Abstract

Objective: The study aimed to evaluate whether singleton live births (at 0, 1, 6, 12, and 24 months) following intracytoplasmic sperm injection (ICSI) using sperm of different origins (ejaculated or non-ejaculated sperm) are associated with the growth and development of children born.

Methods: This was a retrospective cohort study conducted at a single center from January 2016 to December 2019. Follow-up data of the children were obtained from the Jiangsu Province Maternal and Child database. A total of 350 singleton live births after fresh embryo transfer (ET) with ICSI were included. Based on the origin of the sperm, the patients were divided into two groups: the ejaculated group (n = 310) and the non-ejaculated group (n = 40). Propensity score matching was used to control for multiple baseline covariates, resulting in 80 singleton live births (ejaculated sperm) matched to 40 singleton live births (non-ejaculated). The non-ejaculated group was further divided into two subgroups: the PESA group (n = 23) and the TESA group (n = 17). The primary outcome of the study was the growth and development of children. Secondary outcomes included the 2PN rate, high-cleavage embryo rate, blastocyst formation rate, and others.

Results: After matching parental age, BMI, occupation, and maternal serum AMH level, there was no significant difference found in the growth and development of children between the non-ejaculated and ejaculated group or the PESA group and TESA group, respectively. However, the 2PN rate and the blastocyst formation rate were higher in the ejaculated group compared to the non-ejaculated group (91.02 and 85.45, P = 0.002) and (67.37 and 56.06, P = 0.019), respectively. The high-quality cleavage embryo rate was also higher in the TESA group compared to the PESA group (85.06 and 65.63, P = 0.001).

Conclusion: This study suggests that there are no significant differences in the growth and development of children born following ICSI using sperm of different origins (ejaculated or non-ejaculated). For nonobstructive azoospermia (OA) patients, sperm derived from the testis may be more effective than derived from the epididymis. However, due to the limited sample size of the non-ejaculated group in this study, further investigations with larger sample sizes are needed to validate these findings.

Keywords: Intracytoplasmic sperm injection, ejaculated, non-ejaculated, growth, development, non-obstructive azoospermia.
