The effect of early administration of rectal progesterone in IVF/ICSI twin pregnancies on the preterm birth rate: a randomized trial

Table 2 Comparison of gestational age at delivery between both groups

		Progesterone group N = 102	Placebo group N = 97
Early fetal loss (n)		2 (2%)	4 (4.1%)	0.372
Gestational age at delivery (weeks)		34.7 ± 3.6	34.5 ± 4.5	0.626
Term births (n)	> 37 weeks	25 (24.5%)	27 (27.8%)	0.594
Preterm births (n)	< 37 weeks	75 (73.5%)	66 (68%)	0.551
	< 34 weeks	21 (20.6%)	21 (21.6%)	0.649
	< 32 weeks	9 (8.8%)	12 (12.4%)	0.46
	< 30 weeks	5 (4.9%)	7 (7.2%)	0.516
	< 28 weeks	5 (4.9%)	3 (3.1%)	0.555

Data is expressed either as a mean ± SD or n (%)
Preterm births are all spontaneous births, except for two patients in the progesterone group who had iatrogenic termination < 37 weeks because of severe pre-eclampsia with no neonatal morbidity or mortality
