ABSTRACT

Objective: To evaluate if the manipulation of gametes with a flow cytometry sorter has a negative effect on the key performance indicators (KPI´s).
Materials and Method: Descriptive and retrospective analysis, in couples undergoing In a Vitro Fertilization (IVF) by ICSI, with sperm selection, using a flow cytometry sorter for sex selection. The study was conducted at the New Hope Fertility Center in Guadalajara and Mexico City, from June 2014 to August 2017. The results were compared with a randomly group without a flow cytometry sorter. KPI´s were evaluated; normal fertilization rate, abnormal (1PN, ≥3 PN), failed fertilization, ICSI damage rate, cleavage rate, blastocyst development rate, implantation rate (cleavage and blastocyst-stage) and live birth rate. A Student's t-test was made for two samples considering significant differences with p ‹ 0.05.
Results: 150 cycles were evaluated. Group 1: ICSI with sperm selection by a flow cytometry sorter (n = 40); Group 2: ICSI without sperm selection (n = 110). Observing with statistical significance a decreased of the KPI´s of Group 1: failed fertilization rate (1.6%), blastocyst development rate (17.4%), implantation rate (cleavage-stage) (10%), implantation rate (blastocyst-stage) (14.2%) and live birth rate (14.5%).
Conclusions: The manipulation of gametes with the flow cytometry sorter, has a negative effect on the assisted reproductive technology KPI´s; specifically, in the blastocyst rate, blastocyst implantation rate and live birth rate.
