Can fertilization occur if the husband used Bravera Control And we didn't use a condom?

Yes. Unprotected sex is always associated with the risk of pregnancy. Bravera Control spray is not a fertilization preventative. Bravera Control is an over-the-counter spray medication indicated for use before sexual intercourse in men for premature ejaculation. The active ingredient is lidocaine. The preparation reduces the sensitivity of the penis to touch and thus delays ejaculation. To check if fertilization has occurred, a pregnancy test should be performed 10-14 days after intercourse.

Bravera Control can be purchased from an online pharmacy as a home delivery option:
