In Vitro Fertilization
IVF stands for in vitro fertilization. It’s one of the more widely known types of assisted reproductive technology (ART). IVF works by using a combination of medicines and surgical procedures to help sperm fertilize an egg, and help the fertilized egg implant in your uterus. First, you take medication that makes several of your eggs mature and ready for fertilization. In vitro fertilization (IVF) is a type of assistive reproductive technology (ART). It involves retrieving eggs from a woman’s ovaries and fertilizing them with sperm. This fertilized egg is known.
Related to in vitro fertilization: artificial insemination. They are fertilized with sperm in a laboratory procedure, and then the fertilized egg embryo is returned to the woman's uterus. IVF is one of several assisted reproductive techniques ART used to help infertile couples to conceive a child. If after one year of having sexual intercourse without the use of birth control a woman is unable to get pregnant, infertility is suspected. Some of the reasons for infertility are damaged or blocked fallopian tubes, hormonal imbalance, or endometriosis in the woman.
In the man, low sperm count or poor quality sperm can cause infertility. IVF is one of several possible methods to increase the chance for an infertile couple to become pregnant. Its use depends on the reason for infertility. IVF may be an option if there is a blockage in the fallopian tube or endometriosis in the woman or low sperm count or poor quality sperm in the man.
There are other possible treatments for these conditions, such as surgery for blocked tubes or endometriosis, which may be tried before IVF.
IVF will not work for a woman who is not capable of ovulating or a man who is not able to produce at least a few healthy sperm. The screening how to set a double long spring trap and treatments for infertility can become a long, expensive, and sometimes, disappointing process. The anxiety of dealing with infertility can challenge both individuals and their relationship. The added stress and expense of multiple clinic visits, testing, treatments, and surgical procedures can become overwhelming.
Couples may want to receive counseling and support throughout the process. In vitro fertilization is a procedure where the joining of egg and sperm takes place outside of the woman's body.
A woman may be given fertility drugs before this procedure so that several eggs mature in the ovaries at the same time. Eggs ova are removed from a woman's ovaries using a long, thin needle. The physician gains access to the ovaries using one of two possible procedures. One procedure involves inserting the needle through the vagina transvaginally. The physician guides the needle to the location of the ovaries with the help of an ultrasound machine.
In the other procedure, called laparoscopya small thin tube with a viewing lens is inserted through an incision in the navel. This allows the physician to see inside the patient, and locate the ovaries, on a video what is the purpose of in vitro fertilization. Once the eggs are removed, they are mixed with sperm in a laboratory dish or test tube. This is where the term test tube baby comes from.
The eggs are monitored for several days. Once there is evidence that fertilization has occurred and the cells begin to divide, they are then returned to the woman's uterus. In the procedure to remove eggs, enough may be gathered to be frozen and saved either fertilized or unfertilized for additional IVF attempts.
IVF has been used successfully sincewhen the first child to be conceived by what is lpar in ibm aix method was born in England. Over the past 20 years, thousands of couples have used this method of ART or similar procedures to conceive.
Other types of assisted reproductive technologies might be used to achieve pregnancy. A procedure called intracytoplasmic sperm injection ICSI uses a manipulation technique that must be performed using a microscope to inject a single sperm into each egg. The fertilized eggs can then be returned to the uterus, as in IVF. In gamete intrafallopian tube transfer GIFT the eggs and sperm are mixed in a narrow tube and then deposited in the fallopian tube, where fertilization normally takes place.
As in IVF, the fertilization of the eggs occurs in a laboratory dish. Once a woman is determined to be a good candidate for in vitro fertilization, she will generally be given "fertility drugs" to stimulate ovulation and the development of multiple eggs. These drugs may include gonadotropin releasing hormone agonists GnRHaPergonal, Clomid, or human chorionic gonadotropin hcg.
The maturation of the eggs is then monitored with ultrasound tests and frequent blood tests. If enough eggs mature, the physician will perform the procedure to remove them.
