Intracytoplasmic Sperm Injection (ICSI)
Intra-cytoplasmic sperm injection (ICSI) involves injecting a single sperm directly into an egg in order to fertilise it. It is a process sometimes used during in vitro fertilisation treatment (see IVF patient information leaflet).The fertilised egg (embryo) is then transferred to the woman’s womb.
Why Choose an Intracytoplasmic Sperm Injection Procedure ?
An intracytoplasmic sperm injection (ICSI) is ideal in male factor infertility . It is recommended in multiple scenarios like :
- The sperm counts are low (oligospermia).
- Sperms are immotile (asthenospermia).
- Teratozoospermia(abnormal forms), necrozoospermia(dead forms), antisperm antibodies.
- The male partner does not ejaculate any sperm but sperm have been collected from the testicles/epididymis.
- Previous failed IVF.
How does ICSI work? :
ICSI is often recommended if:
- The male partner has a very low sperm count.
- Other problems with the sperm have been identified, such as poor morphology (abnormally shaped) and/or poor motility (poor swimmers).
- Other situations where the sperm count is zero and donor insemination is not wanted.
- The male partner has had problems obtaining an erection and ejaculating. This includes men with spinal cord injuries, diabetes and other disorders.
- At previous attempts at in vitro fertilisation (IVF) there was either failure of fertilisation or an unexpectedly low fertilisation rate.
- The male partner has had a vasectomy and sperm have been collected from the testicles or epididymis (sperm reservoir).
- The male partner does not ejaculate any sperm but sperm have been collected from the testicles.
