The relationship between embryo quality assessed using routine embryology or time–lapse videography and serum progesterone concentration on the day of ovulatory trigger in in vitro fertilization cycles

Conclusions EP/follicle ≥14 mm (>0.42 nmol/L/follicle) adversely affects embryo implantation in women aged ≥35 years, but not <35 yrs. However, no adverse features were seen in the embryos from these affected cycles in terms of morphological appearance, abnormal patterns of cleavage, or morphokinetic timings.
