Cialis is an FDA-approved oral prescription medication.
It treats Erectile Dysfunction (ED) or Benign Prostatic Hyperplasia (BPH) in men.
ED is the difficulty in getting and maintaining an erection, and BPH is a condition that causes problems with urination.
The worldwide use of Cialis for treating ED in men has raised a question: Does Cialis cause infertility in men?
Infertility in males is the inability to start a pregnancy with your partner. Even with frequent unprotected sexual activity, they may not be able to conceive for at least a year.
This is a serious problem for many couples.
Let us explore more about Cialis and if it can cause infertility.
Basics of Cialis
Cialis is an oral Erectile Dysfunction pill available in different strengths like 2.5 mg, 10 mg, 20 mg, 60 mg, etc.
Cialis is taken once daily or before sexual activity, depending on your situation and what condition it is treating.
Cialis contains Tadalafil as its active ingredient. Therefore, it falls under the category of Phosphodiesterase 5 (PDE5) inhibitors.
Cialis typically starts working within a time frame of 30 min. to 2 hrs after you take it.
It is famously known as the “weekend pill” because Cialis lasts for as long as 36 hours after consumption.
Cialis helps address Erectile Dysfunction by relaxing the blood vessels that lead to the penile region.
This increases blood flow toward the penile area and helps in achieving and maintaining an erection.

Research suggests that the on-demand use of a PDE5 inhibitor is safe and does not affect sperm mortality.
Thus, infertility is not a known side effect of Tadalafil (Cialis).
Another research states that Tadalafil administration improves the quality of sperm cells and seminal fluid.
More research done on mice shows the same results.
Therefore, it’s safe to say that there is no link between Cialis and infertility.
Always consult a doctor to discuss medication and the appropriate Cialis dosage.
