Dr. Nasha Reddy OBGYN Testimonials

After having our 4th baby, my husband and I decided our family was complete. Essure was the least invasive form of birth control, and made the most sense to my husband and I. The procedure was done in the office and was virtually painless other than mild cramping for a few hours following.
