施打hCG於COH末期，造成FSH & LH 下降
施打hCG於COH末期, 懷孕率高於傳統COH(37  vs  29%)
施打hCG於COH末期, rFHS 劑量低於傳統COH(1273 vs 1617iu)

Serum hormone levels on last day of stimulation before final oocyte maturation*

	rFSH standard treatment group** mean (SD)	Low-dose hCG treatment group** mean (SD)	Between-group difference (95% CI)	P-value for between-group difference***
FSH (IU/l)	14.6 (3.3)	8.2 (4.2)	−6.4 (−8.4 to −4.5)	<0.001
LH (IU/l)	2.5 (4.3)	1.4 (1.4)	−1.1 (−2.8 to 0.6)	0.20
E2 (pg/ml)	2044 (1204)	2250 (1739)	206 (−555 to 966)	0.59
Progesterone (ng/ml)	1.2 (0.4)	1.1 (0.8)	−0.1 (−0.4 to 0.2)	0.54
hCG (IU/l)	0.1 (0)	8.8 (10)	8.7 (5.2–12.2)	<0.001

• *All calculations have been carried out to full arithmetic precision, but results are shown as rounded values. Absolute between-group difference = (Low-dose hCG group value [third column]) − (rFSH group value [second column]). A negative value in the fourth column favours Low-dose hCG.
• **Mean values per patient (SD).
• ***P-values for t-test for independent samples; significant P-values <0.05 are bold
