PMOS (PCOS) & Fertility

Polyendocrine Metabolic Ovarian Syndrome (PMOS), formerly known as Polycystic Ovary Syndrome (PCOS), is one of the most common causes of fertility challenges. It affects how the ovaries function and can impact ovulation, hormone balance, and overall reproductive health.

With Dr Daniel Lantsberg, PMOS is a core area of expertise. With a structured and personalised approach, many patients with PMOS are able to successfully conceive with the right treatment and support.

What is PMOS?

PMOS is a hormonal condition that affects how the ovaries work. It is often associated with irregular menstrual cycles, difficulty ovulating, and elevated levels of certain hormones.

Common features of PMOS include:

  • Irregular or absent menstrual cycles
  • Difficulty ovulating regularly
  • Increased levels of androgens (male hormones)
  • Polycystic-appearing ovaries on ultrasound

Not all patients will experience all symptoms, and the condition can vary significantly in severity.

How PMOS Affects Fertility

The main way PMOS affects fertility is through irregular or absent ovulation.

Without regular ovulation:

  • Eggs are not released consistently
  • Timing of conception becomes unpredictable
  • Natural conception can be more difficult

 

In addition, hormonal imbalances associated with PMOS may affect:

  • Egg development and quality
  • The uterine environment
  • Metabolic factors that influence reproductive health

While these factors can make conception more challenging, they can often be effectively managed with appropriate treatment.

Symptoms and When to Seek Advice

PMOS may be suspected if you experience:

  • Irregular or infrequent periods
  • Difficulty conceiving
  • Acne or excess hair growth
  • Weight gain or difficulty maintaining weight
  • A previous diagnosis of PMOS

If you have been diagnosed with PMOS or suspect it may be affecting your fertility, early assessment can help guide appropriate treatment.

Diagnosing PMOS

Diagnosis is based on a combination of clinical history, blood tests, and ultrasound findings.

This may include:

  • Hormone testing to assess ovarian function and androgen levels
  • Pelvic ultrasound to evaluate ovarian appearance
  • Assessment of menstrual cycle patterns

Diagnosis is individualised, and not all patients will meet the same criteria.

Treatment Options for PMOS

PMOS is one of the most treatable causes of infertility, and many patients achieve successful pregnancy outcomes with the right approach.

Treatment depends on your individual situation and may include:



This is the most common and effective first-line treatment for PMOS-related infertility.

Medications are used to stimulate ovulation, helping the ovaries release eggs more regularly. Careful monitoring ensures that treatment is safe and optimised for success.

For some patients, identifying and optimising ovulation timing can improve the chance of natural conception.

In some cases, addressing underlying metabolic factors can improve ovulation and overall fertility outcomes.

This may include:

  • Weight management strategies
  • Nutritional guidance
  • Managing insulin resistance where relevant

IUI may be considered in selected cases, often in combination with ovulation induction.

IVF and Fertility Treatments

If initial treatments are not successful or not appropriate, IVF may be recommended.

IVF allows for:

  • Controlled stimulation of the ovaries
  • Retrieval and fertilisation of eggs
  • Selection of embryos for transfer

It is a highly effective option for many patients with PMOS.

 

PMOS and Egg Quality

While PMOS primarily affects ovulation, it can also influence egg development.

With appropriate treatment and careful monitoring:

  • Egg development can be optimised
  • Risks associated with ovarian stimulation can be managed
  • Treatment outcomes can be significantly improved

Long-Term Considerations

PMOS is a lifelong condition, and its effects extend beyond fertility.

Patients with PMOS may have an increased risk of:

  • Insulin resistance
  • Type-2 diabetes
  • Cardiovascular health issues

Addressing these factors as part of your fertility care can improve both reproductive and long-term health outcomes.

A Personalised Approach to PMOS Care

No two patients with PMOS are the same. Treatment is tailored based on:

  • Your symptoms and hormone profile
  • Your fertility goals and timeline
  • Your response to treatment
  • Any associated metabolic factors

With Dr Daniel Lantsberg, care is individualised to ensure the most effective and appropriate approach for each patient.
