Ans: IUI with partner’s sperm is a fertility treatment where sperm is collected from the male partner, processed in a lab to concentrate the most motile sperm, and then directly inserted into the woman’s uterus during ovulation.
IUI with partner’s sperm is typically recommended for couples who can’t have sex “on command” i.e. during the time of predicted ovulation.
It is also useful for couples where intercourse may be difficult due to physical or psychological reason. Sometimes there can be erectile dysfunction or retrograde ejaculation and sometimes when the male partner may be regularly away during ovulation period (commonly job related).
Sometimes mild male factor infertility can be treated by IUI as well, though, ovulation induction can be simpler and far cheaper than IUI.
