Reasons for being unable to conceive

Roughly 30% of the couples we see are unable to conceive due to an issue with the man’s fertility, and the cause lies with the woman in 30% of couples, too. There are multiple factors that can influence fertility in both men and women.

Causes for being unable to conceive - women

Menstrual cycle irregularities

A normal menstrual cycle does not take less than 21 or more than 35 days. During a regular menstrual cycle, ovulation will generally occur. If your cycle is irregular or your period failed to happen, though, ovulation may not take place. This can have a negative influence on your odds of conceiving. Hormonal imbalance can cause disruptions or irregularities in your menstrual cycle.

If you’re trying to conceive, it’s important to have a regular menstrual cycle. If ovulation doesn’t happen regularly, you’ll usually experience fewer ovulations a year, which decreases your odds of conceiving. In addition to this, irregular menstrual cycles make it more difficult to determine when ovulation (and, consequently, your fertile period) will take place. This, too may make it harder to conceive.

Decreased sperm quality

Sperm cell quality can be determined through a sperm quality examination. During one of these examinations, we check whether enough sperm cells are present in the sperm, whether the cells are agile enough and whether they have the right shape.

Sperm quality can fluctuate heavily. For this reason, we will always do a second examination if the results of the first one deviate heavily from the standard results. Sperm cells need roughly 72 days to develop, so if there were less than stellar circumstances during the three months prior to your examination, that may be an explanation for reduced sperm quality.
