Does Tamsulosin Make You Last Longer in Bed?

There are several ways to delay ejaculation and last longer in bed. Sometimes, delay in ejaculation comes as a by-product in the form of side effects when you use a medicine. Tamsulosin or Flomax is one such prescription medicine that’s said to make men last longer in bed.

Does tamsulosin make you last longer in bed? Should you use it for premature ejaculation?

Let’s find out…

What is Tamsulosin?

Tamsulosin or tamsulosin HCI (also known as Flomax Relief and Flomaxtra XL) is a prescription medicine for enlarged prostate. It belongs to the class of drugs known as alpha-blockers. All alpha-blockers keep veins and arteries relaxed and open to ensure proper blood flow with lower blood pressure.

Tamsulosin relaxes muscles in the prostate gland and bladder to ensure smooth blood flow and proper urination. The prostate increases in size with age and as it grows in size, it pushes the urethra which decreases urine flow. The prostate gland is located right below the bladder so an increase in size creates issues in urination and the condition is known as benign prostatic hyperplasia (enlarged prostate).

Tamsulosin relaxes prostate and bladder muscles to ensure you can pee easily.

Side Effects

Here are the side effects that you may experience after using tamsulosin:

  • Dizziness
  • Lightheartedness
  • Ejaculation problems.

Does Tamsulosin Make You Last Longer in Bed?

Yes, it does.

A common side effect of tamsulosin is that it delays ejaculation and makes you last longer in bed. This side effect appears in 1% of men who take tamsulosin.

A 12-week clinical study reported that tamsulosin delays ejaculation and ejaculatory volume. It doesn’t just treat enlarged prostate, but it also helps cure premature ejaculation. Another study reported that taking tamsulosin 0.4 mg per day for 12 weeks improves sexual function significantly.

A review study reported that the absence of ejaculation is the most common side effect of alpha-blockers. Other sexual side effects found were erectile dysfunction and reduced libido.

Higher doses of tamsulosin are linked to abnormal ejaculation (0.8 mg) while lower doses are often considered safe, according to clinical studies as reported by FDA. Abnormal ejaculation includes a decrease in volume, ejaculation failure, and delay in ejaculation.

This is further verified by a study that reported no significant changes in sexual function and ejaculation when participants consumed 0.2 mg of tamsulosin per day.

Tamsulosin will make you last longer in bed if you are taking a high dose (0.4 or 0.8+ mg). Lower doses don’t lead to a delay in ejaculation.

Does Tamsulosin Affect Sperm?

Yes, tamsulosin may impact sperm quality. This is supported by multiple clinical studies.

A double-blind placebo-controlled randomized crossover study analyzed the impact of tamsulosin on sperm parameters. Participants took 0.8 mg of tamsulosin for 5 days. The sperm count in semen decreased, semen viscosity declined, sperm movement also declined, and the percentage of abnormal sperms increased marginally. The study reported that tamsulosin negatively impacts sperm in healthy men.

A study evaluated the impact of tamsulosin on semen quality and ejaculation in bucks. No ejaculation issues were found, however, authors reported changes in semen parameters. The negative impact on semen quality was dose dependent.

With imbalanced ejaculation and poor sperm quality, fertility issues in men who take tamsulosin are not uncommon. A decline in semen quality leads to fertility problems.

Tamsulosin impacts semen and sperm quality negatively. This impact is dose dependent with higher doses causing more damage. However, semen quality recovers in 6 to 12 months after discontinuing tamsulosin.
