Artificial Insemination (AI)

About Artificial Insemination(AI)

Artificial insemination is a simple and inexpensive medical procedure, commonly used in the treatment of infertility. AI is just one of those options that may be considered prior to attempting more involved treatments, such as IVF.It refers to the technique that involves placement of the sperm into the female reproductive tract by artificial means. In majority of the cases, the husband's sperm is used.
Advanced techniques like IVF; ICSI or donor insemination might have to be considered in some cases where the attempts are not fruitful.
The technique has also been used in animals for breeding purposes to improve productivity of milk and beef.
