Serum Kisspeptin (ng/mL)	IUP (n=20)	SAB (n=20)	p value	Non-pregnant (n=19)	p value
Serum Kisspeptin (ng/mL)	1.50 (0.55–3.72)	0.20 (0.07 – 0.37)	<0.0001	0.07 (0.03 – 0.11)	<0.0001
Serum HCG (mIU/mL)	IUP (n=18)	SAB (n=20)	p value	N/A
Serum HCG (mIU/mL)	117202 (83975 – 148784)	4739 (1858 – 8650)	<0.0001	N/A
