It is an artificial insemination process where the sperms are placed in the uterus while eggs are released for fertilisation to occur. IUI is the technique of inserting a processed semen sample containing motile sperms into the uterus cavity around the time of ovulation through the cervix into the uterine cavity. When medication and timed intercourse fail, IUI is usually the first line of treatment. Patients with a modest to moderate decrease in sperm count and motility, as well as minor endometriosis, should consider it. Ovulation induction may be coupled with IUI for women who do not ovulate on a regular basis. Pavithram specialty clinic is the best IUI centre in Chennai. IUI may also be recommended for some couples who are experiencing infertility for no obvious reason.
