[Myoma and infertility: analysis of the literature]

Abstract

The influence of myomas on reproduction has been clearly demonstrated, however their effects on fertility remain debated. The aim of this review, between January 1988 and December 2000, was to clarify the relation between myoma and fertility, and to assess pregnancy rates after myomectomy in infertile patients. Spontaneously, 54 publications were selected and 40 eligible. No study compared pregnancy rates with or without myomas. Pregnancy rates after myomectomy varied between 9.6% and 76.9%, with descriptive series. In medically assisted procreation, five publications were eligible. Myoma presence was associated with decreased pregnancy rates. Hysteroscopic sub-mucous myoma resection increased pregnancy rates. Relation between myoma and sterility is probable, however no proof was obtained. Myomectomy efficacy has not been statistically proven, but spontaneously almost 60% of patients became pregnant 24 months after surgery. Decreased pregnancy rates are observed when other infertility factors are associated. Concerning myomectomy in medically assisted procreation, conflicting results are available. Prospective randomised studies are needed.
