Document Summary

Assisted reproductive technologies provide innovative ways to conceive offspring. Arts are used to avoid conception of a child with a particular genetic condition, or to overcome infertility. Male infertility is due to a low sperm count or sperm that cannot swim or are abnormal in structure. Female infertility can be due to an irregular menstrual cycle or blocked uterine tubes. Fibroid tumors, endometriosis, or a misshapen uterus may prevent implantation of a fertilized ovum, and secretions in the vagina and cervix may inactivate or immobilize sperm. Oocytes may fail to release a sperm-attracting biochemical. Early pregnancy loss due to abnormal chromosome number may be mistaken for infertility; this is more common among older women. A variety of medical tests can pinpoint some causes of infertility. Intrauterine insemination places donor sperm in a women s reproductive tract. A genetic and gestational surrogate mother is intrauterinely inseminated, becomes pregnancy, and then gives the baby to the father and his partner.
