What Is The Difference Between In Vitro And In Vivo Fertilization ( In Vivo vs In Vitro )

difference between in vitro and in vivo fertilization

Difference between in vitro and in vivo fertilization : You may have come across the words like “in vivo” and “in vitro” while reading scientific theories. In this post, we will explain these two terms in detail with real-life instances, pros and cons of these two terms.

In Vivo: It refers to within living. It suggests the work is done inside tissue or living organisms.

In Vitro: It refers to within the glass. It is a procedure carried out in a container or glass. It happens outside a living organism. The methods in Vitro include analyzing human, animal cells in a laboratory. The outcome of this experiment must be taken into account judiciously.

how are in vivo fertilization and in vitro fertilization similar how are they different

There are several key differences between the manner in which the studies are held in Vivo and Vitro and how they can be understood. So lets check difference between in vitro and in vivo fertilization.

In Vivo or Internal Fertilization

In Vivo, medical experiments are conducted inside a living organism. Fertilization or embryo takes place inside the female body In Vivo. The embryo is formed inside the uterus when Woman’s egg is fertilized with sperm. In Vivo or internal fertilization is a natural process and doesn’t take more than one egg from the egg follicle to form an embryo. As the fertilized egg is held on the uterus in the female body, the chances of survival rate of the embryo are higher In Vivo.

It’s quite rare for women to conceive twins In Vivo or internal fertilization. Most women conceive single offspring except in rare cases where they conceive twins. There are fewer chances of babies with defects In Vivo than external fertilization. 

In Vitro or External Fertilization

In Vitro, cells are retrieved from either humans or animals and conduct experiments at a lab. While deriving cells from humans or non-human, no harm is caused to humans and animals. It offers numerous benefits. External Fertilization is a process where sperm is fertilized with an egg in an IVF laboratory. Here the eggs are retrieved from women’s egg follicles for this type of fertilization.  To mature the eggs, certain medications are given to women.

With help of ultrasound, egg development can be monitored. In addition to a collection of eggs, a certain amount of sperm is retrieved from mans’ semen. Sperm is placed into each egg in an IVF lab by an embryologist using highly sophisticated equipment. The time for egg fertilization or embryo would be around one to two weeks. Thereafter embryos are transferred to the Uterus.

As it is External Fertilization, the success rates of these embryos are less as compared to internal fertilization. There are chances of multiple risks in external fertilization, as a number of embryos is transferred. In Vivo testing is quite often preferred over In Vitro as it’s suitable for observing the complete effects of an experiment on a living subject. So you gt idea of Difference between in vitro and in vivo fertilization for sure.
