Five of the Most Common Causes of Infertility

Infertility isn’t an uncommon issue as one in eight couples may experience it at during their lives. If you and your spouse have been trying to conceive for at least a year without any results, there may be some sort of fertility issue. Here are five of the most common fertility issues.


To become pregnant, a woman must ovulate so the eggs can enter the womb where they would be fertilised. However, if she is not ovulating regularly, or at all, an OBGYN should examine her. The most common cause of ovulation problems is PCOS or Polycystic Ovary Syndrome.

This condition causes cysts to form on the ovaries and prevents eggs from reaching the fallopian tubes and entering the womb. PCOS is often the result of weight gain or hormonal issues, which can be treated successfully.

Low Sperm Count

A man may have a low sperm count which causes infertility, but it can sometimes be treated. Low sperm counts can be the result of lifestyle habits like drinking too much alcohol, or being overweight. A fertility doctor may do a sperm count to eliminate other issues.

Even if the sperm count is low, the doctor can extract the fastest, most active sperm and inject them directly into the womb to attempt to fertilise an egg using IUI. If you’re having trouble conceiving, learn more about fertility test in Singapore to help diagnose the problem.

Blocked Fallopian Tubes

If a woman has one or both fallopian tubes blocked, her eggs cannot make their way to the womb to become fertilised. If only one fallopian tube is blocked, she could get pregnant every second month.

However, there are treatments which could unblock the tubes and restore regular ovulation so she could try to get pregnant naturally. In some cases, doctors will need to extract eggs from her and sperm from her spouse, fertilise them, and then implant them into her womb. This procedure, known as IVF, allows many couples to have healthy children.


Sometimes fibroids, which are benign tumours, will grow in the uterus and make it more difficult for a couple to conceive. Fibroids don’t cause infertility, they just hinder the process by blocking the womb, making contraception difficult.

If you find having sex is painful and you’re bleeding excessively during your monthly cycle, you should talk to an OBGYN to be tested. Fibroids can be minimised with prescription drugs, or they can be removed surgically.


Endometriosis is a common reason many women cannot conceive. Between 35% to 50% of all fertility problems in women are caused by this condition. Although the endometrium lining grows in preparation for conception, with this condition, it doesn’t get shed during menstruation and grows in places it shouldn’t. Some women with this condition can be successfully treated and conceive, but some are never able to have children.

If you’ve been trying to conceive for at least a year and have been unsuccessful, you need to consider getting tested to find out why.
