On World IVF Day 2026, fertility experts are drawing attention to an often overlooked cause of infertility: teratozoospermia. This condition, characterized by a high percentage of sperm with abnormal morphology, is increasingly diagnosed among couples who have been told their fertility reports are normal. According to a fertility expert speaking on the occasion, there has been a noticeable uptick in individuals presenting with teratozoospermia, a condition marked by a large number of sperms having an abnormal shape.
Understanding Teratozoospermia
Teratozoospermia is a form of male infertility where the sperm cells have structural defects that impair their ability to fertilize an egg. While standard semen analysis often focuses on sperm count and motility, morphology—the size and shape of sperm—is equally critical. An abnormal shape can prevent sperm from effectively penetrating the egg, leading to difficulties in conceiving naturally or even with assisted reproductive techniques.
Why Normal Tests Miss It
Many fertility clinics routinely check sperm count and movement but may not thoroughly assess morphology. Even when morphology is evaluated, criteria such as the World Health Organization's strict normal forms can sometimes miss subtle abnormalities. The expert noted that patients often arrive with routine reports showing normal parameters, yet they struggle to achieve pregnancy. In such cases, a detailed morphology analysis uncovers teratozoospermia as the underlying issue.
Implications for Fertility Treatment
For couples affected by teratozoospermia, advanced treatments like intracytoplasmic sperm injection (ICSI) during IVF can bypass the morphological barrier. However, the condition may also be linked to lifestyle factors, oxidative stress, or genetic issues. The increase in cases underscores the need for comprehensive fertility testing that includes in-depth sperm morphology assessment.
World IVF Day Awareness
World IVF Day serves as a platform to educate the public about such conditions. The fertility expert emphasized that if a couple's fertility reports are normal but pregnancy remains elusive, investigating sperm morphology could reveal teratozoospermia. This condition, while concerning, can often be addressed with appropriate medical intervention, turning the tide for many hopeful parents.
