Male Fertility.

Male infertility can result from several factors. Sperm abnormalities can include conditions like azoospermia (no sperm), oligospermia (low sperm count), teratospermia (abnormally shaped sperm), and asthenospermia (poor motility or sperm that don’t swim effectively).

Some common causes include:

• Sperm production issues: Associated with hormonal abnormalities, chromosomal or genetic abnormalities, or testicular causes

• Blockages or absence of vas deferens: This prevents sperm from traveling through the reproductive tract and can be caused by genetic conditions like cystic fibrosis or injury

• DNA fragmentation: High levels of DNA damage in sperm can reduce their ability to fertilise an egg

• Sperm antibodies: These can impair sperm motility and fertilisation

• Functional issues: Conditions like retrograde ejaculation (where semen flows into the bladder instead of exiting through the penis) or hormonal imbalances can affect fertility

If you suspect any of these issues, Dr Kath recommends a comprehensive fertility assessment to identify and address the underlying cause.

The most important test for male fertility is a semen analysis, which evaluates:

• The number of sperm (count)

• How well they swim (motility)

• Their shape and structure (morphology)

If repeated semen analyses show abnormalities, additional tests like sperm DNA fragmentation analysis, hormonal testing, chromosomal and genetic testing, or imaging may be recommended. Through IVFAustralia, Dr Kath can access state-of-the-art diagnostic tools to give a clear understanding of your fertility health.

Several lifestyle and health factors can impact sperm production and quality, including:

• Smoking and excessive alcohol consumption

• Use of anabolic steroids or recreational drugs

• Obesity and high body mass index (BMI)

• Exposure to toxins such as pesticides or heavy metals

• Prolonged heat exposure (e.g., frequent use of hot tubs, saunas, or tight-fitting underwear)

• Stress, which can interfere with hormone levels needed for sperm production

Maintaining a healthy lifestyle by quitting smoking, limiting alcohol, managing stress, prioritising sleep and avoiding exposure to toxins can significantly improve sperm quality.

While the impact of age on male fertility is less pronounced than in women, there is a decline in sperm quality after age 45. Older men may experience:

• Reduced sperm volume and motility

• Higher rates of DNA fragmentation in sperm

Dr Kath encourages men over 45 years who are trying to conceive to consider a fertility consultation to assess their reproductive health.

Male infertility can often be managed with advanced treatments tailored to individual needs, including:

• Lifestyle modifications: Some advice includes quitting smoking, reducing alcohol, improving diet and exercise, supplementation, weight management and prioritising sleep

• Medications: Hormonal therapies or gonadotrophins to improve sperm production

• Intrauterine insemination (IUI): Sperm is specially prepared and placed directly in the uterus to optimise timing and proximity to an ovulated egg

• IVF with ICSI: Intracytoplasmic sperm injection (ICSI) is used to inject a single sperm into an egg, in cases of abnormal sperm parameters or previous poor fertilisation

• Surgical sperm retrieval: Used to retrieve sperm in cases of blockages or absent sperm in the ejaculate

Retrograde ejaculation occurs when semen flows backward into the bladder instead of out through the penis. This condition can result in little or no semen during ejaculation.

Causes can involve:

• Previous surgery to the bladder or prostate

• Diabetes

• Spinal cord injury

• Medication side effects

Treatment options include:

• Collecting sperm from a urine sample or surgically retrieving it from the testes

• Using assisted reproductive technologies like IUI, IVF, or ICSI to achieve pregnancy

Yes, vasectomy reversals can restore fertility. This involves reconnecting the vas deferens to allow sperm to re-enter the ejaculate. Success rates vary depending on the time since the vasectomy and other factors.

If a reversal isn’t viable, sperm can be surgically retrieved and used in an IVF cycle with ICSI. Dr Kath will guide you in deciding the best approach based on your circumstances and goals.

While not all cases of male infertility can be prevented, there are steps men can take to reduce the risk:

• Maintain a healthy weight and balanced diet

• Avoid smoking, excessive alcohol, and drug use

• Limit heat exposure to the testicles by avoiding hot tubs, saunas, and tight underwear

• Minimise exposure to environmental toxins

• Manage stress and maintain good overall health

• Prioritise sleep

Regular health check-ups and early intervention are also key to optimising fertility. Dr Kath can advise on specific interventions tailored to your personal circumstances.
