Pregnancy results after intracytoplasmic sperm injection-embryo transfer in patients with infertility due to non-obstructıve azoospermia and oligoasthenoteratozoospermia.

This study evaluated pregnancy results after fresh and frozen embryo transfer in males with infertility due to non-obstructive azoospermia and oligoasthenoteratozoospermia. In this retrospective study, a total of 801 embryo transfer cycles were followed up, including 423 fresh embryo transfers and 378 frozen embryo transfers in which intracytoplasmic sperm injection (ICSI) was performed because of male infertility. This study included females aged 28-38 years without uterine, endometrial, ovarian and tubal abnormalities and with regular menstrual cycles (n=801), and males aged 28-38 years with non-obstructive azoospermia and oligoasthenoteratozoospermia. Descriptive statistical methods and the independent t-test were used in the comparison of two groups with normal distribution, the Mann-Whitney U test was used in the comparison of two groups without normal distribution, and the Chi-square test was used to compare categorical variables. There were no statistically significant differences between the fresh embryo transfer group and frozen embryo transfer group in terms of rates of pregnancy, biochemical pregnancy, clinical pregnancy, live birth rate, and abortion rate. There was no difference between fresh embryo transfer and frozen embryo transfer in terms of pregnancy results in couples with non-obstructive azoospermia and oligoasthenoteratozoospermia as male infertility factor.
