Male fertility evaluation primarily involves a semen analysis, commonly known as a sperm test, to assess sperm health and quality. The examination evaluates key parameters, including sperm concentration, motility, morphology (size and shape), and overall sperm quality. Before undergoing a semen analysis, patients are advised to get adequate rest, abstain from ejaculation for at least 2–3 days, and avoid alcohol, smoking, and recreational drugs to help ensure accurate test results.
This can be due to various factors, including genetic defects, hormonal imbalances, or conditions like varicocele, which is the enlargement of veins within the scrotum.
Conditions such as blockages in the vas deferens or epididymis can prevent sperm from being ejaculated.
Infertility screening in our Bangkok clinic can determine whether a patient has low levels of hormones such as testosterone, which can affect sperm production.
Conditions like Klinefelter syndrome, where men have an extra X chromosome, can impact fertility.
Smoking, excessive alcohol consumption, drug use, obesity, and exposure to environmental toxins can all affect sperm quality and quantity.
Infections such as epididymitis or sexually transmitted infections (STIs) can cause scarring that blocks sperm passage.
is a primary test done to evaluate sperm count, motility, and morphology. This test helps understand the quantity and quality of sperm. The patient will also undergo a hormonal evaluation involving blood tests to check levels of hormones such as testosterone, luteinizing hormone (LH), and follicle stimulating hormone (FSH), which play crucial roles in sperm production.
In cases where genetic factors might be involved, tests such as karyotyping or Y chromosome microdeletion may be conducted. Imaging tests such as a scrotal ultrasound may also be needed to detect issues like varicocele or blockages in the reproductive tract.
