The divorce rate after radical prostatectomy — the surgery performed to treat prostate cancer — remains relatively low in Australia, estimated at around 7–10% within five years post-surgery, only slightly above the national average.
While most couples stay together, many experience temporary emotional strain due to post-surgical effects such as erectile dysfunction, psychological distress, and changes in intimacy. These factors can lead to communication breakdowns that, in some cases, evolve into functional or legal separation.
From a legal perspective, Australia’s Family Law Act 1975 (Cth) recognises that serious medical conditions can influence both the grounds for divorce and the division of assets or maintenance claims following separation. Thus, while radical prostatectomy does not directly cause divorce, its emotional, physical, and financial consequences often shape how couples — and courts — navigate the aftermath of illness within marriage.
The Legal and Medical Context Behind Post-Prostatectomy Relationships
Under Australian law, marriage is not only an emotional union but a legal partnership governed by the Family Law Act 1975 (Cth). When one partner experiences a major illness or disability — such as complications following a radical prostatectomy — both parties’ legal and financial obligations can shift substantially.
A radical prostatectomy involves the surgical removal of the prostate gland, typically as part of early-stage prostate cancer treatment. While the procedure boasts strong survival rates, it often affects:
- Sexual function (due to nerve or vascular injury)
- Urinary control and continence
- Emotional wellbeing and self-image
These physical and psychological changes can have legal significance. In cases where separation follows treatment, courts often consider health status when assessing spousal maintenance, earning capacity, and contributions to the marriage, especially if one spouse became a caregiver.
What the Evidence Says: Divorce Rate After Radical Prostatectomy
According to recent clinical research from The Journal of Urology and Psycho-Oncology, around 7–10% of couples divorce within five years of a radical prostatectomy — marginally above Australia’s age-adjusted national average of roughly 5%.
However, this increase is not considered statistically significant. The data shows that most couples remain together but face periods of emotional or physical distance. The critical legal insight is that divorce rates alone don’t capture the true impact — many couples remain legally married while experiencing functional separation, particularly when communication and intimacy deteriorate.
From a family law perspective, this distinction matters. Functional separation — where the marriage continues in form but not in substance — is often cited in affidavits of separation under one roof during divorce proceedings. Such scenarios are increasingly common among couples recovering from major medical treatment.
Why Does Relationship Strain Occur After Radical Prostatectomy?
Relationship strain after radical prostatectomy primarily arises from the combined effects of physical, emotional, and financial changes that alter how partners connect and communicate after surgery. While the procedure often succeeds medically, it can disrupt key aspects of intimacy and daily life that sustain a marriage — sometimes leading to emotional or even legal separation.
1. Loss of Sexual Function and Intimacy
The most common cause of marital tension post-surgery is erectile dysfunction. Even with modern nerve-sparing techniques, recovery of sexual function may take 12 to 24 months, and in some cases may not return fully.
This change often shifts intimacy from spontaneous to medically assisted, leading some couples to experience embarrassment or emotional distance. In family law proceedings, such prolonged withdrawal from marital relations is sometimes cited as evidence of irretrievable breakdown or functional separation under one roof.
2. Psychological and Emotional After-Effects
Men who undergo prostate removal frequently report depression, anxiety, or diminished self-esteem, while partners may experience compassion fatigue or frustration. Without open communication, these issues can escalate into isolation or resentment.
Legally, emotional distress may influence post-divorce assessments of spousal maintenance, particularly where a medical condition limits earning capacity or contributes to mental-health-related hardship.
3. Financial and Lifestyle Pressures
Extended recovery time, reduced work hours, and ongoing medical costs can place strain on household finances. For couples already facing mortgage or family commitments, this economic pressure can compound emotional stress.
In the context of Australian family law, courts routinely consider these financial realities when determining property settlements and future-needs factors under section 75(2) of the Family Law Act 1975 (Cth).
4. Shift in Relationship Roles
Post-operative recovery often reverses roles — with the partner becoming a caregiver and the patient feeling dependent. This dynamic can erode equality within the relationship if not balanced by empathy and shared decision-making. In severe cases, it may form part of a legal claim relating to contributions as a carer during property division or maintenance proceedings.
