Infertility is defined as the inability to conceive after a couple has engaged in regular, unprotected sexual intercourse. It’s a surprisingly common issue, affecting approximately 1 in 7 couples who are trying to start a family.
For couples where the woman is under the age of 40, over 80% will successfully conceive naturally within one year of consistent, unprotected sex – typically defined as every two to three days. However, for those who have been trying for more than three years without success, the chances of natural conception within the following year decrease significantly, to 1 in 4 or even less.
When to Seek Professional Advice
While some couples conceive very quickly, for others, the journey can be longer and more challenging. If you have been actively trying to get pregnant for a year without success, it is advisable to consult a healthcare professional.
It’s particularly important for women aged 36 and over, or individuals with pre-existing knowledge of potential fertility issues, to seek medical advice sooner rather than later. A doctor can conduct initial investigations to identify common underlying causes of fertility problems and suggest appropriate treatments and interventions.
Infertility is generally diagnosed when a couple has not achieved pregnancy after one year of actively trying. There are two primary classifications of infertility:
- Primary Infertility: This refers to individuals who have never conceived before and are experiencing difficulty in achieving their first pregnancy.
- Secondary Infertility: This applies to individuals who have had one or more successful pregnancies in the past but are now facing challenges in conceiving again.

Exploring Treatment Options for Infertility
Fortunately, there are various effective treatments available to address infertility. These options range from medical interventions to surgical procedures and assisted reproductive technologies. Common fertility treatments include:
- Medical Treatments for Ovulation Disorders: These medications are designed to regulate or stimulate ovulation in women who are not ovulating regularly or at all.
- Surgical Procedures: Surgery may be recommended to correct structural issues that impede fertility, such as endometriosis, blocked fallopian tubes, or scar tissue (adhesions) within the uterus or abdominal cavity.
- Assisted Conception Technologies: These advanced techniques include Intrauterine Insemination (IUI), where sperm is directly placed into the uterus, and In Vitro Fertilization (IVF), where eggs are fertilized with sperm in a laboratory and then implanted in the uterus.
The specific treatment plan will be tailored based on the underlying cause of infertility, individual circumstances, and the services available through your local healthcare providers. Private fertility treatment is also an option; however, it can be costly and success is not guaranteed. If considering private treatment, it’s essential to choose a reputable clinic licensed by the Human Fertilisation and Embryology Authority (HFEA) and to seek advice from your general practitioner.
It’s also important to be aware that some fertility treatments, particularly IVF, carry potential risks and complications. These can include:
- Multiple Pregnancy: IVF treatments that involve implanting multiple embryos increase the likelihood of a multiple pregnancy (twins or more), which elevates the risk of complications for both the mother and babies.
- Ectopic Pregnancy: There is a slightly increased risk of ectopic pregnancy (where the fertilized egg implants outside the uterus) associated with IVF.
Further information on available treatments can be found in resources detailing how infertility is treated.
Uncovering the Causes of Infertility
Pinpointing the exact cause of infertility can be complex. Fertility issues can stem from either partner, and in approximately 25% of cases, the underlying cause remains unidentified.
Common factors contributing to infertility include:
- Ovulation Problems: Irregular or absent ovulation (the monthly release of an egg) is a frequent cause of infertility in women.
- Semen Quality Issues: Low sperm count, poor sperm motility (movement), or abnormal sperm morphology (shape) can hinder fertilization.
- Fallopian Tube Blockage or Damage: Blocked or damaged fallopian tubes prevent the egg from traveling to the uterus and sperm from reaching the egg.
- Endometriosis: This condition involves tissue similar to the uterine lining growing outside the uterus, which can interfere with fertility.
Identifying Risk Factors for Infertility
Several lifestyle and environmental factors can also negatively impact fertility. These risk factors include:
-
Age: Fertility naturally declines with age in both men and women, but particularly significantly for women as they approach their late 30s and beyond.
-
Weight: Being overweight or obese (with a BMI of 30 or higher) is associated with reduced fertility in both sexes. In women, being overweight or severely underweight can disrupt ovulation.
-
Sexually Transmitted Infections (STIs): Certain STIs, such as chlamydia, can cause pelvic inflammatory disease and damage reproductive organs, leading to infertility.
-
Smoking: Smoking, including passive smoking, significantly reduces fertility in both men and women. It negatively impacts egg and sperm quality and overall conception rates. Resources are available to help with quitting smoking.
-
Alcohol Consumption: For women trying to conceive, the safest approach is to abstain from alcohol completely. Excessive alcohol consumption can also impair sperm quality in men. Health guidelines generally recommend limiting alcohol intake to no more than 14 units per week, spread over several days.
-
Environmental Toxins: Exposure to certain environmental factors, such as pesticides, solvents, and heavy metals, has been linked to reduced fertility, especially in men.
-
Stress: While the direct impact of stress on fertility is still being researched, high stress levels can disrupt relationships, reduce libido, and in severe cases, may affect ovulation and sperm production. Resources are available for managing stress.
It’s important to remember that seeking help is a positive step. Consulting with a healthcare professional is crucial for understanding potential causes and exploring the best path forward on your journey to parenthood.
