That’s why boosting testosterone through supplements might actually decrease your sperm count. If you're curious about what lowers sperm count, testosterone supplements are a major factor. This may have affected TT measurements, as males with later blood draws may be falsely identified as having low TT due to the diurnal secretion of testosterone production in men. Along this line, studies have not shown a consistent pattern of abnormal semen parameters in men whose testosterone is low, but adequate for spermatogenesis to occur (5). An enlarged prostate can sometimes lead to urinary issues, which might indirectly affect sexual health. Some men might find that their erections become stronger and more frequent as their testosterone levels rise. If you have any concerns about changes in your sexual health while on TRT, don’t hesitate to consult with your healthcare provider. While some men may experience an increase in volume, others may notice no change or even a slight decrease. After that, sperm move into the epididymis, where they finish maturing and get stored until ejaculation. You can feel fine, have normal orgasms, and still learn your semen has little to no sperm. Once your diet is in check, avoid lifestyle habits that lower sperm volume, like smoking and not getting 8 hours of sleep every night. You should always contact your doctor or other qualified healthcare professional before starting, changing, or stopping any kind of health treatment. Wear loose clothing, as well, as pressure can decrease your sperm count. This is because testosterone directly impacts the tissues and nerves involved in the erectile process. Low testosterone is one of the hormonal issues that can contribute to ED. It can occur due to several factors, including psychological issues, physical health problems, or hormonal imbalances. It’s vital for DNA production, which is important for both sperm and eggs. If you’ve got low testosterone but still want to boost fertility, there are natural methods to consider. In fact, zinc and magnesium are often recommended to support male fertility . Zinc plays a key role in sperm development and maintaining a healthy hormone balance. Taking extra testosterone makes your body think it doesn’t need to produce any more naturally.
