Understanding Male Reproduction and Common Causes of Infertility: How Dr. Rachael Knight Can Help

Male infertility can result from a variety of factors, many of which are treatable. Here are the most common causes:

1. Low Sperm Count (Oligospermia)
   Low sperm count is one of the most common causes of male infertility. It means there are not enough sperm in the ejaculate to fertilize an egg. Sperm count can be affected by various factors, including genetics, health conditions, and lifestyle choices. A sperm count lower than 15 million sperm per milliliter of semen is typically considered low.
2. Poor Sperm Motility (Asthenozoospermia)
   Even with a normal sperm count, sperm motility can be compromised, meaning the sperm struggles to swim toward and penetrate the egg. Motility problems can be due to genetic factors, infection, or lifestyle factors like smoking, alcohol, or excess weight.
3. Abnormal Sperm Morphology (Teratozoospermia)
   Sperm morphology refers to the shape and size of sperm. Abnormalities in sperm shape can prevent sperm from effectively reaching and fertilizing the egg. This issue often coexists with low motility or low sperm count, and can be due to environmental factors, genetic conditions, or lifestyle habits.
4. Varicocoele
   A varicocoele is an enlargement of veins within the scrotum that can interfere with sperm production and quality. This condition, which is similar to varicose veins in the legs, is quite common and can be treated surgically if it is contributing to infertility.
5. Hormonal Imbalances
   Male fertility is heavily dependent on a balanced hormone system. Conditions like hypogonadism (low testosterone) or high levels of prolactin (a hormone produced by the pituitary gland) can disrupt sperm production. Hormonal imbalances can be caused by genetic issues, pituitary gland disorders, or certain medications.
6. Obstructions or Structural Issues
   Sometimes, blockages in the vas deferens (the tube that carries sperm) or other parts of the reproductive tract can prevent sperm from being released during ejaculation. These obstructions could be due to injury, infection, or congenital abnormalities.
7. Erectile Dysfunction
   Though not directly related to sperm quality, erectile dysfunction (ED) can make it difficult for men to engage in sexual intercourse and thus conceive. ED can be caused by psychological issues, chronic health problems (such as diabetes or high blood pressure), or lifestyle factors.
8. Lifestyle Factors
   Environmental and lifestyle factors can significantly impact male fertility. Smoking, vaping, excessive alcohol use, poor diet and exposure to environmental toxins (like pesticides, heavy metals, or radiation) can all lower sperm count, motility, and morphology. Additionally, prolonged exposure to heat (from hot tubs, saunas, or tight clothing) can affect sperm production.
9. Age
   While male fertility doesn’t decline as rapidly as female fertility with age, it can still be affected. As men age, sperm quality may decrease, leading to lower motility and an increased risk of chromosomal abnormalities, which can impact conception and the health of the child.

If you or your partner are facing challenges with conception, Dr Rachael Knight’s clinic, Life Fertility Melbourne, offers a range of services designed to diagnose and treat male infertility. Here’s how she can help:

1. Comprehensive Fertility Assessment
   Life Fertility Clinic Melbourne’s laboratory offers detailed fertility testing for men, including semen analysis, which evaluates sperm count, motility, and morphology. Hormone testing, genetic screening, and physical examinations also help identify underlying issues contributing to infertility.
2. Lifestyle and Health Optimisation
   Dr Rachael Knight offers advice on improving lifestyle factors that can boost fertility. This may include guidance on nutrition, exercise, stress management, and cutting out harmful substances like tobacco and alcohol. In some cases, supplements or medical treatments may be prescribed to enhance sperm health.
3. Surgical Interventions
   For men with structural issues like a varicocoele or blockages in the reproductive tract, Dr Rachael Knight provides access to surgical options to improve sperm production and improve fertility outcomes. Varicocoele surgery may enhance sperm count and quality in many cases.
4. Sperm Retrieval Techniques
   In cases where sperm production is severely impaired or blocked, sperm can sometimes be retrieved directly from the testicles or epididymis using procedures like TESE (Testicular Sperm Extraction) or PESA (Percutaneous Epididymal Sperm Aspiration). These techniques allow sperm to be collected and used in assisted reproduction treatments such as IVF. In some cases the assistance of a microscope is required and this is known as Micro-TESE.
5. Intrauterine Insemination (IUI)
   For couples where ED is an issue, IUI can be an effective treatment. In this procedure, sperm is washed and concentrated before being directly inserted into the woman’s uterus during ovulation. This improves the chances of sperm reaching the egg.
6. In Vitro Fertilization (IVF) and ICSI
   In male infertility, IVF (in vitro fertilization) paired with ICSI (intracytoplasmic sperm injection) is often recommended. ICSI involves injecting a single sperm directly into an egg to facilitate fertilization. This technique has helped countless men with low sperm count, poor motility, or other sperm-related issues achieve pregnancy.
7. Counseling and Emotional Support
   Infertility can be emotionally challenging, and Life Fertility Clinic Melbourne offers counseling services to support men and couples through the process. From navigating treatment decisions to handling the emotional stress, Dr Rachael Knight and her team provides comprehensive support throughout your fertility journey.
