Causes of Reduced Semen Volume
It is common for men to experience a decrease in both the volume and force of ejaculation as they age. A noticeable reduction in ejaculate volume is a prevalent concern among men. Several factors can contribute to diminished semen volume, including the following:
- Hormonal imbalances affecting testosterone production.
- Side effects from cancer treatments, such as radiation therapy for prostate cancer.
- Certain medications, including those for managing high blood pressure, depression, and benign prostatic hyperplasia.
- Diabetes.
- Health issues related to the testes.
- Experiencing retrograde ejaculation, where ejaculation occurs towards the bladder instead of the penis.
- Prostatectomy.
- Cystectomy.
Risk Factors for Reduced Semen Volume
Various factors can elevate the risk of reduced semen volume in men. Below are some of these risk factors:
- Obstruction: Scarring in the prostate, bladder, or urethra, or surgical interventions, may lead to decreased semen volume. Congenital blockages in the ducts responsible for semen ejaculation can also contribute to this issue.
- Frequent ejaculation: The volume of semen may diminish with frequent ejaculation, although semen volume can increase by approximately 12% each day during the first four days following the last ejaculation.
The Relationship Between Reduced Semen Volume and Testosterone
Testosterone is one of the key male hormones, playing a critical role in sperm production, as well as bone strength, muscle mass, and sexual desire. This hormone is vital for the proper functioning of the prostate and seminal vesicles, both of which are essential for semen production. Consequently, a decline in testosterone levels can lead to a decrease in semen volume, along with a range of other health issues, including fatigue, decreased energy, reduced muscle mass, and smaller testicle size.
