IntraUterine Insemination involves preparing a semen sample in a simple way, so that higher concentrations of the most motile sperms are selected and injected through the cervix around the time of ovulation in order to achieve high rates of pregnancy.
IUI is a simple OPD procedure , not a surgery . There is no need of any sedation or anaesthesia or painful injections . It is less expensive and less invasive than IVF/ICSI .
IVF is the process by which eggs are removed from ovaries and mixed with sperms in a laboratory culture dish. Fertilisation takes place in this dish, "in vitro" means "in glass". Successful IVF procedure is combined with a procedure known as embryo transfer, which involves physically placing the embryo in the uterus. ( IVF-ET)
The first successful birth of a "test tube baby", Louise Brown, occurred in 1978. Thousands of IVF babies have been born since the first in 1978.
In the history of fertility medicine, one of the most significant breakthroughs was the development of a process called intracytoplasmic sperm injection, or ICSI for short in 1990s. This technique was developed by G. Palermo at Brussel .
If there is male factor infertility and the couple is going through in vitro fertilization (IVF), then ICSI is a better procedure. It has revolutionized the treatment of male infertility as it allows couples to achieve fertilization even when only a few sperm are available.
ICSI may be for you if the male partner has:
Severe male factor ( Retrograde ejaculation/Electroejaculation)
Had a vasectomy
Low or no motility
Previous failed IVF cycles
IVF cycles with very low yield of eggs at the egg retrieval
Sperms aspirated from testis ( TESA )
Many patients choose to undergo the ICSI procedure to maximize their success even when there is no clearly defined indication .
