  • All current treatments for prostate cancer result in increased rates of sexual dysfunction, which can include decreased desire, decreased semen volume, fertility issues, erectile dysfunction, decreased body satisfaction and relationship issues.

  • Men who rate their degree of distress about sexual dysfunction as greater, report poorer quality of life following prostate cancer treatment.
This may sound like bad news, but there is hope, and many men go on to lead satisfying sex lives following treatment. Keep reading for more information.

How does treatment affect sexual function?

Erectile Dysfunction
Different types of prostate cancer treatment affect sexual function in different ways. Surgery, hormone therapy, external beam radiotherapy, brachytherapy, high-intensity-focused ultrasound and cryotherapy can damage nerves and blood vessels, resulting in erection problems.
Sexual Desire
Hormone therapy causes decreased sexual desire (libido), due to a drop in testosterone.

Weight gain, breast swelling and penis shrinkage can occur following treatment. Consequently, some men struggle with negative body image, which can diminish sexual desire.

Also, it’s common to feel tired, stressed and “down” during cancer treatment and post-treatment. These feelings can affect relationships and libido.
Orgasms are still possible following treatment, but they may feel different.

During and after treatment, patients sometimes notice a decrease is semen. Men undergoing radical prostatectomy will no longer ejaculate during orgasm, as the prostate and seminal vesicles responsible for making some of the fluid in the semen are removed. This is called “dry orgasm”.

Patients having surgery for an enlarged prostate (transuretheral resection of the prostate or radiotherapy) may find that semen isn’t ejaculated immediately during orgasm, but rather is passed later during urination.

Other changes may include pain during orgasm, leakage of urine during orgasm, and shortened erections and orgasms.
Some men experience infertility for the reasons listed above or because radiation therapy has affected their ability to produce sperm. Patients who want to have children in the future may wish to store sperm, so that it can be used later for fertility treatment.
