World AIDS Day | Treatment technology of "cleanse" in IVF therapy

The theme of the 2020 "World AIDS Day" publicity activity is "Joining hands in epidemic prevention and fighting AIDS and sharing health responsibility" (English theme is "Global Solidarity, Shard Responsibility"). It aims to emphasize the strengthening of solidarity and cooperation in the global fight against the new crown pneumonia epidemic, strengthening and compacting the "four-party responsibility" of governments, departments, society and individuals, and jointly responding to the new crown pneumonia, AIDS and other major global infectious disease challenges, and jointly fighting AIDS. To achieve the goal of AIDS prevention and control and build a human health community. As global access to effective treatment has improved, people living with HIV are living longer than ever before. It is estimated that by 2030, 70% of people living with HIV will be 50 years old.


Therefore, the issue of fertility is also a concern of HIV-infected groups, how to have a healthy childbirth, what technology to use, and what preparations are needed. As many as 15% of Lishe Medical's ten-year cases are infected groups, and it has accumulated considerable experience in the operation of such cases.


Director Zheng is the chief embryologist of TMC, a master of science in embryology at Oxford University, and a senior embryologist certified by ESHRE (European Society of Human Reproduction and Embryology); Director Zheng obtained a master of science in clinical embryology from Oxford University in the UK. She is one of the first senior embryologists in Asia to be certified as senior embryologist by the European Society of Human Reproduction and Embryology (ESHRE). Director Zheng has more than 13 years of clinical embryologist experience and has been the chief embryologist of TMC fertility for 8 years. She has participated in more than 10,000 ART cycles, of which approximately 3,000 are PGD/PGS cycles. She is an indispensable part of the implementation of the quality system and has been certified by the TMC Fertility and Reproductive Technology Certification Committee (RTAC).


On November 15th, the 2020 international joint test tube baby theme seminar initiated by UT Lishe Co., Ltd. ended successfully. Among them, we invited Director Zheng, the chief embryologist of the Malaysian Liyang Fertility Center, also known as the TMC Fertility Center, to speak The "Semen Treatment Technology for Test Tube Therapy" mentioned the technique of "washing semen".


"Sperm washing" is our popular term for the semen processing technology that optimizes sperm. When HIV carriers are males, sperm washing techniques are needed. The principle is to inject semen into a test tube and mix it with an osmotic agent. After the mixture is rotated at a high speed in a centrifuge, it can separate sperm and eggs from other substances such as white blood cells, semen, etc., and virus carriers such as AIDS, hepatitis B, hepatitis C, and syphilis The virus exists in seminal plasma or blood, but sperm and eggs are healthy. Sperm lavage can remove as many unnecessary or even harmful sperm components as possible, including seminal plasma, dead sperm, inflammatory cells, anti-sperm antibodies and bacteria. Use healthy sperm to combine with eggs to form fertilized eggs, and then use PGD/PGS screening technology to detect blastocysts cultivated from fertilized eggs. Under the protection of double screening, it is ensured that healthy embryos are transplanted into the uterus.


During the Q&A session of the presentation, we selected some of the questions with the highest comments on the site and answered them online, such as: What kind of infectious diseases can be cleansed? Can it be cleaned? Does the process of washing sperm affect the quality of sperm? Will my baby still be at risk of infection after washing? Can washing sperm reduce the deformity rate of sperm? Open the video and watch it carefully!

As the (old age, high difficulty, high risk) fertility management expert, Lishe Medical; (infection blocking and reproductive safety) has always been the direction of Lishe Medical’s long-term efforts; with the accumulation of data over the years and the release of annual data, Lishe Medical The cognition of infection and fertility intervention has also deepened with the in-depth follow-up. Because the infected population (including all STD infections) accounts for more than 15% of the total population served by Lishe; whether there is a difference between the assisted reproductive process of the infected population and the normal population is the focus of controversy; because there is no support of big data, this part of the research is also A piece overlooked by many reproductive centers and management agencies. On the day of World AIDS Day last year, we published an article called World AIDS Day | A meta-analysis of 30 cases of HIV-infected patients with complicated fertility cases. Through the third-party assistance of 30 typical HIV infections managed by Lishe A meta-analysis of pregnancy medical records. In the same year, based on summarizing years of practical experience and in-depth research on the status quo of HIV infection and fertility needs, a comprehensive and practical guide for diagnosis, treatment and fertility-"Guidelines for Safe Childbearing and Assisting HIV" was compiled, which has been well received since its publication. The high praise from the majority of customers has made the HIV community no longer confused to a certain extent, and has continuously realized the transparency of fertility medical information.
