Obstetric outcome of 424 pregnancies after intracytoplasmic sperm injection

An evaluation of the outcome of pregnancies resulting from intracytoplasmicsperm injection for severe male factor infertility was conductedby analysing the data obtained from the patients and/or theirobstetrician/gynaecologist on standardized questionnaires. Thedata from 424 pregnancies between April 1991 and September 1994were analysed. Early pregnancy loss before 16 weeks occurredin 99 cases (23.3%), including 48 clinical abortions (11.3%),47subclinical pregnancies (11.1%) and four ectopic pregnancies(0.9%). Vanishing twins and triplets, which could be regardedas early embryonic wastage, were found in 36 cases (8.5%). Onepregnancy was interrupted at week 15 of gestation because ofanhydramnios, and four pregnancies (0.9%) ended in spontaneouslate abortions before 26 weeks. A total of 320 pregnancies (75.5%)resulted in the birth of at least one child; 222 of these (69.3%)were singletons, 93 were twins (29.1%) and five were triplets(1.6%). The problems of prematurity and low birthweight wereespecially related to the multiplicity of pregnancies. Furthermore,from among the total of 423 babies born, we have observed threecases of stillbirth and five cases of neonatal mortality. Theperinatal mortality rate was therefore 18.9 per 1000 births.The results of this study show that the obstetric outcome ofthese pregnancies was similar to that obtained after conventionalin-vitro fertilization and other assisted reproduction techniques.
