Aneuploidy incidence in embryos from patients with low and high serum basal FSH, stratified according to maternal age

	Overall, n = 1749		Pre-AMA (< 35 years), n = 198		AMA (≥ 35 years), n = 1551
	Low bFSH	High bFSH	Low bFSH	High bFSH	Low bFSH	High bFSH
Euploid	41.56%, 372/895	36.30%, 310/854	60.60%, 60/99	46.46%, 46/99	39.04%, 303/776	35.22%, 273/775
Aneuploid	58.43%, 523/895	63.70%, 544/854	39.39%, 39/99	53.53%, 53/99	60.95%, 473/776	64.77%, 502/775
p	0.02		0.04		0.12

Notes: High and low basal FSH (bFSH) values are those higher and lower than the group median, respectively. p values refer to differences in euploid/aneuploid incidence between embryos from patients with low and high bFSH in three different maternal age groups (overall, pre-AMA and AMA)
