This has consequences for pregnancy should it happen later. More broadly, the importance of regular sexual activity also has implications for fertility planning, and for IVF and other forms of assisted reproduction, which generally do not take sexual practice or history into account.
Evidence from animal research and clinical studies has led researchers to conclude seminal fluid — the fluid sperm are bathed in following ejaculation — plays an important role in fertility. Seminal fluid contains small molecules that act as biological signals.
What’s the Point of Sex? It’s Communication at a Biological Level
The tolerant profile matters if fertilisation takes place. Immune cells recognise the same transplantation antigens on the developing baby, and so support the process through which the embryo implants into the wall of the uterus and forms a healthy placenta and fetus. So over time, repeated contact with the same male partner acts to stimulate and strengthen a tolerant immune response to his transplantation antigens. Some forms of infertility and disorders of pregnancy are caused by immune rejection, when the process of tolerance is not adequately established.

A condition known as preeclampsia provides useful insights into how exposure to seminal fluid influences the success of pregnancy. Preeclampsia is an inflammatory disorder of pregnancy that compromises growth of the fetus, and often causes prematurity in babies. It can be life-threatening for mothers if left untreated.
Preeclampsia is more common when there has been limited sexual contact with the father before pregnancy is conceived, and is associated with insufficient establishment of immune tolerance in the mother. The length of time a couple have had a sexual relationship seems more important than the frequency of intercourse.
Affected women were more than twice as likely to have had a short sexual relationship less than six months compared to the women who had healthy pregnancies.
Healthier pregnancy after months of sex
Low birth weight babies were also more common in this group. Setting up a profile of immune tolerance that supports healthy pregnancy seems to be specific to the conceiving partner.
Women who change partners return to a baseline state , and must rebuild immune tolerance with the new partner.
