The Impact of Lifestyle and Environment on Sperm Quality, leading to Male Infertility
Fertility is not just a woman's problem. Male factors are involved in almost 50% of the infertility cases worldwide. However, several men remain unaware of their sperm health until they are trying to conceive.
According to several studies over the past four decades, global sperm counts have declined by more than 53%. This is a wake-up call for most men.
Today’s fast-paced world, lifestyle choices, environmental toxins, and even everyday habits like skipping sleep or a poor diet are silently affecting sperm quality. Understanding and improving your sperm health isn’t just about fatherhood. It’s about your hormonal balance, energy, mental clarity, and your future.
If you are in Bangalore, you don't have to go through the journey alone. At NU Hospitals, we understand the sensitivity of the condition. Therefore, keeping “YOU” in mind, we offer advanced diagnostics and personalized treatment to help you take control of your reproductive health.
Factors influencing sperm Quality

Your sperm health is linked to three main factors:
-
Sperm Count
Sperm count is the number of sperm present in a semen sample. A healthy count ranges from 15 million sperm to more than 200 million sperm per milliliter (mL) of semen.
Global sperm counts have dropped by over 53% in 40 years, raising fertility concerns.
-
Sperm Motility
Motility measures how well your sperm swims. At least 40% of your sperm should be actively moving for good fertility. Poor motility affects 1 in 4 men facing fertility problems.
-
Sperm Morphology
Morphology is the shape of your sperm. Having 4% or more normal-shaped sperm is healthy. Abnormally shaped sperm may reduce your sperm’s fertilizing ability.
Having healthy sperm quality increases the chances of conception.
