Does COVID-19 infection influence patients' performance during IVF-ET cycle?: an observational study.

OBJECTIVE

No information exists in the literature regarding the effect of coronavirus disease 19 (COVID-19) infection on subsequent n vitro fertilization (IVF) cycle attempt. We, therefore, aim to assess the influence of COVID-19 infection on IVF treatments.

DESIGN

An observational study.

SETTING

A tertiary, university-affiliated medical center.

PATIENTS AND METHODS

All consecutive couples undergoing ovarian stimulation (OS) for IVF, before and after recovering from COVID-19 infection, and reached the ovum pick-up (OPU) stage. The stimulation characteristics and embryological variables of couples undergoing IVF treatments after recovering from COVID-19 infection were assessed and compared to their IVF cycles prior to COVID-19 infection.

MAIN OUTCOME MEASURES

Stimulation characteristics and embryological variables.

RESULTS

Nine couples (seven with the female partner infection and two with the male partner) resumed IVF treatment 8-92 d after recovering from the COVID-19 infection (negative polymerase chain reaction [PCR]). No in-between cycles differences were observed in OS and embryological variables between the cycles before and after recovering from the COVID-19 infection, except for a significantly lower proportion of top-quality embryos.

CONCLUSIONS

COVID-19 infection did not affect patients' performance or ovarian reserve in their immediate subsequent IVF cycle, except for a reduced proportion of top-quality embryos (TQEs). We therefore suggest, to postpone IVF treatment for a least 3 months (duration of folliculogenesis and spermatogenesis) after recovering from COVID-19 infection, aiming to recruit healthy gametes that were not exposed to COVID-19 infection during their development.
