Cesarean section is rarely a cause of infertility. If the surgical procedure is followed by a severe pelvic infection, abnormalities can develop in the uterine lining; this is called intrauterine adhesion formation. Adhesions might also form around the fallopian tubes and ovaries.
But even for those women with postcesarean infection, the risk of sterility is low. It appears that zinc in the amniotic fluid that is released into the abdomen during the delivery may play a role in minimizing infections of the pelvic cavity and fallopian tubes. Other hormonal changes that occur with pregnancy may also minimize the risk of scar tissue formation. When compared with other similar pelvic surgeries, in fact, sterility is less a factor after cesarean than after most other open abdominal procedures.Web MD article
Jan. 14, 2004 -- Women who deliver their first child by C-section may have more trouble getting pregnant again, a new report from Scotland suggests.
When compared with moms who had difficult deliveries ending in vaginal birth, women in the study who had cesarean deliveries said they had more problems getting pregnant after the birth of their first child. Roughly 20% of the cesarean mothers reported difficulty conceiving a second child, compared with 5% of women who had vaginal deliveries aided by instruments like forceps.
But a childbirth expert who commented on the study for WebMD says fertility issues are way down the list of concerns regarding cesarean section.Conceiving Again After C-Section
For a number of reasons, many women don’t conceive another child after a C-section.3 Part of this decreased fertility is voluntary — a woman may not want to face childbirth again after experiencing a cesarean.4 Moreover, a cesarean operation is a convenient time to perform tubal sterilization. Some women take advantage of the timing rather than face a separate procedure later. Studies have shown, however, that not all of the lower fertility can be accounted for by sterilization.5 In Great Britain, researchers found that once she started to try and get pregnant after a cesarean, one in eight women took more than a year to conceive. After natural birth, the figure was one in twelve.
