Abstract
BACKGROUND: Intra-Cytoplasmic Sperm Injection (ICSI) has revolutionized the reproductive outcomes for couples with male factor infertility. Especially in azoospermic men, use of ICSI with surgically retrieved testicular sperm has helped them have their own biological child. However, considering the immature nature of testicular sperm safety of testicular sperm has been debated. AIMS: To compare reproductive outcomes, neonatal outcomes and the incidence of congenital malformations in children born after intracytoplasmic sperm injection (ICSI), using different sperm origins. SETTINGS AND DESIGN: This is a retrospective study in which a total of 989 participants were enrolled. Study group (Testicular Sperm Aspiration (TESA) ICSI group) had 552 couples with female partners aged ≤37 and had self gamete cycles. ICSI cycles with ejaculated sperm (EJS) acted as the control group. MATERIALS AND METHODS: All male patients underwent surgical sperm retrieval and all the women underwent controlled ovarian stimulation and transvaginal oocyte retrieval and Ovum Pick Up (OPU) as per the standard operating procedures of the clinic. Frozen embryo transfer with two good-grade blastocysts, which had shown 100% survival, were transferred in subsequent cycles. STATISTICAL ANALYSIS USED: The Student's t-test was performed for age distribution; odds ratio was performed to find the confounding factors. RESULTS: Embryonic and reproductive outcomes were comparable and not statistically significant in the study and control groups. Incidence of congenital anomalies was observed in singleton live births and twin live births in both the TESA-ICSI group and the EJS-ICSI group, but the difference was not statistically significant. CONCLUSIONS: Our study revealed that congenital malformations in children born out of ICSI using testicular sperm and EJS were similar; no difference was observed in miscarriages between the testicular sperm-ICSI and EJS-ICSI group. Our data suggests that surgical sperm retrieval in couples with male factor infertility does not alter their reproductive outcome.
