Why you might freeze your sperm

There are lots of reasons people look to preserve their fertility into the future. One reason is to preserve fertility until after cancer treatment or gender-affirming hormone treatment (GAHT), and another is for people who think their fertility may decline before they are ready to have children.

Sperm can also be frozen as back up for fertility treatment, for people who think their fertility may decline before they are ready to have children, or as ‘insurance’ before a vasectomy.

Access to publicly funded fertility preservation for the retrieval, freezing and long-term storage of sperm is available for people whose fertility will be permanently impaired by publicly funded treatment for medical conditions, such as by cancer treatment or GAHT.

Options for fertility preservation may exist prior to and after cancer treatment, however it is very important that if you have time before you start your treatment, you speak with a fertility specialist - to ensure you have the full picture. Many options for fertility preservation may be funded through the public health system.


Why freeze and store sperm?

Many treatments for cancer or gender-affirming hormone therapy (GAHT) can have the potential to affect your ability to conceive naturally. This risk is influenced by the type and extent of your disease, or the gender affirming treatment being undertaken*.

Sperm can be frozen and stored long-term for people who face losing their fertility due to medical treatments.

*For more information about your individual fertility risk please talk to your Oncologist, Endocrinologist or other appropriate specialist.

The process

Sperm freezing is straightforward and many people will have enough sperm in one ejaculate for several IVF cycles. If there are enough good quality sperm after thawing then the first approach may be to try IUI treatment, keeping some sperm in reserve for IVF later, if IUI is not successful. If you want to consider IUI as an option, you will almost certainly need to freeze three or more semen samples.

When to seek advice early

  • If you have polycystic ovaries, endometriosis, or have been through a cancer diagnosis; we recommend you get in touch quickly so we can talk you through all your options and give you the greatest possible chance of success.
  • If you’re a single woman considering motherhood in the future; it’s best to approach us early and consider egg freezing as this can be an option for you while you have a higher ovarian reserve and healthier eggs.

Woman’s BMI below 19

Even in these modern times, nature knows best. If a woman's BMI falls below 19, the body senses famine and ovulation is switched off to prevent the risk of having a baby with malnutrition. Excessive exercise can reduce body fat and increase muscle mass to a point where periods cease for the same reason. Risk of miscarriage is also increased in women with a low BMI.

BMI’s greater than 30

This can reduce fertility by 50%. Pregnancy for women with a 30+ BMI is often associated with problems such as maternal diabetes, high blood pressure, big babies and increased risk of caesarean section.
