Baby Later, an affiliate of Houston Infertility Clinic, provides cryopreservation for sperm and egg cells, both of which may be used with in vitro fertilization (IVF) to create a new human life -- a baby -- later.

Up to now, the most common use of cell cryopreservation techniques has been by patients who are about to undergo life-saving cancer treatment. Both chemotherapy and radiation treatments can cause lifelong infertility due to the cellular damage caused by such therapies.

Chemotherapy for conditions besides cancer - such as lupus, for example - can also result in infertility.

Baby Later provides a way for these men and women to rescue their fertility by freezing their sperm and eggs before cancer treatment begins.
