Recent studies in Bengaluru reveal that microplastics are present in 69% of ovarian follicular fluid and 68% of testicular tissue samples from IVF patients, raising alarms about their detrimental effects on human fertility, including hormonal changes and sperm damage.
- 01Microplastics found in 69% of ovarian follicular fluid and 68% of testicular tissue samples from IVF patients.
- 02Higher plastic burdens are linked to lower fertilization rates and hormonal disruptions.
- 03Microplastics can cause inflammation and oxidative stress in ovaries, affecting egg quality.
- 04Men's fertility is also impacted, with microplastics linked to sperm damage and reduced sperm concentration.
- 05Endocrine-disrupting chemicals from microplastics may alter male reproductive function.

Recent research conducted in Bengaluru has identified alarming levels of microplastics in human reproductive tissues, with findings showing microplastics present in 69% of ovarian follicular fluid samples and 68% of testicular tissue samples from IVF patients. A study published in 'Ecotoxicology and Environmental Safety' correlates higher plastic exposure with decreased fertilization rates, hormonal changes, and sperm damage. Dr. Rohit Raghunath Ranade, a senior consultant, emphasized that human exposure to microplastics occurs daily through contaminated water, processed foods, and seafood. Additionally, synthetic fibers from clothing and personal care products contribute to this exposure. Dr. Gayathri Karthik Nagesh noted that microplastics can trigger inflammation and oxidative stress in ovaries, potentially leading to accelerated ovarian aging and reduced egg quality. Furthermore, Dr. Shreeja Karan highlighted that microplastics can carry harmful endocrine-disrupting chemicals, negatively affecting male reproductive health. Specific polymers like polyvinyl chloride (PVC) and polyethylene terephthalate (PET) have been linked to testicular shrinkage and lower sperm concentrations, raising significant concerns about the broader implications of plastic pollution on human fertility.
