Definition - What does Primipaternity mean?

The word primipaternity literally means “first-time father,” and it refers to a person’s first pregnancy with a male partner. The primipaternity model is a theory which suggests that multiparous women who have a child with new partners are at an increased risk of developing preeclampsia.

Preeclampsia is associated with high rates of both maternal and fetal disease rates, and it can also result in the loss of the pregnancy as well as the death of the mother/surrogate.

FertilitySmarts explains Primipaternity

Preeclampsia has been called “a disease of first pregnancies,” as it is commonly seen in first-time mothers. It is a complication which is characterized by high blood pressure occurring 20 weeks after conception and having protein in the urine which can cause damage to the kidneys.

It is believed that having multiple children protects against preeclampsia, markedly lowering its incidence. The protective effect was lost when these women changed partners, which led to the primipaternity theory. It was initially thought that preeclampsia is a problem of primigravidity, but the idea exists that primipaternity may play a more significant role.

This theory has been challenged with the idea that the time interval between deliveries, known as the birth interval effect, played a more significant role.

There is no consensus on the impact of primipaternity and preeclampsia.