The woman may be given a sedative prior to what is the purpose of in vitro fertilization procedure. A local anesthetic agent may also be used to reduce discomfort during the procedure.
After the IVF procedure is performed the woman can resume normal activities. A pregnancy test can be done approximately days later to determine if the procedure was successful. The risks associated with in vitro fertilization include the possibility of multiple pregnancy since several embryos may be implanted and ectopic pregnancy an embryo that implants in the fallopian tube or in the abdominal cavity outside the uterus.
There is a slight risk of ovarian rupture, bleeding, infections, and complications of anesthesia. If the procedure is successful and pregnancy is achieved, the pregnancy would carry the same risks as any pregnancy achieved without assisted technology. Success rates vary widely between clinics and between physicians performing the procedure and implantation does not guarantee pregnancy.
Therefore, the procedure may have to be repeated more than once to achieve pregnancy. An ectopic or multiple pregnancy may abort spontaneously or may require termination if the health of the mother is at risk. The number of multiple pregnancies has decreased in recent years as technical advances and professional guidelines have led to implanting of fewer embryos per attempt.

See also conception and reproduction. Called also fecundation and impregnation. After injection into the vagina, millions of sperm cells spermatozoa make use of their whiplike tails to swim through the cervix toward the uterus.
Most are destroyed along the way by secretions in the vagina, but some reach the uterus and a few may enter the fallopian tubes. A very small number may survive as long as 48 hours. If during this period only one sperm succeeds in entering a fallopian tube and meeting there an oocyte ready to be fertilized, conception can occur. This event is possible only during a period of about 4 days of the month. After the sperm lodges in the oocyte, the tail disappears, but the head unites with the oocyte to form the zygote.
When the largest follicle reaches 20 mm in diameter the patient is given an injection of human chorionic gonadotropin to induce expulsion of the oocyte from the follicle. A process in which usually multiple oocytes are placed in a medium to which sperm are added for fertilization.
The zygote thus produced is then introduced into the uterus and allowed to develop to term. Youngson Collins Dictionary of Biology, 3rd ed. Hale, V. Saunders, J.

Why the Procedure is Performed
Apr 02, · In vitro fertilization (IVF) is the joining of a woman's egg and a man's sperm in a laboratory dish. In vitro means outside the body. Fertilization means the sperm has attached to and entered the egg. Apr 25, · In Vitro Fertilization is an assisted reproductive technology (ART) commonly referred to as IVF. IVF is the process of fertilization by extracting eggs, retrieving a sperm sample, and then manually combining an egg and sperm in a laboratory dish. The embryo (s) is then transferred to the uterus. Other forms of ART include gamete intrafallopian transfer (GIFT) and zygote intrafallopian . In vitro fertilization is a procedure where the joining of egg and sperm takes place outside of the woman's body.

In vitro fertilization IVF is the joining of a woman's egg and a man's sperm in a laboratory dish. In vitro means outside the body. Fertilization means the sperm has attached to and entered the egg.
Normally, an egg and sperm are fertilized inside a woman's body. If the fertilized egg attaches to the lining of the womb and continues to grow, a baby is born about 9 months later. This process is called natural or unassisted conception. This means special medical techniques are used to help a woman become pregnant. It is most often tried when other, less expensive fertility techniques have failed. IVF is done to help a woman become pregnant. It is used to treat many causes of infertility , including:.
IVF involves large amounts of physical and emotional energy, time, and money. Many couples dealing with infertility suffer stress and depression. A woman taking fertility medicines may have bloating, abdominal pain , mood swings, headaches, and other side effects.
Repeated IVF injections can cause bruising. In rare cases, fertility drugs may cause ovarian hyperstimulation syndrome OHSS. This condition causes a buildup of fluid in the abdomen and chest.
