IVF

Frozen sperm taken by biopsy from testicles in men with no sperm in their semen is as effective as fresh sperm taken by biopsy in helping couples conceive through in vitro fertilization (IVF), according to a School of Medicine study. Pictured is a section of human testicular tissue and sperm cells viewed through a microscope.

Obese women who use donor eggs to become pregnant through in vitro fertilization are just as likely to become pregnant as normal weight women, according to a new report. Pictured is the study’s first author, Emily Jungheim, MD, left, observing as Mary Bade uses assisted reproductive technology to inject a single sperm into an egg.
