Hi,
normal semen analysis value for motility should be 50% or more with progressive forward motility.
Reduced sperm motility is called asthenospermia, that is your problem.
IUI is a better option for the treatment of infertility due to asthenospermia.
The success rate with IUI is 20 to 40% depending on different institutes.
The success rate can be increased when along with IUI, superovulation is performed.
Means inducing the ovulation with hMG or hCG.
It may take 4 to 6 cycles to get success.
But don't worry sometimes with first attempt only success can be achieved. Your doctor will explain you the remaining things. All the best.
take care.

hello,

welcome to healthcaremagic.

The success rate of IUI depends upon several factors.
Men with normal sperm counts who are unable to have intercourse have a much higher chance of success than patients who are undergoing IUI for poor sperm counts or decreased sperm motility.

In addition, female factors play an important role.The hormonal level of the female, other associated medical conditions. If the female is more than 35, the chance of a successful pregnancy is significantly decreased.

Generally, the chance of conceiving in one cycle is about 10-15%; and the cumulative conception rate is about 50% over 4 treatment cycles. (Remember, Nature's efficiency for producing a baby in one month is about 15 to 25 %). However, if IUI is going to work for a couple, it usually does so within 4 treatment cycles. If a pregnancy has not resulted by this time, the chances of IUI working for you are very remote.

After IUI one should explore the option of IVF .
