During in vitro fertilization, eggs are removed from mature follicles within an ovary A. An egg is fertilized by injecting a single sperm into the egg or mixing the egg with sperm in a petri dish B. The fertilized egg embryo is transferred into the uterus C. In vitro fertilization IVF is a complex series of procedures used to help with fertility or prevent genetic problems and assist with the conception of a child. During IVF , mature eggs are collected retrieved from ovaries and fertilized by sperm in a lab.

The term smooth muscle refers to a muscle of the human body that is part of an involuntary muscle group. These muscles are extremely important to help the body perform a variety of crucial tasks, and can be found in many parts of the body. Keep reading to learn more about smooth muscle examples and how they function in the body. There are three types of muscles in the body: smooth muscles, cardiac muscles and skeletal muscles. Smooth muscles are unique in their largely involuntary response, and in their structure. Smooth muscles have a much stronger ability to contract than skeletal muscles, and are able to maintain contraction longer. Unlike skeletal muscles, which are located near bones and control bodily movement, smooth muscles are found in and around organs.

This technique is used in order to prepare the gametes for the obtention of embryos that may be transferred to a maternal uterus. With this method, the acrosome reaction is skipped. However, the steps to be followed before and after insemination are the same. This is because the acrosome reaction has to take place and thousands of sperm cells have to be involved in IVF.
The sperm is introduced into the uterus of a mammal or the oviduct of an oviparous egg-laying animal. In mammals, insemination normally occurs during sexual intercourse or copulation , but insemination can take place in other ways, such as by artificial insemination. In humans, the act and form of insemination has legal, moral and interpersonal implications. However, whether insemination takes place naturally or by artificial means, the pregnancy and the progress of it will be the same. Insemination may be called in vivo fertilisation from in vivo meaning "within the living" because an egg is fertilized inside the body, this is in contrast with in vitro fertilisation IVF.
