Unexplained infertility accounts for 25% of all fertility problems and is a term used when doctors can’t find a cause for infertility after a full series of tests and assessments.
Sometimes, for a small minority of people, that the egg and sperm are ‘incompatible’ so when put together do not form an embryo. However this can be overcome with intracytoplasmic sperm injection (ICSI), an IVF technique in which an individual sperm is introduced directly into an egg cell.
Sometimes being significantly overweight or underweight, exercising excessively or even environmental toxins may be contributing factors to unexplained infertility. Lifestyle improvements, better nutrition and regular unprotected intercourse (twice a week) may be sufficient to conceive.
However, following a lack of conception after two years of trying (including the year before fertility investigations), IVF is usually considered the best option.
Combination infertility is where there are both male and female fertility problems, or when one partner has more than one fertility problem. A combination is diagnosed in about 40% of cases. Symptoms vary, depending on causes, and so do the treatments.
