Peri-implantation intercourse does not lower fecundability.

ABSTRACT:

Study question

Does sexual intercourse in the implantation time window (5-9 days after ovulation) reduce fecundability?

Summary answer

After adjustment for intercourse in the fecund window and clustering by couple, there was no association between intercourse in the implantation time window and fecundity.

What is known already

Previous research has suggested an association between intercourse in the peri-implantation time window (5-9 days after estimated ovulation) and reduced fecundability.

Study design, size, duration

We used data from the FERTILI study, a prospective observational study conducted in five European countries, with data collected from 1992 to 1996.

Participants/materials, setting, methods

Women who were experienced in fertility awareness