Symptoms include abdominal pain, bloating, rapid weight gain 10 pounds or 4. Mild cases can be treated with bed rest. More severe cases require draining of the fluid with a needle and possibly hospitalization. Risks of egg retrieval include reactions to anesthesia, bleeding, infection, and damage to structures surrounding the ovaries, such as bowel and bladder. There is a risk of multiple pregnancies when more than one embryo is placed into the womb.
Carrying more than one baby at a time increases the risk for premature birth and low birth weight. However, even a single baby born after IVF is at higher risk for prematurity and low birth weight. IVF is very costly. Some, but not all, states have laws that say health insurance companies must offer some type of coverage. But, many insurance plans do not cover infertility treatment. Fees for a single IVF cycle include costs for medicines, surgery, anesthesia, ultrasounds, blood tests, processing the eggs and sperm, embryo storage, and embryo transfer.
After embryo transfer, the woman may be told to rest for the remainder of the day. Complete bed rest is not necessary, unless there is an increased risk for OHSS.
Most women return to normal activities the next day. Women who undergo IVF must take daily shots or pills of the hormone progesterone for 8 to 10 weeks after the embryo transfer. Progesterone is a hormone produced naturally by the ovaries that prepares the lining of the uterus womb so that an embryo can attach. Progesterone also helps an implanted embryo grow and become established in the uterus.
A woman may continue to take progesterone for 8 to 12 weeks after becoming pregnant. Too little progesterone during the early weeks of pregnancy may lead to miscarriage. About 12 to 14 days after the embryo transfer, the woman will return to the clinic so that a pregnancy test can be done.
Statistics vary from one clinic to another and must be looked at carefully. However, patient populations are different in each clinic, so reported pregnancy rates cannot be used as an accurate indication of one clinic being preferable to another. Outlook of live birth rates depend on certain factors such as mother age, prior live birth, and single embryo transfer during IVF. Catherino WH. Reproductive endocrinology and infertility.

In vitro fertilization IVF. There are five basic steps to IVF: Step 1: Stimulation, also called super ovulation Medicines, called fertility drugs, are given to the woman to boost egg production.
Normally, a woman produces one egg per month. Fertility drugs tell the ovaries to produce several eggs. During this step, the woman will have regular transvaginal ultrasounds to examine the ovaries and blood tests to check hormone levels.
Step 2: Egg retrieval A minor surgery, called follicular aspiration, is done to remove the eggs from the woman's body. The surgery is done in the doctor's office most of the time. The woman will be given medicines so she does not feel pain during the procedure. Using ultrasound images as a guide, the health care provider inserts a thin needle through the vagina into the ovary and sacs follicles containing the eggs.
The needle is connected to a suction device, which pulls the eggs and fluid out of each follicle, one at a time. The procedure is repeated for the other ovary. There may be some cramping after the procedure, but it will go away within a day. In rare cases, a pelvic laparoscopy may be needed to remove the eggs. If a woman does not or cannot produce any eggs, donated eggs may be used. Step 3: Insemination and Fertilization The man's sperm is placed together with the best quality eggs.
The mixing of the sperm and egg is called insemination. Eggs and sperm are then stored in an environmentally controlled chamber. The sperm most often enters fertilizes an egg a few hours after insemination. If the doctor thinks the chance of fertilization is low, the sperm may be directly injected into the egg.
This is called intracytoplasmic sperm injection ICSI. Many fertility programs routinely do ICSI on some of the eggs, even if things appear normal. Watch this video about: Intracytoplasmic sperm injection. Why the Procedure is Performed. It is used to treat many causes of infertility , including: Advanced age of the woman advanced maternal age Damaged or blocked Fallopian tubes can be caused by pelvic inflammatory disease or prior reproductive surgery Endometriosis Male factor infertility, including decreased sperm count and blockage Unexplained infertility.
Medical studies have shown so far that fertility drugs are not linked to ovarian cancer. It is unclear whether IVF increases the risk for birth defects.
