confirmed through the analysis of beta hCG in blood.
Time frame: Live births are assessed at delivery (end of pregnancy period). Live birth rate is calculated during the phase of data analysis
The number of live births divided by the number of artificial insemination cycles
Time frame: This parameter is assessed when preparing the sample for artificial insemination (one hour before artificial insemination).
Concentration of sperm cells in sperm sample before and after applying the MACS technique
Time frame: This parameter is assessed when preparing the sample for artificial insemination (one hour before artificial insemination).
Proportion of sperm cells with progressive motility (according to World Health Organisation 2010 criteria) before and after applying the MACS technique
Time frame: This parameter is assessed when preparing the sample for artificial insemination (one hour before artificial insemination).
Proportion of sperm cells with normal morphology (according to World Health Organisation 2010 criteria) before and after applying the MACS technique
Time frame: This parameter is assessed when preparing the sample for artificial insemination (one hour before artificial insemination).
Proportion of live sperm cells before and after applying the MACS technique
Time frame: This parameter is assessed when preparing the sample for artificial insemination (one hour before artificial insemination).
