The first step in IVF is stimulating the ovaries. This is done by injecting a Follicle Stimulating Hormone (FSH) to increase the number of eggs the woman produces. Once the eggs have matured, they are removed from the ovaries by putting a needle into the fluid filled sacs, which hold the eggs, and aspirating them out. Figure 1 – Egg removal The semen is then collected and put into a test tube, with the sperm that have poor motility being filtered out. The eggs are then inseminated with the sperm and cultured in a laboratory for 16-20 hours.
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.

3 Approximately 50,000-100,000 motile spermatozoa are added to each egg and incubated overnight. However if fertilization does not occur, Intracytoplasmic Sperm Injection is performed, where eggs are directly inseminated Fertilised eggs are incubated for 2 more days before implantation. Typically, 2 to 4 embryos are implanted to increase pregnancy chances. A catheter is used to transport the embryos, with additional fluid, to the upper part of the uterus. 5 Therefore completing the IVF procedure.
Benefits of Breastfeeding While researching about the benefits of breastfeeding I found many advantages to it. The longer a mother breastfeeds her baby, there is a higher chance that her baby will get the healthy benefits of breastfeeding. There are many benefits to breastfeeding for the mother, child, and society. The benefits for a breastfeeding baby are: early breast milk is called liquid gold, it is easier to digest, it fights diseases, and it changes as your baby grows. Doctors tell breastfeeding mothers to breast feed their baby until it is up to 2 years of age.

It contains a complete set of the genetic information necessary for the development of a baby. Half of that genetic material comes from the mother, carried in the egg; the other half comes from the father, carried in the sperm cell. That means the baby will have a combination of characteristics from both parents. The next step after fertilization consists of the fertilized cell floating down the fallopian tube toward the uterus, where the cell divides into two. Those two cells then divide to make four, and the division continues.
