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

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

They will also have the opportunity to invite their partners to participate.

Participants are offered a premium membership at Kindara.com, a fertility app (available to new Kindara members only).

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