Am I infertile?

Infertility is when a couple fails to conceive, in spite of participating in regular unprotected sex. Roughly 14% of couples, which is 3.5 million people in the UK face this problem. There are two types of infertility: primary infertility involves someone who has never experienced pregnancy in the past and has difficulty conceiving; secondary infertility involves someone who has had one or more pregnancies in the past but has difficulty conceiving again.

There are a range of different causes for infertility and why you may be struggling to get pregnant. However, for a quarter of couples a cause cannot be established. Our doctors run you through the most common the most common causes of infertility.

Common causes of infertility in both men and women:


 is another factor which can negatively affect ovulation in females. Furthermore, being severely underweight can prevent ovulation altogether.

Male fertility can also be reduced due to being overweight.


Sexually transmitted infections (STIs)

Some STIs can lead to infertility, including chlamydia, which can affect both male and female fertility. If you're struggling to fall pregnant, it might be worth checking your sexual health as part of your infertility investigations.



Increased stress can lead to a reduced sex drive (libido), which can then affect your chances of conception as you have less regular sexual intercourse. Very high levels of stress can also affect ovulation in females or sperm production in males. 

Healthy lifestyle, fertility

Obesity and stress can contribute towards infertility - leading a healthy lifestyle will increase your chances of conceiving naturally

Common causes of Infertility in women:


Ovulation disorders

Ovulation is the release of an egg from your ovaries each month, and is a part of the normal menstrual cycle. Disturbances in ovulation is the most common cause of infertility. Some disorders can prevent the egg from releasing at all; whereas others can cause irregular release- so that ovulation is randomly skipped in some cycles. Some conditions involving ovulation malfunction include: 

  • Polycystic Ovary Syndrome (PCOS): Polycystic ovaries contain many immature follicles, which are unable to produce or release eggs. Symptoms of this condition include an irregular menstrual cycle, excessive hair growth and weight gain.
  • Thyroid malfunctions: Ovulation is inhibited by both an overactive or underactive thyroid gland. We at LDC offer thorough thyroid function tests, which can be included in infertility investigations.


Fertility decreases as your age increases, with the most significant decrease being in your mid-thirties. For women who are 35 years of age, there is a 95% chance of pregnancy following unprotected regular sex for three years. This percentage is reduced to 75% in women trying at 38 years of age.



In endometriosis this disorder, the endometrium (lining of the womb) begins to grow in other foreign places, such as the ovaries. This can cause adhesions (bands of tissue clustered together) or cysts (fluid-filled sacs), which interfere with the egg’s release and implantation into the womb.


Pelvic inflammatory disease (PID)

This is an infection of the female upper genital tract, which is formed of the womb, fallopian tubes and ovaries. This infection can injure and scar the fallopian tubes, preventing the egg from travelling into the womb.


Medicines and drugs

Certain medication can have side effects which affect your fertility. These include chemotherapy, antipsychotic drugs, long-term or high dose ibuprofen or aspirin. Illegal drugs such as cocaine and marijuana can also have severe effects on your fertility.

Drugs and infertility

You may not realise, but some medications you take may have a negative impact on your fertility

Common causes of infertility in men:


Abnormal semen

Semen is the ejaculatory fluid which contains the sperm in men. Abnormal semen encompasses: low sperm count, reduced sperm mobility, abnormally shaped sperm. At LDC, our private GP's can facilitate comprehensive semen analysis, if the doctor suspects this may be a cause of infertility. 


Alcohol (men)

Excessive alcohol consumption can negate the quality of your sperm. It is advisable therefore to remain within the 3-4 units of alcohol per day limit recommendation by the Department of Health.

Beer, alcohol, infertility

Excessive alcohol consumption can reduce the quality of a man's sperm, leading to infertility 


How can infertility be treated?

Treatment concerning infertility can be divided into three main categories, examples of each include:

  • Medication: Various drugs are available to aid ovulation in women.
  • Surgery: If the cause of infertility is due to scar tissue in the fallopian tubes in women, surgery may be performed in to repair or remove this scarring.
  • Assisted Conception: In-vitro fertilisation (IVF) involves fertilising the egg outside the body in a laboratory, and then placing it back inside the woman’s womb. Our GP's can refer patients on to private fertility clinics, who can provide this service, if appropriate.
