Abstract
Objective
To evaluate whether there is an effect of the physician who transfers the embryos on pregnancy rates in in vitro fertilization-intracytoplasmic sperm injection (IVF-ICSI) treatment.
Methods
A total of 757 participants were analyzed between 2012 and 2017. Participants were classified according to 3 physicians who transferred the embryos: ([group 1=164 patients]; [group 2=233 patients]; [group 3=360 patients]). Baseline parameters and IVF-ICSI outcomes were compared between the groups.
Results
No differences were determined between the groups regarding the baseline parameters (age, age subgroups [20-29, 30-39, and ≥ 40 years old)], body mass index (BMI), smoking status, infertility period, cause of infertility, baseline follicle stimulating hormone, luteinizing hormone, estradiol (E2), thyroid stimulating hormone, prolactin levels, antral follicle count, duration of stimulation, stimulation protocol, gonadotropin dose required, maximum E2 levels, progesterone levels, endometrial thickness on human chorionic gonadotropin (hCG) administration and transfer days (p>0.05). The numbers of oocytes retrieved,metaphase II (MII), 2 pronucleus (2PN), transferred embryo, fertilization rate, day ofembryo transfer, the catheter effect and embryo transfer technique, and clinical pregnancy rates (CPRs) were also comparable between the groups (p>0.05).
Conclusion
Our data suggests that the physician who transfers the embryos has no impact on CPRs in patients who have undergone IVF-ICSI, but further studies with more participants are required to elucidate this situation.
