We studied 500 women who conceived after investigation and treatment for different infertility problems and compared the outcome of the 5 infertility groups (Group 1 to 5), the ovulatory dysfunction (Group 1), male infertility (Group 2), A.I.D. (Group 3), tubal surgery and IVF (Group 4) and no treatment (Group 5) with the outcome in the hospital group during a period of 3 years. The incidence of abortion in Group 3 is significantly higher (13.8%), the incidence of ectopic pregnancy is significantly higher in Group 4 (21.7%) as compared with the incidence in the hospital group (P less than 0.01). The rate of pre-existing hypertension and gestational diabetes is significantly higher in all the 5 infertility groups as compared with the incidence in the hospital group (P less than 0.05). The incidence of preterm labor in general is less in the infertility group as compared with the incidence in the hospital group (P greater than 0.05). The incidence of older women, multiple pregnancy, induction of labor, operative deliveries, fetal distress, low Apgar score, babies with birth weight below the tenth centile were higher in the infertility groups (P less than 0.05). But the perinatal mortality or major or minor fetal anomalies were not significantly different in the infertility groups as compared with the rate in the hospital groups (P greater than 0.05).
