There are many steps to ensure that this process works including ovary stimulation, egg collection, fertilization, and embryo transfer. To stimulate the ovaries to produce more eggs than usual, the person must take specific hormones prescribed by a doctor. [40] Then, the eggs are collected using an ultrasound-guided aspiration needle.
The patient's fertilized eggs are placed on top of a layer of cells from the patient's own uterine lining, creating a more natural environment for embryo development. In zygote intrafallopian transfer (ZIFT), egg cells are removed from the woman's ovaries and fertilized in the laboratory; the resulting zygote is then placed into the fallopian tube.
Thus, when eggs are thawed and pregnancy is desired, a fertilization procedure known as intracytoplasmic sperm injection (ICSI) is performed by an embryologist whereby sperm is injected directly into the egg with a needle rather than allowing sperm to penetrate naturally by placing it around the egg in a dish.
Human fertilization is the union of an egg and sperm, occurring primarily in the ampulla of the fallopian tube. [1] The result of this union leads to the production of a fertilized egg called a zygote, initiating embryonic development. Scientists discovered the dynamics of human fertilization in the 19th century. [2]
Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete (haploid reproductive cells, such as a sperm or egg cell) with a single set of chromosomes combines with another gamete to produce a zygote that develops into an organism composed of cells with two sets of chromosomes .

These organs are responsible for the production of the egg cells (ova) and the secretion of hormones. The process by which the egg cell (ovum) is released is called ovulation. The speed of ovulation is periodic and impacts the length of a menstrual cycle. After ovulation, the egg cell travels through the fallopian tube toward the uterus.
