Why Does It Take That Long for Sperm to meet Egg After IUI?

Once the sperm meets the egg, it penetrates deeper into the egg and tries to change the surface of the egg, so that no other sperm could not enter into it. Most women start to expect being pregnant as soon as fertilization complete but it is a type of myth women believe. Science says that until implantation there is no chance of pregnancy.

When sperm meets the egg, it would be the initial procedure and women will never expertise any symptoms of pregnancy. When fertilization happens, everything is completed, even the genetic makeup of the baby is built. Once the egg is fertilized, it grows rapidly and starts dividing into numerous cells, and enters into the uterus within 3 to 4 days of post-fertilization.

If you have taken additional medications for fertility before the IUI to stimulate ovulation, you should be more careful and protected. You should be in a better environment with a low internal temperature for implantation. Few things like swimming, bathing should be avoided to get rid of few infections, You may feel a little crampy which is a sign of working procedure, and taking a rest for a short while after IUI makes a woman more comfortable.

To know the reliable and optimum results, a pregnancy test should be taken exactly after 2 weeks of IUI treatment. The test results would show negative before 14 days due to the development of low pregnancy hormone. It will be the right choice to take a blood test to make sure about the pregnancy after fertilization as it provides accurate information and sensitive too which also gives the information about the right level of HCG.

Conclusion:

If the result is negative, after the first IUI treatment, you may take a chance by undergoing a second IUI treatment before proceeding with other fertility treatments. Though IVF has a higher success rate than IUI, it is more invasive and doctors recommend trying IUI before undergoing IVF.

Procedures of IUI differs concerning specialist and hospitals but the chance of getting pregnant is same. In rare cases, infections may occur due to reactions but it is avoided as far as possible by using sterile instruments. But this does not affect the chance of being pregnant.
