Abstract

OBJECTIVE:

To investigate the effects of body mass index (BMI) on assisted reproductive outcomes with the freeze-all strategy for patients with polycystic ovary syndrome (PCOS).

DESIGN:

Retrospective cohort study.

SETTING:

Tertiary care academic medical center.

PATIENT(S):

A total of 3,079 women with PCOS across different BMIs at our institution from January 2015 to May 2017 were stratified into cohorts.

INTERVENTION(S):

None.

MAIN OUTCOME MEASURE(S):

Implantation rate, clinical pregnancy rate, early miscarriage rate, and live birth rate.

RESULT(S):

The live birth rate was most favorable in underweight (BMI < 18.5 kg/m2) and normal weight cohorts (18.5 ≤ BMI < 25 kg/m2) and progressively decreased as BMI increased. Moreover, the obese cohort (BMI ≥ 30 kg/m2) of patients with PCOS who had frozen ET cycles had a relatively high early miscarriage rate.

CONCLUSION(S):

The live birth rates are highest in underweight and normal weight patients with PCOS undergoing IVF with the freeze-all strategy. Furthermore, there is a progressive and statistically significant decrease in the live birth rate and an increase in the miscarriage rate in obese patients with PCOS.
