PRESTO (Pregnancy Study Online)

PRESTO is a web-based research study that examines whether lifestyle factors such as diet, exercise, and medication use have an impact on fertility and pregnancy.

Women are being invited to complete one online questionnaire at enrollment and every 2 months for 12 months, or until conception, whichever occurs first.

Women will also have the opportunity to invite their male partners to participate.

Half of enrolled women get a VIP membership at, an app that records menstrual patterns and fertility signs (available to new FF members only).

PRESTO is a non-profit study being conducted at Boston University. It is funded by the National Institutes of Health.
