Common Causes of Infertility in Men

Iatros / September 21, 2026

What causes infertility in men? Learn the common causes of male infertility, including low sperm count, poor motility, abnormal sperm, hormonal problems and lifestyle factors.
When a couple is struggling to conceive, attention often turns quickly to the woman. But fertility is a shared reproductive issue, and male factors can contribute to infertility on their own or alongside female factors.
So, what causes infertility in men?
Common causes include problems with sperm production, low sperm count, poor sperm movement, abnormal sperm shape, blockages in the reproductive tract, hormonal problems, certain medical conditions, medications, previous surgery, and lifestyle or environmental factors. Sometimes, however, no clear cause is found.
The good news is that identifying a possible male fertility problem is often the first step toward understanding what options may be available.

Iatros / September 21, 2026

How do you know if you’re ovulating? Learn 7 common signs of ovulation, how to track your fertile window, and when irregular ovulation may need medical attention.
Trying to conceive can make you suddenly very interested in things you probably never thought much about before — cervical mucus, cycle length, ovulation tests and even tiny changes in your body.
And one question comes up again and again: How do you know if you’re ovulating?
Some women notice clear physical signs around ovulation, while others don’t feel anything unusual at all. Common clues include changes in cervical mucus, a rise in basal body temperature, a positive ovulation predictor test, mild pelvic discomfort and changes in the menstrual cycle. However, no single symptom can confirm ovulation with certainty in every person.
Understanding these signs can help you identify your fertile window and better understand your menstrual cycle.
