Infertility is a medical condition that is diagnosed when a couple has been unable to achieve pregnancy despite regular, unprotected sexual intercourse for a certain period of time. The specific timeframe for diagnosing infertility varies based on factors such as age and individual circumstances. In general, if a woman is under 35 years old, infertility is typically diagnosed after one year of unsuccessful attempts at conception. However, for women aged 35 and above, the timeframe is shortened to six months due to the natural decline in fertility with age.

It is important to note that infertility can affect both men and women, and the causes can be attributed to either partner or a combination of factors. The prevalence of male and female infertility is similar, with each accounting for approximately one-third of cases, while the remaining cases are classified as unexplained infertility.

Causes of infertility in women can include:

1. Ovulation Disorders: Conditions such as polycystic ovary syndrome (PCOS), hormonal imbalances, or problems with the functioning of the ovaries can affect the release of mature eggs.
2. Fallopian Tube Blockage or Damage: Issues such as pelvic inflammatory disease (PID), endometriosis, or previous pelvic surgeries can cause blockages or damage to the fallopian tubes, hindering the fertilization of the egg.
3. Uterine or Cervical Abnormalities: Structural abnormalities within the uterus or cervix can impact implantation or the passage of sperm into the uterus.
4. Age-related Factors: As a woman ages, the quantity and quality of her eggs decline, leading to diminished fertility and an increased risk of chromosomal abnormalities.
5. Other Factors: Medical conditions such as thyroid disorders, autoimmune diseases, or certain genetic conditions can also contribute to infertility in women.

Causes of infertility in men can include:

1. Sperm Disorders: Issues such as low sperm count, poor sperm motility (movement), or abnormal sperm shape (morphology) can reduce the chances of successful fertilization.
2. Testicular Disorders: Conditions affecting the testes, such as varicocele (enlarged veins within the scrotum), hormonal imbalances, or genetic disorders, can impact sperm production.
3. Obstruction or Ejaculation Issues: Blockages or abnormalities within the reproductive tract can impede the release of sperm during ejaculation.
4. Medical Conditions and Lifestyle Factors: Certain medical conditions, such as diabetes, obesity, or chronic infections, as well as lifestyle factors like smoking, excessive alcohol consumption, or drug use, can negatively affect sperm quality and fertility.

Both men and women may also experience unexplained infertility, where no specific cause can be identified despite thorough medical evaluations.

The diagnosis of infertility often involves comprehensive medical histories, physical examinations, and specialized tests, which may include hormonal assessments, imaging studies, semen analysis, or reproductive evaluations. Once a diagnosis is established, various treatment options are available depending on the underlying cause and individual circumstances. These can range from lifestyle modifications and medication to assisted reproductive technologies (ART), such as in vitro fertilization (IVF) or intrauterine insemination (IUI).

It is recommended that couples experiencing difficulties in conceiving seek medical evaluation and guidance from fertility specialists or reproductive endocrinologists who can provide personalized care and support throughout the fertility journey.
