Cancer treatments can be life-saving, but they may also affect fertility, leaving many concerned about their ability to have children after recovery. Fortunately, advancements in reproductive medicine now offer a range of options for to preserve and restore fertility. This article explores the fertility preservation and treatment options available for those who wish to achieve parenthood post-cancer.
How cancer treatments affect fertility
Cancer treatments like chemotherapy, radiation, and surgery can impact fertility depending on several factors, including the type of treatment, the patient’s age, and the specific cancer involved. Some common effects on fertility include:
Chemotherapy
Certain chemotherapy drugs may damage eggs in women or reduce sperm production in men.
Radiation therapy
Radiation, when targeted near the pelvic area, can harm reproductive organs and impair fertility.
Surgery
Surgical removal of reproductive organs - such as ovaries in women or testicles in men - can result in infertility.
Hormonal therapy
Treatments that alter hormone levels may disrupt reproductive function, affecting the overall ability to conceive.
How to preserve fertility before cancer treatment
For individuals diagnosed with cancer who have yet to start treatment, fertility preservation can be an important consideration. These methods aim to safeguard fertility before exposure to potentially harmful therapies.
Egg freezing (oocyte cryopreservation)
One of the most common fertility preservation techniques for women.
- Hormonal stimulation is used to produce multiple eggs, which are retrieved and frozen for future use. These eggs can later be thawed, fertilised through in-vitro fertilisation (IVF), and implanted in the uterus.
Egg freezing is ideal for women who are not ready to conceive but want to preserve their fertility for the future, and are about to undergo treatments that may impair fertility, such as chemotherapy or radiation.
- Procedure: It takes about 10-14 days of hormonal stimulation followed by a minor surgical procedure to retrieve the eggs.
Embryo freezing
Similar to egg freezing, embryo freezing involves stimulating the ovaries to produce eggs. However, in this process, the eggs are fertilised with sperm to create embryos, which are then frozen for future use.
- This is suitable for women who have a partner or are planning to use donor sperm.
Ovarian tissue freezing
Part of the ovarian tissue is surgically removed and frozen in this process. After cancer treatment, the tissue can be re-implanted into the body, potentially restoring fertility.
- This is suitable for women who may not have time for hormonal stimulation and egg retrieval before cancer treatment begins.
Gonadal shielding
This technique is used to protect reproductive organs from radiation during cancer treatment. Shields are placed over the ovaries or testicles during radiation to reduce exposure and prevent damage.

What are the fertility options after cancer treatment
Cancer treatments, such as chemotherapy, radiation, or surgery, can significantly affect fertility. However, even if fertility preservation was not pursued before treatment, there are still viable options to achieive parenthood available after recovery.
In-Vitro Fertilisation (IVF)
For women who have undergone cancer treatment but still have viable eggs, IVF can be an effective path to conception. In IVF, eggs are retrieved, fertilised in the lab, and the resulting embryos are implanted into the uterus. This option is also available to women who may have frozen eggs or embryos before their cancer treatment.
Donor eggs
Individuals or couples may opt to use donor eggs or sperm, if cancer treatment has led to infertility. Donor eggs can be fertilised using the partner’s or donor’s sperm through IVF.
Surrogacy
If a woman is unable to carry a pregnancy to term due to cancer treatment, surrogacy may be a viable option. This involves having another woman carry the pregnancy using the individual’s own embryos or donor embryos.
Understanding hormonal health and fertility post-treatment
It is important to consult a fertility specialist after completing cancer treatment to assess your hormonal and reproductive health. For women, this may include tests to evaluate egg reserves, or hormone replacement therapy if reproductive hormones are affected. For men, sperm analysis can help determine sperm count and quality.
A comprehensive fertility evaluation helps determine suitable options, whether that involves natural conception, IVF, or other assisted reproductive techniques.
