 Here's Why More Sex Increases a Woman's Chance of Getting Pregnant

Regular intercourse even during the 'non-fertile' period increases your chances of having a baby, revealed a new study. The study findings suggested that sexual activity triggers physiological changes in the body that increase a woman's possibility of getting pregnant. These results could eventually influence recommendations regarding how often to engage in sexual intercourse for couples trying for a baby.

Lead author Tierney Lorenz from Kinsey Institute at Indiana University in the US said, "It is a common recommendation that partners trying to have a baby should engage in regular intercourse to increase the woman's chances of getting pregnant, even during so-called 'non-fertile' periods, although it is unclear how this works."

Lorenz further added, "This research is the first to show that the sexual activity may cause the body to promote types of immunity that support conception. It is a new answer to an old riddle- How does sex that does not happen during the fertile window still improve fertility?"

The research team collected data across the menstrual cycle in 30 healthy women, about half of whom were sexually active and half of whom were sexually abstinent. The study findings were reported in two papers recently published in Fertility and Sterility and the Physiology and Behavior.

In the first paper, the researchers reported that sexually active women experienced greater changes in helper T cells, and the proteins that T cells use to communicate. In the second paper, the team reported differences in antibody levels between the two groups.

Lorenz said, "We are actually seeing the immune system responding to a social behavior- sexual activity. The sexually active women's immune systems were preparing in advance to the mere possibility of pregnancy."
