Evaluation of frozen embryo transfer results with regard to different indications

Frozen embryo transfer (FET) is a common practice throughout the world in order to increase cumulative pregnancy rates. Although there are two different types of embryo freezing technics, vitrification process stands more common due to better outcome compared to slow freezing. We analyzed couples undergoing intracytoplasmic sperm injection (ICSI) and fresh embryo transfer, and subsequently frozen embryo transfers. For this purpose, A total of 258 couples with the diagnosis of endometriosis, polycystic ovary, poor ovarian response, tubal factor, unexplained infertility and male factor were examined. The main purpose was comparing people who have infertility indications with FET clinic results. Women who are under the age of 40 with normal normal uterine cavity were included. The average age of men and women and the number of frozen embryos transferred were similar among groups. FET results for patients who has endometriosis after clinic pregnancy was %29.6 (8/27), for patients who has polycystic ovary syndrome is %30.2 (13/43), for patients who has poor responder was %28.9 (11/38), for patients who has tubal factor %34.2 (12/35), for patients who has unexplained infertility %28.2 (11/39) and for patients who has male factor %28.9 (22/76). There was no statistically significant differences in clinical pregnancy among groups. As a result, clinical pregnancy rates were similar in different groups with diffrent infertility etiologies. After the ovulation induction, use of excessive embryos in coming cycles of frozen embryos will increase cumulative pregnancy results. Laboratories that work on assisted reproductive techniques must have an experienced crew who can freeze embryos and necessary equipment available.
