In the ordinary process, the man's sperm enters into the woman's uterus upon completion of the sex act, and a sperm then fertilizes an egg within the uterus, if the woman happens to be in the right phase of her menstrual cycle. With in vitro fertilization, on the other hand, the fertilization process happens within laboratory equipment, outside of the woman, after both the woman and the man have contributed reproductive cells to the doctors. This is why an infant who is produced in this way is colloquially sometimes referred to as a "test-tube baby:" the moment of conception occurs not within the uterus of the mother but rather within the relevant laboratory tools. In vitro fertilization, while it can in fact successfully produce an embryo, has several risks that the woman should perhaps consider before following through with the process. This has to do both with the side effects of the fertility medications prescribed to the woman as well as the somewhat invasive nature of first retrieving eggs from the woman and then reinserting an embryo into the woman.
The technique of in vitro fertilization or IVF removes several eggs from the ovaries for fertilization in the laboratory. After a few days, one or two of these fertilized eggs which are now known as embryos are returned to the uterus in the hope that they implant and become a pregnancy. Women undergoing IVF are given special reproductive hormones to encourage several eggs to develop in the ovaries. Final maturation of the egg itself is induced by the administration of a further hormone. Thirty-six hours later, the fluid containing the eggs are drawn from the ovary with a needle; this is usually performed under light sedation in a short, outpatient procedure with the doctor using ultra-sound to check proceedings.
IVF stands for in vitro fertilization which mean ‘’in lab conception’’, or “out of the body conception”. This is the process in which matured eggs and sperm, either from a donor or the parents, are combined in a petri dish in the hopes of fertilization. This process enables couples who have fertility problems to have the chance to have children, but should it be used to choose the gender of your unborn baby? IVF can be expensive, time-consuming, invasive and mentally and emotionally tiring but it is a procedure that is often used by couples wishing to start a family but are infertile for one reason or another, whether the fallopian tubes are blocked, or when male infertility cannot be overcome by with Intrauterine insemination (IUI) treatment.
There, one of them may meet with the egg as it travels down one of the tubes toward the uterus. Intercourse is not the only way to get sperm in position. Another way is for a doctor to place sperm cells directly into the woman's uterus at the right time in her cycle, a technique called intrauterine insemination. These sperm can also swim up the fallopian tubes, seeking the egg. Furthermore, when the sperm meets the egg, they attempt to penetrate the egg's outer layer.
In Vitro Fertilization (IVF) is a procedure in which an egg (oocyte) from a woman’s ovaries is removed and separately fertilized with male sperm in a laboratory before being implanted into the woman’s fallopian tubes. 1 2 The first stage of IVF is called superovulation. Follicles are structures within which the oocyte develops, in order to retrieve multiple follicles several hormone and drug combinations are administered. Consequently, the ovary stops function and allows the follicles to ripen at the same time when stimulated therefore providing an increased number of eggs to harvest. Follicles are considered mature after 8 to 9 days and human chorionic gonadotropin (hCG) is administered which enables the final maturation of the oocytes.3 Oocyte retrieval occurs through a procedure called ultrasound guided vaginal retrieval.
When the doctor locates the eggs, he inserts a needle to get them out. Step number 3 is Insemination: after retrieval, doctors inspect the eggs and decide which egg is the most conceivable for a successful pregnancy. Then he places the eggs in a laboratory, while they retrieve the father’s sperm. The sperm is then added to the eggs in an incubator. An incubator is a device that preserves eggs and keeps them warm.
In the egg retrieval process females receive blood and ultrasound testing is completed every 1-3 days to check the development of the follicles in the ovaries. In this process the women has minor surgery. This surgery is called follicular aspiration. Follicular aspiration occurs to remove the eggs from the women’s body. The doctor inserts a small needle through the vagina.

This is where both the egg and the sperm come from donors. The egg and sperm are fertilised outside of the body using IVF and are then inserted into the womans womb mechanically. This method may be chosen if both partners are infertile, but the womans womb is capable of carrying a child full-term. The donation process of sperm is much the same as the donation of eggs. It is usually anonymous unless the couple chooses people personally.
In vitro fertilization or fertilisation is a process by which an egg is fertilised by sperm outside the body: in vitro . The process involves monitoring and stimulating a woman 's ovulatory process, removing an ovum or ova from the woman 's ovaries and letting sperm fertilise them in a liquid in a laboratory. The fertilised egg is cultured for 2–6 days in a growth medium and is then implanted in the same or another woman 's uterus, with the intention of establishing a successful pregnancy. IVF techniques can be used in different types of situations. It is a technique of assisted reproductive technology for treatment of infertility.
