In vitro fertilization, better known as IVF is an assisted reproductive technology in which fertilization takes place in the lab instead of inside the body. The literal meaning of the phrase in vitro is "within the glass.
This is the opposite of in vivo , which means within the body or literally, "within the living". Today, IVF is a mainstream— albeit expensive —fertility treatment. An estimated 8 million IVF-conceived babies have been born around the world.
The road to successful IVF treatment was long and trying. Thanks to the bravery and persistence of the early scientists and doctors, the technology of in vitro fertilization are available today. Here's a very short explanation of what happens during IVF:. The woman takes fertility drugs , which stimulate the development of extra oocytes or eggs in the ovaries. This takes place over a number of days. Then, the mature eggs are removed from the ovaries either from the intended mother or from an egg donor.
This is done with an ultrasound-guided needle. In the lab, the retrieved eggs are combined with sperm from either the intended father or from a sperm donor.
The egg and sperm are put together in a petri dish, where hopefully a sperm cell will fertilize an egg cell. A fertilized human egg cell is called an embryo. The resulting embryo then develops for a few more days in the lab. This is done under very carefully controlled conditions. Any extra embryos are frozen for future cycles.
Hopefully, pregnancy will result. IVF success rates are good, but pregnancy is never a guarantee. Despite the name, "test tube babies" are not developed in a test tube. Test tubes are not part of the modern IVF process at all. With IVF, the egg is fertilized in a petri dish. Not a test tube. When the embryo is between three and five days old, it is transferred to the uterus. To be clear, the embryo does not develop into a fetus in the lab. That idea belongs to the realms of science fiction.
The term test tube baby was first used in the s. Then, it was used to refer to artificial insemination —not IVF. It is an in vivo fertilization — in the body — and not in vitro , in the lab, like IVF. Hermann Rohleder. The book, entitled Test Tube Babies: A History of the Artificial Impregnation of Human Beings , is described as, "including a detailed account of its technique, together with personal experiences clinical cases, a review of the literature, and medical and legal aspects involved.
IVF had not yet been invented. When the first human egg was fertilized outside of the body in , the term test tube baby began to refer to IVF babies.
More on her below. Most in the fertility world consider the term "test tube baby" offensive and inappropriate because of the negative, sci-fi imagery it conjures up. In , Dr. Gregory Pincus successfully fertilized rabbit eggs in the lab.
He did not use male rabbits in the process. Through a process known as parthenogenesis, he was able to take eggs from female rabbits, force fertilization of the eggs through chemical means, and then transfer the fertilized eggs back into the female reproductive tract of a rabbit.
His work caused great controversy and concern. The experiments and negative publicity led him to lose his tenure at Harvard University. But not everyone saw Dr. Some saw hope and promise. Rock hired Dr. Miriam Menkin and Dr. Pincus then spent the next six years attempting in vitro fertilization of human ova. During their research, they collected human ova and tried to fertilize Finally, in the spring of , Pincus and Menkin decided to lengthen the amount of time the egg and sperm were together in the petri dish.
They were finally able to successfully fertilize four eggs. But this did not stop progress. Landrum Shettles attempted to replicate Dr. He was successful. Shettles was also able to keep the fertilized egg alive and developing until day six. Day six is when an embryo would typically implant itself into the uterine lining. He went on to publish Ovum Humanum , a book containing over 1, pictures of the human egg at various stages of development.
In the meantime, in England, Dr. Robert Edwards was attempting in vitro fertilization with mice eggs. He was successful and wanted to do the same with human eggs. He tried for years but had no luck. Howard Jones was a reproductive surgeon , treating infertility surgically. His wife, Dr. Georgeanna Jones, was a reproductive endocrinologist. She treated infertility with non-surgical methods. After returning to England, Dr. Edward met Dr.
Patrick Steptoe. Steptoe had invented a then-new surgical procedure known as laparoscopy. This is a surgical technique where a small incision is made in the abdomen, and a camera and tools are put through that incision.
This would be far less invasive than the other surgical options at the time. Jones told Dr. Rarely, the drugs can cause ovarian hyperstimulation syndrome OHSS. This happens when the ovaries over-respond to the gonadotrophins, so that too many eggs develop in the ovaries. Severe abdominal swelling and shortness of breath can result. If OHSS occurs, the doctor may suggest restarting the whole cycle with a lower dose of gonadotropin. The leading cause of pregnancy loss, whether in IVF or in natural conception, is an abnormal number of chromosomes, known as chromosomal aneuploidy.
Detecting aneuploidy in the egg or sperm before carrying out IVF, or in an embryo before implantation, may help increase the chance of a successful pregnancy. In , scientists announced that they had developed a new technology called time-lapse imaging. The technique may increase the chances of selecting a suitable embryo for successful IVF, though further research needs to be done. When more than one embryo is transferred into the womb, there is a higher chance of having twins, triplets, or more babies.
The doctor may recommend that there should only be a single embryo transfer in women with a heightened chance of having twins. Women who regularly lift heavy objects at work and work non-daytime shift patterns may experience decreased fertility, suggests new research.
