The inability to bear children has caused great pain to many married couples which wish to raise a family. The suffering of these couples must not be underestimated. Fortunately, modern medicine has devised a number of assisted reproductive technologies(ART) in order to help the plight of the infertile. Are these reproductive technologies acceptable for a Christian? What are the moral and ethical issues involved? It is these questions that I now consider.
But, I must first of all provide a glimpse into the technologies which are now available. There is a veritable alphabet soup of options. In ART, sexual intercourse is bypassed either by insemination or fertilization of the oocytes (eggs) in the laboratory (In vitro fertilization, IVF).
Artificial Insemination (AI) is when sperm is placed into the woman’s uterus or cervix using artificial means. An expansion of AI involves a sperm donor when the woman’s partner does not have functional sperm. Gamete intrafallopian transfer (GIFT) involves a mixture of eggs and sperm placed directly into a woman’s fallopian tubes using laparoscopy. This is usually preceded by a transvaginal ovum retrieval (OCR) in which a small needle is inserted into through the back of the vagina and guided by ultrasound into the ovarian follicles to collect eggs.
IVF is the technique of bringing about fertilization of the male and female gametes (sperm and eggs) outside the body. Fertility medications are often administered to the woman prior to IVF to stimulate the development of follicles in the ovary. IVF often involves one or more of the following techniques. OCR was explained in the previous paragraph. Intracytoplasmic Sperm Injection (ICSI), which is helpful when the male sperm counts are low, involves the injection of a single sperm into the center of an egg using a microneedle. Zygote intrafallopian transfer (ZIFT) involves the removal of eggs from the woman’s ovary, fertilization in the laboratory, and the placement of the resulting zygote into the fallopian tube.
Egg donors donate eggs when the mother is unable to produce or provide eggs due to a number of conditions. In this case, the eggs are removed from the donor, fertilized in the laboratory, with the embryos returned to the recipient’s uterus. Gestational carriers (or surrogates) are used when a woman’s medical condition prevents a safe pregnancy, if the woman has uterus, or if she is unable to carry a pregnancy to full term. Cryopreservation involves the freezing of eggs, sperm, or embryos for future use. Frozen embryos may be inserted in the body by the technique Frozen Embryo Transfer (EFT).
Next, some of the ethical implications of such technology.
