Infertility - Fertilization Techniques
Tip! In fact, the symptom of not conceiving in 1 year alone is one good basis for diagnosing infertility.
In the procedure called In Vitro Fertilization (IVF), a woman’s egg is removed surgically from one of her ovaries and fertilized in a glass dish (”test tube”). This fertilized egg is later placed back in her uterus. This method was originally designed for women who have an obstruction of both fallopian tubes but have at least one normally functioning and surgically accessible ovary or in some other situations that cannot be corrected. These conditions exist in about five to ten percent of infertile women.
Tip! This occurs when both couples present conditions that may be identified as causes of infertility.
Overcoming infertility by a commercial transaction with a woman located through an advertisement or a lawyer remains controversial as a result of the notoriety of the “Baby M” case. The procedure, which consists of implanting an in vitro fertilized egg in the uterus of a woman who did not produce the egg (a variant of the original in vitro fertilization approach) has been forbidden in many states as well as in many countries worldwide. Unpaid surrogacy remains a viable option for the woman who can call on the cooperation of a close friend or family member to carry the embryo to term.
Technically called “cryopreservation”, the freezing of eggs, sperm and early stage embryos fertilized in the lab for future use in IVF cycles has become a routine procedure. For many years, frozen sperm banks have been the source for donor insemination and it is not unusual for men going off to war to leave a supply of frozen sperm to be used in the event of their death in combat. Male cancer patients under fifty who are scheduled to undergo radiation and chemotherapy likely to leave them sterile are advised to have their sperm preserved before beginning treatments.
Tip! Acupuncture works for infertility by increasing the production of endorphins or brain chemicals that help to reduce stress. It also improves blood supply to the ovaries, and the uterus.
It is anticipated that a woman undergoing chemotherapy, perhaps for breast cancer, will be able to have strips of her own ovary removed, frozen and put back in place when treatments are concluded, thus preserving her fertility for the future. The first In Vitro Fertilization birth using a frozen embryo occurred in the United States in 1986 and since then, doctors have been routinely freezing extra human embryos produced by IVF so that they can be stored until the couple asks for them again.
Until definitive decisions are made by the highest courts on who “owns” theses embryos in the event of a divorce, litigation abounds at the state level. At the same time, medical ethicists and legal specialists admit current laws were formulated at a time when no one anticipated that the essence of life could be frozen and used to create a new offspring even after the father was dead.
Tip! There is not much that the medical community hasn’t unraveled yet when it comes to infertility. This article will focus on the causes of infertility for both men and women.
Increasingly popular is the technological advance that eliminates any need for third-party collaboration. Known as GIFT (gametic intrafallopian transfer) and developed at the Health Science Center of the University of Texas, it proceeds in the following way. Egg cells (usually two to four) that are extracted from the woman by laparoscopy are mixed with about one thousand sperm from the spouse and again, by using a laparoscope, a catheter is introduced into the open end of one or both of the woman’s fallopian tubes and the sperm and eggs injected. Thus, the embryo can be fertilized inside the oviduct in its natural environment, where cell division takes place without the need for laboratory culturing. When the procedure works as anticipated, the embryo descends into the uterus and develops into a normal fetus. This procedure takes about one hour and can be performed on an outpatient basis.
Tip! The primary factor in secondary infertility is age.
