Objective. The aim of this study was to determine the role of parental fact
ors that may relate to the pathogenesis of molar pregnancy.
Methods. A retrospective review of six patients who had a molar pregnancy w
ith at least two different partners at New England Trophoblastic Disease Ce
nter between 1965 and March 1999 was performed.
Results. A total of 34 pregnancies with 20 different partners were observed
in 6 patients. These pregnancies resulted in 15 (44.1%) hydatidiform moles
, 8 (23.5%) term live births, 7 (20.6%) therapeutic abortions, 3 (8.8%) spo
ntaneous abortions, and 1 pre-term delivery, While 5 patients had a molar p
regnancy with 2 different partners, 1 patient had a molar pregnancy with 3
different partners. Two patients developed persistent postmolar gestational
trophoblastic tumor in 3 (20.0%) of the 15 episodes of molar pregnancy. Th
ree of the male partners reported a total of 7 healthy children from prior
relationships.
Conclusion. The experience in these six patients suggests that a primary oo
cyte problem may contribute to the development of molar pregnancy. (C) 1999
