A Comparative Study of Fresh versus Frozen Embryo Transfer and their Outcomes in Patients with Polycystic Ovarian Syndrome

Abstract

Background: In in vitro fertilization (IVF)/assisted reproductive technology, fresh embryo transfer is generally preferred over frozen embryo transfer (FET). Still, some research shows that FET could increase the childbirth rate which reduces the amount of ovarian hyperstimulation syndrome (OHSS) and pregnancy problems in females with polycystic ovarian syndrome (PCOS). There is a high risk of aberrant pregnancies, incorrect placentation, and other issues when a fresh embryo is transferred. They are more likely to get OHSS. Fresh embryo transfer reduces the chances to get pregnant as the stimulatory effect will be there for long time, and the endometrium is less receptive for the embryos and vice versa in the case of FET. For IVF, the transfer of fresh embryos is typically preferred over the transfer of frozen embryos. However, some research suggests that the transfer of frozen embryos may increase the live birth rate and decrease the rates of OHSS and pregnancy complications in women with polycystic ovary syndrome. One of the most prevalent endocrine illnesses in women of reproductive age is PCOS. Chronic anovulation, hyperandrogenemia, and clinical signs of hyperandrogenism are hallmarks of polycystic ovary syndrome in the absence of additional diseases such as congenital adrenal hyperplasia, androgen-producing tumors, or Cushing syndrome. Despite the fact that some patients are discovered to be clomiphene citrate (CC) resistant, CC is still the first line of treatment for anovulatory infertility caused by PCOS. Numerous treatments, such as the usage of metformin, ovarian drilling, and gonadotropin therapy, may be taken into consideration in these people. Materials and Methods: Fifty women in all ranging in age from 25 to 45 participated in the study. Half of the study participants are from Wardha, and the other half are from rural areas close to Wardha. Participants were chosen from patients who sought medical attention for issues relating to infertility. We have taken consent from all the patients with the mutual understanding that their medical is being used for a comparative study. All the patients in our study are subjected to IVF following embryo transfer. We have taken n = 50 in which all the patients are PCOS patients with AMH noticeably higher than others. Out of them, we have taken 25 patients who are allocated for fresh Day 5 transfer and 25 of them are allocated for Day 5 FET. We have collected data for a total of 50 patients and compared the β-human chorionic gonadotropin values whether it is positive or negative in each case. We have done a comparative study by comparing the results of patients undergoing fresh versus FET with their ages ranging from 25 to 45 years. Results: The data of fresh Day 5 embryo and frozen Day 5 transfer and their outcome were noted. We concluded that FET has good results compared to fresh embryo transfer.
