BACKGROUND. There have been a few studies conducted on couples' sexual
behavior during pregnancy and the year postpartum, but those studies
contain sampling bias resulting from recruiting volunteers for sex res
earch. The sample for the current research was recruited for a far les
s sensitive study, and includes data from both mothers and fathers. ME
THODS. A total of 570 pregnant women and 550 of their husbands or part
ners were recruited and were interviewed on four occasions: (1) at the
fifth month of pregnancy (T1); (2) at 1 month postpartum (T2); (3) at
4 months postpartum (T3); and (4) at 12 months postpartum (T4). RESUL
TS. Although approximately 90% of couples engaged in sexual intercours
e at T1, T3, and T4, only approximately 19% did at T2. On average, cou
ples resumed intercourse at 7 weeks postpartum. At T2 and T3, women wh
o were breastfeeding showed significantly less sexual activity and les
s sexual satisfaction than women who were not. There were few differen
ces between women who gave birth vaginally and those who were delivere
d by cesarean section, except that the latter resumed intercourse some
what earlier. CONCLUSIONS. Practitioners providing family-centered mat
ernity care need to counsel couples about typical patterns of sexualit
y during pregnancy and postpartum, and about usual patterns during bre
astfeeding. Accurate information can help couples feel more comfortabl
e during the transition periods before and after childbirth. A discuss
ion of expected changes in sexuality should be routinely introduced by
the physician during prenatal care.
