Table 5 Accuracy of LH and androstendione cut-off points to predict spontaneous ovulation and life birth

	Spontaneous ovulation (n = 100)			Life birth (n = 71)
	LH >12.1 IU/l	Androstenedione >3.26 mg/dl	LH >12.1 IU/l and androstenedione >3.26 mg/dl	LH >12.1 IU/l	Androstenedione >3.26	LH >12.1 IU/l and androstenedione >3.26 mg/dl
