Sperm penetrating force analysis and Ovum Spindle Identification Technology help women who have repeated failed IVF treatment

Health News

There was a 33-year-old Mrs. Li who wanted to have her own child after her marriage, but was unable to do so after two times of failed IVF in the medical center, she turned to Lee Women’s Hospital reproductive medicine center for help; It turned out that she has the spindle deviation, fortunately, with the spindle body positioning technology performed by our team, she successfully conceived with only one attempt of embryo implantation and gave birth to a healthy and lovely twin daughter in June.


  • Her husband's sperm penetration force is lower than normal, as a result, the eggs can be fertilized normally through a single sperm microinjection

The director of Lee Women’s Hospital, Lee Mao Sheng, said that for this case, the hospital used the sperm penetration analysis leading in Asia and found that the sperm penetrability of the husband was lower than normal, and the sperm could not penetrate the eggs to achieve normal fertilization. Microinjection allows the egg to be fertilized normally. At the same time, it was found that the wife ’s spindle has deviation and it has abundant chromosomes and genes, if the chromosome on the spindle is damaged during sperm microinjection, it will affect subsequent embryo development and cause implantation failure, which is one of the reason why Mrs. Lee undergone two failed IVF treatments.

  • Ovum spindle identification technology can avoid damage to eggs during microinjection of sperm

Dean Lee Mao Sheng further explained that if the sperm are not mature enough or has functional defects, it may not be able to bind properly with the egg. Therefore, the hyaluronan binding assay (HBA) can be used clinically to predict the fertilization ability of sperm to eggs. And through the non-invasive ovum spindle identification technology, the spindle position can be accurately observed, which can effectively avoid the damage to the eggs during the sperm microinjection process. This technology is suitable for women who are at the advanced maternal age, premature ovarian failure, and repeated failure of IVF treatment. It is extremely helpful.

  • Ovum spindle identification technology enables more than 80% fertilization and doubles pregnancy rate

According to clinical statistics, the application of ovum spindle identification technology to women at advanced maternal age or women with premature ovarian failure can increase the fertilization rate to more than 85%, significantly improve the quality of embryos, and double the pregnancy rate. However, the above technologies are still not common in Asia, it also attracts many domestic and foreign patients who have failed IVF many times to come to Lee Women’s Hospital to conduct infertility examination as a result.

  • Advanced Reproductive Medicine Technology: Overcoming Infertility and Increasing Pregnancy Rate

It's hard to get pregnant, but it's all worth seeing after your baby is born. Mrs. Li expressed emotionally, thank you very much for giving me one last chance, and also thank Dean Lee Mao Sheng for helping the family fulfill their dream! With the continuous advancement of medical technology, we believe that more infertile couples will be able to overcome infertility and increase the pregnancy rate through advanced reproductive medical technology in the future!
