Polycystic ovarian syndrome (PCOS) is the most prevalent endocrine pathology seen among women of reproductive age. The objective of the study is to investigate the impact that ethnic background has on pregnancy outcomes, including live birth rates in infertile women with PCOS going through IVF compared to women without PCOS. Retrospective cohort study in an academic IVF center. This study used a coded REDCap data set of 486 women, 18-45 years of age who underwent IVF and embryo transfer between 1/1/2010 and 12/31/2015 at an academic IVF Center after IRB approval (IRB 2015-0623). Patients underwent their 1st IVF cycle following progestogen withdrawal (norethindrone acetate) using GnRH agonist or antagonist protocols with mixed gonadotropins and demographic data, including race and ethnicity was obtained. Data collected during the IVF process included peak estradiol, number of mature oocytes, fertilization rate, number of top quality embryos on Day 3 of development, number of embryos transferred, implantation rate, clinical pregnancy rate, live birth rate, clinical miscarriage rate, and ectopic pregnancy rate. In women, whose pregnancy resulted in a live birth, additional maternal and neonatal variables were collected, including estimated gestational age (EGA) at delivery, mode of delivery, and weight at birth. Using R analytics software, data was analyzed using logistic regression and linear models. For logistic regression, the estimated coefficient was the log-odds-ratio. A significant p value was considered <0.05. Of the 486 initial women, 360 women were included in the final analysis. Only women with known/reported ethnicity were included. Not Hispanic is the referent cohort for ethnicity and non-PCOS is the referent group when comparing PCOS status. There was no significant difference found for implantation rate (p=0.53) and pregnancy rate (p=0.99) when comparing women without PCOs with the women with PCOS. When taking into account the ethnicity factor in PCOS and the women who conceived and had a live birth, there was no significant difference between being Hispanic with PCOs and the referent non-Hispanic group. However, when evaluating women who started the IVF cycle, women with PCOS are less likely to have a pregnancy that leads to a live birth compared to women without PCOS (p=0.046). Being Hispanic by itself does not seem to affect live birth (p= 0.81). Hispanic women with PCOS have the same probability of having a vaginal delivery compared to the referent group (p=0.935). Women with PCOS are more likely to deliver ∼2 weeks earlier than non-PCOS patients (p=0.038). Being Hispanic and having PCOS did not affect the EGA at delivery (p= 0.83) or affected fetal weight compared to the referent group (p=0.58). This pilot study did not find a significant difference in most of the variables studied comparing Hispanic PCOS women with non-Hispanic women without PCOS. However, further studies with a larger number of subjects are needed to assess the impact of ethnicity and PCOS on IVF pregnancy outcomes.
