Infertility is the diminished ability to conceive a child. Infertility can be a problem with both men and women. Infertility in men can be caused by medical conditions, unhealthy habits, and toxins from the environment. Infertility in women can be caused by problems with ovarian function, the Fallopian tubes, or the physical characteristics of the uterus. Methods of conceiving for couples that cannot conceive include intrauterine inseminations (IUIs) or in vitro fertilization (IVF), specific drugs, assisted reproductive technology (ART), surgery, and gestational carrier.
