Estimation of Fertilization Rate, Implantation Rate, Pregnancy Rate and Live Birth Rate in Intracytoplasmic Sperm Injection in Association with Number of Attempts and Sperm Morphology.

Infertility is a growing health problem. It affects relatively large number of couples both globally as well as in India. Fertility treatment registers suggest that infertility is on increase. With the advancement in the knowledge and technology about the In Vitro fertilization (IVF) process, In Vitro fertilization success rates are improving over the time. In many cases of male-factor infertility, Intracytoplasmic sperm injection (ICSI) is the recommended treatment. The aim of this study was to estimate fertilization, implantation and pregnancy rates in ICSI cycles in association with number of attempts and sperm morphology. A total of 250 IVF-ICSI cycles were performed at a Fertility Center in Jaipur, Rajasthan, India. This cohort study was performed during 2013 to 2015. The differences in the outcomes of ICSI in association with sperm morphology and number of ICSI attempt were evaluated. Significantly higher mean was observed in fertilization rate and live birth rate with ≥5% sperm morphology 79.63% vs. 71.46% and 20% vs. 13.9% respectively). Significantly higher mean implantation rate and clinical pregnancy rate (CPR) and live birth rate were observed with attempt 3 as compared to 1 and 2 attempts. IVF success rates are improving over the time as knowledge and technology are advancing. Sperm morphology and number of attempt affect the ICSI outcomes.
