Ovuation may resume as early as 2 weeks after an abortion Lahteenma ki and Luukkainen (1978) deected surges of luteinizing hoemone (LH) 16 to 22 day in 15 of 18 woman studied. Moreover, plasma progesterone levels, which hadplummeted after the abortion, increased soon after the LH surges. These hoemonal events agree with histological changes observed in endometrial biopsies. Therefore, if pregnancy is to be prevented, effective conteaception should be initiated soon after abortion. If contraception is not desired, Grossman and colleagues (224) concluded that a visit to assess for complications is not necessary for procedures done before 50 days’ gestation.
