Predictive value of basal androgen levels on ongoing pregnancy rates during in vitro fertilization cycles

We aimed to evaluate the impact of elevated basal androgen levels on the endometrial receptivity. This study retrospectively enrolled 5278 fresh in vitro fertilization (IVF) cycles and sought to determine whether increased basal androgen levels are associated with adverse outcomes in regard to ongoing pregnancy rates. The results showed that the average age of our sample was 29.31 years. Almost 61.6% of all embryo transfers were with Day 3 embryos and the remaining 38.4% were with Day 5 embryos. The ongoing pregnancy rate was 56.4%. The ongoing pregnancy rates according to the various ordinal serum androgen intervals (<10.00, 10.00-19.99, 20.00-29.99, 30.00-39.99, and ≥40.00 ng/dL) were 60.12, 56.62, 58.64, 55.48, and 50.17%, respectively. The ongoing pregnancy rates were significantly lower in patients with high basal androgen levels (e40 ng/dL) (p < .05). Multivariate regression analysis showed that age, BMI, and endometrial thickness were inversely associated with basal androgen levels (p < .0001 for all). In conclusion, elevated serum basal androgen levels on cycle Day 3 before IVF is associated with reduced ongoing pregnancy rates.
