A new study found no difference in sexual enjoyment between women who gave birth via caesarean section and those who delivered vaginally. However, women who had a caesarean section were more likely to report sex-related pain at later stages postpartum.
A water birth significantly reduces the use of epidurals, injected opioids, episiotomy, pain, and heavy bleeding after birth, while increasing mothers' satisfaction levels and the odds of an intact perineum. A water immersion also increases the likelihood of an intact perineum and reduces episodes of umbilical cord breakage.
A new study by researchers at the University of Copenhagen found that an imbalance in vaginal bacteria is associated with a higher risk of emergency caesarean section. The study analyzed 1,396 samples from 736 pregnant women and discovered that those with greater levels of imbalance were more likely to deliver via C-section.

The research found that pelvic organ prolapse progresses slowly, with women who gave birth vaginally being about five years ahead in progression compared to those who delivered by Caesarean section.
Scientists discovered that women are more susceptible to Zika infection due to a suppressed vaginal immune response. The delayed antiviral immune response allows the virus to remain undetected in the vagina, increasing the risk of fetal exposure during pregnancy.
Researchers at the University of Florida identified cells targeted by a male hormone and found that excess hormone exposure during fetal development can cause vaginal defects in females. The study found a specific window of hormonal influence and a type of cell responsible for guiding the developing vagina to its correct position.
