Analysis of the whole process of three-generation IVF technology: a reproductive revolution in the era of precision medicine

Three-generation IVF (PGT, pre-implantation genetic testing) technology has increased the pregnancy success rate to 72% (natural pregnancy rate is about 30%) and the blockage rate of genetic diseases to 99.9%. This article systematically reveals the scientific logic of this life project from four dimensions: technical principle, process innovation, quality control standards and prognosis management. I. Core principles of PGT technology and screening of indications PGT-A (aneuploidy screening): NGS technology detects 23 pairs of chromosomes and reduces the miscarriage rate (from 40% to 15%).PGT-M (single gene disease detection): SNP chain analysis + mutation locus verification, can diagnose cystic fibrosis, thalassemia and other 7000 + single gene diseasesPGT-SR (structural abnormality screening): whole genome microarray to identify balanced translocations (resolution up to 5Mb)…

Guidelines for Scientific Decision-Making in Labor and Delivery: Analysis of Biomechanical and Clinical Variables Affecting Conduct of Labor and Delivery

　　The decision on the mode of delivery is one of the most complex and dynamic assessment processes in obstetrics. In this article, we systematically analyze the scientific mechanisms affecting the success rate of vaginal delivery from three dimensions: biomechanics, clinical variables and uncontrollable factors, and establish a risk prediction model. 　　I. Biomechanical optimization path of vaginal delivery　　1. Golden ratio between fetal weight and maternal pelvis　　Ideal fetal weight should be controlled in the range of 2800-3300 grams (corresponding to a biparietal diameter of 8.5-9.5 cm). The risk of cephalopelvic disproportion (CPD) rises by 12% for every 100 gram increase in weight. For pregnant women of different body types:　　Dwarf body type (height 150cm³ increases the success rate of vaginal delivery to 85%.　　3….

International consensus on perioperative management of testicular microtesticular sperm extraction (micro-TESE)

　　I. Background and clinical significance　　Non-obstructive azoospermia (NOA) is the most serious type of male infertility. Microtesticular sperm extraction (micro-TESE) has been widely used worldwide as the primary means of obtaining sperm in patients with NOA. Its perioperative management covers key aspects such as patient education, endocrine evaluation, microsurgical operation, enhanced recovery after surgery (ERAS), testicular sperm freezing and thawing technique, and long-term follow-up. Standardized perioperative management is essential to improve sperm retrieval rate (SRR) and assisted reproductive technology (ART) outcomes. 　　History of technology development　　Origin: First proposed by Schlegel’s team in 1999, the technique identifies and extracts spermatozoa from focal seminiferous tubules by microscopic manipulation.　　Recommended by international guidelines:　　American Society for Reproductive Medicine (ASRM): micro-TESE is the procedure with the highest SRR…

Ways to Keep Your Ovaries and Eggs Youthful

　　　　Just as the body ages with age, so do the ovaries and eggs. So you should take care to maintain a regular routine in your daily life to keep your ovaries rejuvenated.　　When do women start to have eggs?　　Women are born with primordial follicles (cells that produce eggs) that are part of the ovaries, and most of these follicles die before they mature. A woman is born with about 2 million primordial follicles, but by the time she has her first menstrual period, only 200,000 to 300,000 follicles are left. Since then, the number of primordial follicles decreases by a few hundred each month, and by the age of 45, there are only a few thousand left. Only about 500 eggs…

Pregnancy rate increased by 12% after transplant, no injections or pills read this one enough!

　　If you have had a transplant, I am sure whether this wait is 14 days or 7 days or 10 days, this is going to be very torturous and long and are you scratching your head wondering when you should test.　　The truth is that whether you test or don’t test doesn’t stop you from ruminating all the time, leading to fluctuations in your mindset and negative emotions affecting the blood supply to the uterus, leading to disturbed uterine contractions and thus affecting the embryo’s ability to settle in the womb.　　A lot of anxiety comes from the unknown, today the circle sister to transfer the third day of fresh embryo as an example, the embryo in the uterus every day ‘work’…

Is third generation IVF the last straw for recurrent miscarriages? This fatal flaw cannot be ignored!

　　　　Third-generation IVF is commonly referred to as embryos that have passed chromosome screening, and if there are no problems in the maternal environment, the chances of success after the transfer are higher than the success rate of pregnancy with embryos that have not been screened.　　But is this really the case? We found an authoritative evidence and share it with you!　　01Three-generation IVF you may not fully understand　　We all know that three-generation IVF is subject to chromosome screening, which is actually different, and for different groups of people, the screening is completely different.　　Triple IVF can be divided into three categories depending on what is being screened:　　The first type of screening is called PGT-A: this way can check whether the chromosomes of the…

Egg mitochondrial supplements, in the end, which are IQ tax, which efficient and practical

　　　　Mitochondrial supplements, which we have covered in countless science articles, because mitochondria are so important to the egg, the circle has seen an investigation.　　To clarify the relationship between mitochondria and embryonic development, researchers collected human unfertilised oocytes, early embryos and embryos with arrested development.　　It was found that 67% of unfertilised oocytes had fewer mitochondria in the cytoplasm, and 60% of developmentally aborted embryos had a reduced number of mitochondria located near the nucleus.　　In oocytes, mitochondrial populations are maternally inherited and critical for developmental competence.　　Dysfunction of mitochondrial quality control mechanisms may lead to reproductive failure, and because of their central role in oocyte and embryo development, mitochondria have been described as a potential diagnostic and therapeutic target for assisted reproduction.　　The latest…

What to choose between fresh, frozen and blastocyst embryos? The right one for you is the best!

Blastocyst culture is another choice that many IVF families face after egg retrieval. There are various myths about blastocysts circulating among many IVF people, who believe that blastocysts are the best embryos, and that they should be taken to blastocyst culture as long as there are embryos available. 　　Firstly, let’s understand about cleavage stage embryos, blastocysts and frozen embryos　　Typically, when undergoing IVF to assist conception, we use ovulation stimulating drugs to promote the growth of a group of follicles, and when the eggs mature, they are removed through egg retrieval and combined with sperm in a petri dish to form an embryo. The embryo continues to develop outside of the body and is classified as a cleavage stage embryo or…
