This method’s invention was a great boon for couples that couldn’t have a child due to specific health issues. For instance, if the male partner’s sperm isn’t motile or doesn’t have the required speed, it will not be able to reach the egg and fertilise it. This method can help that couple.
If the woman has a high pH level in her cervix, that could also kill all the sperms, this method can help such couples too.
In simple words, this method can greatly help couples who cannot have a child due to low sperm speed or any other obstacle preventing the sperm from meeting the egg.
This process is a little different from natural conception. Here, natural intercourse for egg fertilisation is bypassed, and during your ovulation window, the most potent sperm are planted directly into your fallopian tube for maximum chances of fertilisation.
