Teratozoospermia (also called Teratospermia) refers to malformed shape of the sperms. Sperm morphology refers to the size and shape of the sperms and when the sperm morphology is defective, the condition is referred to as Teratozoospermia. When less than 4% of the sperms are in perfect shape, then the person is said to be suffering from Teratozoospermia condition.
ICSI – IntraCytoplasmic Sperm Injection – In order for fertilization to occur, sperm should penetrate the egg. Sometimes the sperm cannot penetrate the outer layer. A procedure called Intra Cytoplasmic Sperm Injection (ICSI) can help fertilize the egg by injecting the sperm directly into the egg.
Artificial insemination refers to the process of delivering the sperm into the cervix/uterus of a woman without having actual sex. There are mainly two ways of delivering the sperm and in one of the procedures, the sperm is ‘washed’ and delivered into the uterus to achieve better success rates.
Did you know that the number of infertility cases in men (and women) have been gradually increasing with time? Every year (from 1970), sperm count has been declining in men at the rate of 1.4% with an overall decline of 52.4% in the last 40 years.
PICSI- Physiological Intra Cytoplasmic Sperm Injection Fertility depends on the quality of the sperm and the egg. Qualitatively better gametes result in better fertility rates. This obviously happens in nature. A challenge in vitro however is to determine what constitutes the best quality gametes. When an ICSI procedure is planned, sperms are usually chosen based…