In summary, relationship strain after radical prostatectomy occurs because the surgery transforms physical health into a multidimensional challenge — affecting emotional stability, financial security, and relational identity. Addressing these issues early through counselling, medical rehabilitation, and legal advice can significantly reduce the risk of marital breakdown.
Comparative Insights: Divorce Rates and Other Cancer Treatments
Research comparing prostatectomy outcomes to other cancer treatments reveals nuanced gender dynamics. Men recovering from prostate cancer are statistically less likely to be divorced or abandoned by their partners than women undergoing breast or cervical cancer treatment.
A study by the University of Michigan Health System found that male cancer survivors had divorce rates around 10%, whereas female survivors’ divorce rates reached 20–25%.
This difference reflects sociocultural norms — female caregiving resilience versus male avoidance of emotional caregiving — but it also informs family law counselling practices and spousal maintenance assessments in Australia.
Legal Implications When Separation Follows Treatment
If a couple separates following prostate cancer treatment, several legal dimensions arise:
- Grounds for Divorce: Australia operates under a no-fault divorce system. The only requirement is proof of 12 months’ separation, even if the couple remained “under one roof” during treatment.
- Spousal Maintenance: Courts may grant periodic or lump-sum maintenance where medical complications reduce a party’s ability to earn. A prostatectomy patient with long-term side effects could qualify for additional support.
- Property Settlement: Health issues can affect asset division under section 79 of the Act. Courts may weigh caregiving roles, medical expenses, and future earning potential when determining equitable distribution.
- Superannuation and Insurance: Post-surgery incapacity can impact superannuation splitting and life-insurance entitlements. Legal practitioners often liaise with trustees to ensure compliance with Family Law (Superannuation) Regulations 2001 (Cth).
- Medical Privacy: Health records are protected under the Privacy Act 1988 (Cth). However, in family-law proceedings, limited disclosure of medical information may be necessary where health directly influences financial capacity or parenting arrangements.
In short, the intersection between health and family law demands precision — emotionally sensitive yet procedurally rigorous representation.
Support Services and Legal Guidance for Couples

Frequently Asked Questions
Even with clinical and legal knowledge, couples often face uncertainty about rights, responsibilities, and risks. Below are answers to the most common questions about divorce and relationship outcomes after radical prostatectomy.
Does radical prostatectomy increase the risk of divorce?
Not significantly. The divorce rate rises only marginally compared with national averages. However, prolonged emotional withdrawal, intimacy loss, and untreated mental-health challenges can contribute to functional or legal separation.
What factors cause relationship strain after prostate surgery?
Key causes include loss of sexual function, depression, financial stress, and partner fatigue. Many of these are treatable through therapy, rehabilitation, and open communication — interventions that often prevent separation.
Are divorce rates higher than other cancer treatments?
No. Prostate cancer survivors generally experience lower divorce rates than survivors of female-specific cancers. However, the emotional burden on couples remains substantial, warranting early psychosocial and legal support.
How can couples maintain intimacy and stability post-surgery?
Professional counselling, physical therapy, and transparent communication are essential. From a legal perspective, clear documentation of caregiving arrangements and shared financial planning can also protect both parties if separation later occurs.
What legal steps should be taken if separation follows treatment?
Seek immediate advice from a family lawyer experienced in health-related separations. They can assist with property settlement, maintenance applications, and procedural compliance with the Family Law Act 1975 (Cth).
Final Legal Perspective
While the divorce rate after radical prostatectomy remains relatively low, the emotional and financial consequences of the surgery can still strain marriages.
Australian law recognises these complexities — providing mechanisms for maintenance, fair property division, and compassionate resolution where health changes the dynamics of a relationship.
For couples navigating this stage, the most important step is not legal action but early professional engagement — combining medical rehabilitation, relationship counselling, and legal advice to safeguard both emotional wellbeing and financial security. Platforms like LegalFinda connect individuals with experienced family lawyers who can provide the guidance and clarity needed to manage post-surgery relationship and financial challenges with confidence.
