Infertility is on the rise, and studies by the WHO report that it’s being observed in at least 1 out of 6 couples. Studies also report that approximately 27.5 million couples face infertility in India. In women, the causes of infertility can be seen due to Polyendocrine Metabolic Ovarian Syndrome(earlier PCOS), endometriosis, endometrial dysfunction, blocked fallopian tubes, hormonal imbalances, age-related decline in fertility, or even ovulation disorders. Infertility in men can be due to low sperm count, poor sperm motility, abnormal sperm function, hormonal issues, and infections.
For those couples undergoing IVF treatment, one of the biggest concerns is the safety and handling of their eggs, sperm, and embryos. They are often concerned about these factors and doubts regarding sample identification, and the possibility of embryo mix-ups can induce stress and anxiety during this journey, which is already overwhelming. According to Dr. Lalit Kumar, Head of Embryology and Scientific Director at Nova IVF Fertility and Motherhood Fertility & IVF, modern IVF labs are now redefining patient and gamete safety in India.
Over the years, the IVF procedure has evolved, with improvements in laboratory techniques, embryo culture systems, genetic screening, and patient care contributing to improved outcomes. Many couples worry if their eggs, sperm, and embryos will be handled safely throughout the process. Modern IVF laboratories are now dealing with these concerns by harnessing advanced technologies, strict quality controls, and highly standardised protocols to ensure accuracy at every stage of the procedure. With digital tracking of embryos, AI, and rigorous quality assurance, IVF labs help ensure safety, transparency, and confidence throughout treatment.
How have safety and IVF practices evolved over the years?
Currently, the Electronic Witnessing System (EWS) is widely used by modern labs. This technology verifies patient identity at every stage when it comes to the handling of eggs, sperm, embryos, and laboratory procedures. Unlike traditional manual double-checking that was done earlier, now electronic witnessing consists of various parameters, such as barcode, RFID, or digital tracking systems, to ensure that every sample is matched to the correct couple and there is no confusion at all. So, be assured and at ease, as every movement of gametes and embryos within the laboratory is now digitally recorded, creating a complete audit trail that can be evaluated whenever required. If a mismatch from the protocol is detected, the system will alert the embryology team immediately, thus preventing the chances of human error.
Even patient identification is verified by considering multiple checkpoints, right from sample collection and fertilization to embryo culture, embryo transfer and even embryo cryo preservation. Artificial Intelligence (AI) is now widely used by embryologists for additional support in selecting the best embryos. AI has become a “third eye” that can identify patterns that cannot be seen during routine observation. It can eliminate human bias and subjectivity involved when determining embryo quality. AI supports decision-making but will not replace the expertise of skilled embryologists. AI- assisted systems can be used to check sperm morphology, motility, and DNA Fragmentation Index (DFI), and will help with consistency in embryo assessment with a high degree of precision.
Currently, Single Embryo Transfer (SET) is the growing preference in fertility care. SET is becoming the recommended approach because it reduces the risks linked to multiple pregnancies. AI is expected to further strengthen this approach by helping embryologists select the precise embryo. Also, IVF laboratories operate under conditions that are often more demanding than those found in operating theatres. Embryology labs require strict control of temperature, humidity, air pressure, air particle size, and volatile organic compounds (VOC). Using advanced air filtration systems, which involve HEPA and charcoal filters, can be beneficial in maintaining a favourable environment for embryo development.
Daily quality assurance and quality control checks are done by experts without fail before any procedures start. Even minor factors such as perfumes and deodorants are not at all allowed within the laboratory environment as they may impact embryo development. So, an IVF lab begins its day with Quality Assurance and Quality Control without compromising.
Conclusion
Successful IVF outcomes are based on ethics, robust quality systems, and highly skilled embryologists who are cautious during every step of the procedure. Regular training, competency assessments, controlled laboratory access, digital traceability, and advanced electronic record management systems are allowing for patient safety. So, the couples can be confident during every step of their journey, which is backed by science and a strong commitment to transparency and safety.
