Causes of Low Sperm Count and Watery Sperm

| 29 May 2023 | 1697 Views |


Life is full of mysteries. And of all the mysteries, those connected with human reproduction are some of the most intriguing. As a team devoted to providing solutions to fertility-related issues, India IVF Fertility is committed to shedding light on these mysteries. Today, we’re unpacking two concerns many men are reluctant to discuss, yet are anxious to understand: the causes of low sperm count and watery sperm.

Delving into the Complexities of Male Fertility

When it comes to fertility, most people think it’s all about the female factor. But here’s a fact that might knock your socks off: male infertility accounts for 40-50% of all infertility cases. That’s right, gentlemen, you’re just as much in this game as the ladies. Now let’s dive into the heart of the matter.

Causes of Low Sperm Count

A low sperm count, also known as oligospermia, can be the culprit behind a couple’s struggle to conceive. There are several factors that could contribute to this situation:

  1. Hormonal Imbalance: Hormones produced by the pituitary gland are crucial for sperm production. If these are out of whack, you could be looking at a lower-than-normal sperm count.
  2. Varicocele: This is a swelling of the veins that drain the testicle. It’s the most common reversible cause of male infertility.
  3. Infections: Certain infections can interfere with sperm production or cause scarring that blocks the passage of sperm.
  4. Environmental Factors: Exposure to heavy metal, radiation, or chemicals can affect sperm production. Overheating the testicles, possibly through frequent use of saunas or hot tubs, could also be a factor.
  5. Certain Medications: Long-term use of anabolic steroids, certain antibiotics, and other medications can impact sperm production. If you’re concerned about this, do discuss it with your healthcare provider.
  6. Drug and Alcohol Use: Substance abuse can decrease sperm numbers. Heavy drinking can lower testosterone levels and cause decreased sperm production.
  7. Obesity: Research suggests that increased body mass index (BMI) is linked with decreasing sperm count and sperm motility.
  8. Chromosomal or Genetic Causes: A variety of genetic or chromosomal disorders can result in low sperm count. Examples include Klinefelter’s syndrome and cystic fibrosis.
  9. Undescended Testicles: This condition, which is most common in male infants, occurs when one or both of the testicles fail to descend from the abdomen into the scrotum before birth.
  10. Emotional Stress: Severe or prolonged emotional stress, including stress about fertility itself, might interfere with hormones needed to produce sperm.

What’s Behind Watery Sperm?

Men often express concern about watery semen. While it’s usually nothing to panic about, here are a few causes:

  • Frequency of Sexual Activity: Frequent ejaculation can lead to watery semen.
  • Simply put, if you’re firing off rounds faster than your body can fully restock, you could end up with a less viscous substance.
  • Low Semen Concentration: This means your semen contains fewer sperm cells per milliliter. Lower concentration could make your semen more fluid.
  • Retrograde Ejaculation: In this condition, semen enters the bladder instead of emerging through the penis during orgasm. While it doesn’t pose a health threat, it can lead to infertility and more watery semen.


When it comes to fertility, knowledge is power. Understanding the causes of low sperm count and watery sperm is a step towards demystifying male fertility. Remember, it’s not a journey you need to embark on alone. Reach out to the experienced team at India IVF Fertility, and let’s explore this mysterious terrain together.

Yes, often through lifestyle changes. Regular exercise, a healthy diet, adequate sleep, and avoiding substances like tobacco and excessive alcohol can all help.

Age can have a significant impact. Sperm count tends to decrease naturally as men age, starting around the age of 40.

Not necessarily. While a higher sperm count can enhance fertility, the viscosity of semen doesn't directly correlate with fertility potential.

While it's the most common reversible cause of male infertility, not all men with varicocele experience fertility issues.

Yes, treatments range from surgery to correct an underlying issue, hormone treatments, and medications, to assisted reproductive techniques like IVF.
