Is low libido a common side effect of leukemia treatment?

Low libido (reduced sexual desire) can happen during and after leukemia treatment, and it’s fairly common. Treatments like chemotherapy, stem cell/bone marrow transplant, and certain supportive medicines can lower sex hormones, cause fatigue, and affect mood each of which may reduce desire. ^{[1] [2]} Emotional stress and body-image changes during cancer care also often contribute to lower interest in sex. ^[3]

Why libido can drop during leukemia treatment

• Hormone changes (hypogonadism): After stem cell or bone marrow transplant, testosterone can drop in men, leading to erectile issues and loss of libido; abrupt menopause in women can reduce desire and cause vaginal dryness and pain. ^{[2] [4]}
• Chemotherapy effects: Some regimens can lower sex hormones and directly reduce sex drive or make sex more difficult. ^[5]
• Fatigue, pain, and body image: Cancer treatments commonly cause fatigue and changes in how people feel about their bodies, which can dampen sexual interest. ^{[1] [3]}
• Emotional factors: Anxiety, depression, and relationship stress are frequent during treatment and can lessen libido. ^[3]

How common is it?

Sexual changes are widely reported among people receiving cancer therapy, including leukemia, with many experiencing decreased desire, arousal difficulties, or satisfaction changes. Studies and survivor experience show that sexual concerns are frequent and warrant attention, regardless of cancer type. ^{[1] [3]} Historical research in leukemia survivors has noted reduced sexual frequency and satisfaction compared with healthy norms, highlighting the need for supportive care.

Practical ways to manage low libido

1) Optimize physical factors

• Check hormones: Ask your clinician about testing testosterone (in men) or estrogen-related status (in women), especially after transplant or intensive chemo. Treating confirmed hypogonadism (low sex hormones) can improve libido and energy. ^[2]
• Manage treatment side effects: Better control of pain, fatigue, sleep problems, and other symptoms can improve sexual interest. ^[1]

2) Address sexual function directly

• For men: First-line options for erectile difficulties include pills that improve blood flow; vacuum devices or other therapies can be considered if pills are not enough. Restoring erectile function often helps desire. ^[2]
• For women: Vaginal moisturizers and lubricants reduce dryness; low-dose local hormonal therapy can be considered when appropriate to ease pain and improve comfort, which may increase desire. Pelvic floor physical therapy and dilator therapy can help with tightness or stenosis after intensive treatments. ^[1]

3) Support emotional and relationship health

• Counseling and sex therapy: Psychosocial support, couples counseling, and sex therapy can reduce anxiety, improve communication, and rebuild intimacy, all of which can raise libido. A biopsychosocial approach works best. ^{[1] [3]}
• Normalize and communicate: Many people experience these changes; open discussion with partners and clinicians helps tailor solutions and lowers stress. ^[1]

4) Timing and gradual return

• Go slow and be flexible: It’s okay to start with non‑penetrative intimacy and rebuild comfort; desire often returns as physical and emotional recovery progresses. Energy typically improves with time after therapy, and sexual activity can gradually increase. [PM13]

When to seek medical help

• Persistent low libido or distress: If reduced desire lasts for months or causes significant strain, ask for referral to a sexual health program with oncology expertise. Dedicated services can coordinate medical, rehabilitative, and counseling support. ^{[6] [7]}
• After transplant or intensive chemo: Request hormone evaluation and guidance on safe sexual activity during and after treatment. Some cancer medicines can be present in bodily fluids; your team can advise on precautions. ^[8]
