Male Infertility
Male infertility occurs when a man has difficulty contributing to a successful pregnancy. During fertilisation, a sperm must travel and reach a woman's egg to create an embryo. However, various issues can prevent this from happening. Common causes of male infertility include hormonal imbalances, blockages in the reproductive organs, and a low sperm count or poor sperm quality.
Diagnosis of male infertility typically involves a thorough medical history, physical examination, and semen analysis to identify any underlying issues. Factors such as health, lifestyle, and environment can also impact fertility.
Symptoms and Causes
Male infertility often has no obvious symptoms, and men may only discover their condition when trying to conceive with their partner. However, some warning signs include:
Difficulty conceiving with a fertile partner after a year of unprotected intercourse
Semen analysis showing low sperm count or poor motility
Testicular or scrotal pain, swelling, or lumps
Erectile dysfunction or difficulty maintaining an erection
Loss of facial or body hair, indicating hormonal imbalances
Painful ejaculation or ejaculatory issues
Past medical conditions or treatments that could impact fertility
Family history of infertility or genetic disorders affecting fertility
Low Sperm Count (Oligospermia)
A low sperm count is one of the main causes of male infertility. It can result from hormonal imbalances, genetic defects, infections, or conditions like varicocele.
Poor Sperm Motility
Sperm need to swim effectively to reach and fertilize an egg. Poor motility can be caused by hormonal issues, genetic defects, or damage to the reproductive system.
Abnormal Sperm Shape (Teratozoospermia)
Abnormally shaped sperm can reduce fertilization rates. This can result from genetic defects, infections, or environmental toxins.
Reproductive System Obstructions
Blockages in the tubes from the testicles to the penis prevent sperm ejaculation. Infections, inflammation, or scarring from surgeries or injuries can cause these obstructions.
Varicocele
Enlarged veins in the testicles can lead to reduced sperm production and quality, contributing to infertility.
Hormonal Imbalances
Problems with hormone production or regulation can cause infertility. Conditions like thyroid disorders or hypogonadism may be responsible.
Genetic Defects
Genetic conditions such as Klinefelter syndrome, Y chromosome deletions, or cystic fibrosis can affect sperm production and function.
Medical Conditions
Diseases like diabetes, high blood pressure, or sexually transmitted infections can exacerbate infertility.
Lifestyle Factors
Smoking, excessive alcohol consumption, drug use, and exposure to environmental toxins are significant contributors to male infertility.
