For married couples who have lived together for years but still don\u2019t have children, it may signal infertility. Medical evaluation is needed to identify the cause and plan treatment for subfertility.<\/p>\n

Therefore, to build a clearer understanding of infertility\u2014especially in men\u2014this article explains common causes and how to check for early signs.<\/p>\n

 <\/p>\n

What causes infertility?<\/strong><\/h2>\n

 <\/p>\n

Male infertility can result from many factors. The most common include:<\/p>\n

 <\/p>\n

Advancing age<\/strong><\/p>\n

 <\/p>\n

From about age 40 onward, male sex hormones decline, which can reduce both sperm count and sperm quality.<\/p>\n

 <\/p>\n

Obesity<\/strong><\/p>\n

 <\/p>\n

Excess body weight or obesity can impair reproductive function and reduce fertility.<\/p>\n

 <\/p>\n

Smoking<\/strong><\/p>\n

 <\/p>\n

Nicotine increases free radicals that damage cells and body systems, including the male reproductive system, and lowers sperm quality and count.<\/p>\n

 <\/p>\n

Alcohol consumption<\/strong><\/p>\n

 <\/p>\n

Alcohol interferes with absorption of vitamins and minerals, affecting reproductive efficiency and reducing the number of healthy sperm.<\/p>\n

 <\/p>\n

Caffeine-containing drinks<\/strong><\/p>\n

 <\/p>\n

Beverages with caffeine, such as tea or coffee, can negatively affect the reproductive system and reduce sperm quantity.<\/p>\n

 <\/p>\n

Abnormalities of the reproductive organs<\/strong><\/p>\n

 <\/p>\n

Structural problems in the reproductive tract\u2014such as abnormalities of the vas deferens\u2014can cause infertility.<\/p>\n

 <\/p>\n

Hormonal imbalance affecting sperm production<\/strong><\/p>\n

 <\/p>\n

Male sex hormones play a key role in regulating sperm (and egg) production. Imbalances can lead to infertility.<\/p>\n

 <\/p>\n

Viral infections and illness-related side effects<\/strong><\/p>\n

 <\/p>\n

Certain infections, especially those involving the reproductive tract, can impair fertility. Some illnesses and their treatments may also contribute to subfertility.<\/p>\n

 <\/p>\n

History of severe injury<\/strong><\/p>\n

 <\/p>\n

Serious trauma affecting reproductive organs or nearby areas may lead to male infertility.<\/p>\n

 <\/p>\n

\"Semen<\/p>\n

What does male infertility look like? What should you look for?<\/strong><\/h2>\n

If a couple wonders whether the male partner is infertile, note that infertility usually can\u2019t be identified by appearance alone. A semen analysis is required to assess sperm number and concentration.<\/p>\n

 <\/p>\n

How to evaluate male infertility<\/strong><\/h2>\n

 <\/p>\n

There are several ways to evaluate male infertility, but the most accurate and widely used test is semen analysis interpreted by a specialist. The analysis assesses:<\/p>\n

 <\/p>\n

    \n
  1. Semen volume \u2014 the amount ejaculated<\/li>\n
  2. Sperm count \u2014 the number of sperm per milliliter of semen<\/li>\n
  3. Sperm motility \u2014 how well the sperm move<\/li>\n
  4. Sperm morphology \u2014 the physical shape and structure of the sperm<\/li>\n<\/ol>\n

     <\/p>\n

    Preparation steps before a semen analysis<\/h3>\n

     <\/p>\n

      \n
    1. Before undergoing semen analysis, prepare as follows:<\/li>\n
    2. Get adequate rest before the test day.<\/li>\n
    3. Abstain from sex or ejaculation for at least 2\u20133 days before the test.<\/li>\n<\/ol>\n

       <\/p>\n

      Steps during semen analysis<\/h3>\n

       <\/p>\n

        \n
      1. Collect the sample: the patient ejaculates into a sterile container provided by the hospital.<\/li>\n
      2. Submit the container to staff for laboratory analysis.<\/li>\n
      3. Consult the physician for results. If abnormalities indicate infertility, discuss a treatment plan for subfertility.<\/li>\n<\/ol>\n
