How might cancer patients preserve their sexuality?

Many cancer patients face sexual problems from cancer treatment. Diminished libido, arousal difficulties, pain, vaginal dryness, erectile dysfunction (ED), and ejaculation trouble are some of the more common effects.

In some cases, patients can make decisions about sexual function when they plan their treatment with their oncology team. The following slides offer some examples.

Testosterone

Testosterone is an important sex hormone for men, as it drives much of their libido and sexual function. Some men feel that their quality of life would suffer if they were not able to experience intimacy the same way as they did before cancer. They might opt for less aggressive cancer treatments that preserve testosterone levels, even if that means their prognosis is poorer.

Nerve-sparing Treatments

Nerves play an essential role in sexuality. When a person is sexually stimulated, nerves carry messages between the brain and the genitals. This starts the arousal process – such as an erection for men or vaginal lubrication for women.

Some cancer treatments, such as radical prostatectomy (surgical removal of the prostate gland) can potentially damage nerves related to sexual function. For example, the prostate gland is surrounded by nerves necessary for erections. In nerve-sparing procedures, surgeons preserve as many nerves as possible to lower the risk of ED.

Hysterectomies and colorectal surgeries may also be done in a nerve-sparing manner.

Nipple-sparing Treatments

Women with breast cancer may choose nipple-sparing mastectomy, which preserves the nipple area. Breasts can then be reconstructed around the nipple. Women may not feel the same nipple sensations as they did before surgery, but keeping the nipples can foster a more positive body image, which contributes to better sexual function.

Keep in mind that there is no one-size-fits-all approach for preserving sexuality after cancer treatment. Patients should ask their doctors what will work best for their personal situation.

While some physical aspects can be addressed, it is still important to maintain healthy intimate relationships with partners and take advantage of products and services that can help maintain sexual function.

For example,

water-based lubricants may make intercourse more comfortable for women with vaginal dryness. Treatments for erectile dysfunction is available, and men should not hesitate to ask about them. (Note: There many approaches to treating sexual problems after cancer, and one’s doctor can provide the best advice.)

Counseling and sex therapy – alone or as a couple – may also be beneficial.

Cancer and Male Fertility

Male cancer, cryopreservation, and fertility

What is the difference between semen and sperm?

This can be confusing since the terms are often used interchangeably in the media and casua conversation.

However, they are very different. Sperm are the male reproductive cells that contain genetic material. A sperm is made up of three main parts: the head, the midpiece, and the tail. Semen is the liquid that is ejaculated and may or may not contain sperm. This liquid is produced by glands in the reproductive system and also contains enzymes and fructose in addition to sperm.

How can cancer treatment affect my ability to have a child?

Chemotherapy or radiation can affect your ability to make sperm or impact the ability of the sperm to fertilize an egg.
The type, location, and duration of the treatment can affect whether those changes are temporary or permanent. For some types of cancer, the reproductive organs are removed or damaged during surgery that is performed to remove the cancer.

Are there options for preserving fertility in men who have been newly diagnosed with cancer?

Yes! Sperm can be collected and frozen for later use before cancer treatment is started. This way, you may be able to have children after your treatment. This process is called
cryopreservation or freezing. The kind of cancer you have and the treatments you will receive can determine what your options are.

What is involved in sperm collection?

For many men, collecting sperm to freeze is a simple, noninvasive procedure. You will be shown to a private room, asked to masturbate to orgasm, and collect your semen in a special container.
A usual semen sample will contain around 5-20 million sperm per milliliter and is able to be divided into several vials for storage. Often, since sperm production is affected by many factors, you may be asked to collect more than one sample. This helps to improve your chances of being able to have a child later.

What if I can’t give a sample?

Some men are unwilling or unable to collect a sample through masturbation. For these men, a special condom may be used to collect semen during intercourse.
Other men have a blockage in their reproductive tract; as a result, no sperm are found in their semen. Sperm can be obtained through various procedures that remove them
directly from the testicle or reproductive tubes located beside the testicles.
Some men may have a condition that causes sperm and some or all of the semen to collect in the bladder instead of being released through the tip of the penis. For those men,
sperm can often be collected from the urine after intercourse.
If a man is unable to ejaculate (release semen durin orgasm), there are options. Sperm can be surgically removed from the testicles and injected directly into an egg in a process called intracytoplasmic sperm injection (ICSI).

If a man is not able to ejaculate due to spinal cord injury, vibratory stimulation or electroejaculation can be used.

How is sperm cryopreserved?

Once collected, the semen sample is mixed with cryoprotectants. These are liquids that help protect the sperm against damage during freezing and thawing. The sample is then frozen by a slow-cooling method or a flash freezing method called vitrification.

How long can sperm be stored?

Sperm can be stored indefinitely. Sperm that have been frozen for over 20 years have been used to create pregnancies. Testicular tissue cryopreservation Because very few sperm are necessary to fertilize an egg in a dish, it is possible to obtain sperm directly from the testicle. In cases where very few sperm are produced, this may be the best option. Additionally, some patients have
not yet reached a point of puberty where they have sperm in their ejaculate. It is important to note that it will be necessary to have intracytoplasmic sperm injection (ICSI) when using testicular sperm.

When a boy has not begun to make mature sperm, options are limited. In some research centers across the world, samples of testicular tissue are removed and frozen. When
it’s time to attempt pregnancy, the tissue is examined for stem cells. Stem cells are cells that have the potential to develop into many different kinds of cells. The hope is to
isolate these few cells and mature them into functional sperm. So far, animal research is promising and human studies are ongoing. It is important to remember that this is
an experimental procedure and whether it will be successful is not known.

Conclusion

The most important thing to remember about fertility preservation is that it should be done prior to any cancer treatment if possible. This will give you the best chance of having usable sperm.
