Overview
Medically induced menopause happens when menopause is triggered by surgery or medical treatment, not by the natural ageing process.
If you have cancer or a health condition such as endometriosis or ovarian cysts, you may need medical treatment or surgery that brings on menopause. Medically induced menopause can be temporary or permanent.

There are lots of ways people describe medically induced menopause. The terms ‘medically induced menopause’ and ‘medical menopause’ are the most common, and they mean the same thing. You might also hear:
Treatment-induced menopause
Chemically induced or chemical menopause
Surgical menopause
Iatrogenic menopause
Early or premature menopause due to medical treatment
Induced or forced menopause
Understanding medically induced menopause
Some women regain their periods and fertility after chemotherapy, radiation or hormone treatments for conditions like cancer or endometriosis. Others may enter permanent menopause. It’s often hard to know how long symptoms will last before treatment, and there’s no test to predict if medically induced menopause will be temporary or permanent.
Every person is different, so it’s important to speak with your health care team. Your doctors can assess your individual circumstances and help you understand what’s most likely in your case.
Injections to create a temporary menopause are key treatments for a wide range of conditions.
The injections are called gonadotrophin-releasing hormone (GnRH) analogue injections. They stop your ovaries making the hormones oestrogen and progesterone, and stop your menstrual cycle.
You may be prescribed GnRH injections to help manage symptoms of:
endometriosis
adenomyosis
uterine fibroids
heavy periods
pelvic pain
premenstrual dysphoric disorder (PMDD).
If you’ve not been through menopause, ovulation and periods usually come back within 6 to 10 weeks after stopping treatment with GnRH.
The longer the treatment time, the longer it might take for your periods to return.
Oestrogen levels start to rise again after the last injection wears off. That means your menopausal symptoms might also improve.
The older you get while you take the treatment, the closer you get to your natural menopause. You may find you’re in perimenopause when you stop treatment. If you’ve been through natural menopause while taking the treatment, your periods will not come back.
Chemotherapy and radiation therapy induced menopause
Your individual circumstances will affect whether your chemotherapy or radiation treatment causes a temporary or permanent earlier menopause, and how soon after treatment it starts.
The following factors can make it more likely that your periods and fertility return after chemotherapy.
Being aged under 35
The younger you are, the more likely you’re to have more eggs in your ovaries. One study suggested over 70% of women under 35 got their periods back – the study included women between the ages of 20 to 35 whose periods stopped during treatment.
Some sources suggest women under 45 may get their periods back 2 years after treatment.
The type and dose of chemotherapy drugs
Some chemotherapy drugs are less damaging to the ovaries (gonadotoxic) than others. Having the least damaging medicine types, lower doses and a lower number of medicines as part of your treatment can also increase the chance of chemotherapy menopause being temporary.
Your health condition
Sometimes, lower doses of chemotherapy are used for conditions including lupus and rheumatoid arthritis.
Here are some key factors to consider and talk through with your health care team.
Your age when you have treatment
The older you are, the closer you’re likely to be to your natural menopause. This means you have fewer eggs in your ovaries already. The chance of medically induced menopause being permanent increases with age.
Having chemotherapy and radiation therapy
If you have chemotherapy as well as radiation therapy to the belly (abdomen), pelvis or whole body, it is more likely to cause permanent menopause.
The type and dose of chemotherapy drugs
Taking medicines that are more damaging to the ovaries (gonadotoxic) than others, taking higher doses, or taking more than one medicine can also increase the chance of chemotherapy menopause being permanent.
These chemotherapy medicines are more likely to cause permanent menopause:
Busulfan
Carmustine
Chlorambucil
Cyclophosphamide
Doxorubicin
Lomustine
Mechlorethamine
Melphalan
Procarbazine
The dose and location of your radiation treatment
Higher doses and radiation directly to your ovaries or pituitary gland (a gland in your brain) are more likely to create permanent menopause.
After radiation treatment, there are things that will increase the chance of your menopause being temporary. These include the following:
Your age
The younger you are, the more egg cells you’re likely to have in your ovaries. So, even if some get damaged, there may be others that don’t get damaged.
The dose and location of radiation treatment
How much radiation your ovaries absorb is important. Lower doses and radiation that is directed further away from your ovaries can make it more likely for medically induced menopause to be temporary.
How much radiation your pituitary gland absorbs is also important. This gland is located in your brain and tells your ovaries to make oestrogen.
Location of your ovaries (ovarian transportation)
Whether you can ‘move’ your ovaries before radiation treatment. Sometimes it is possible to have minor surgery that moves the ovaries further away from the area where you need radiation treatment. The operation is called ovarian transposition. This operation may help:
reduce damage to your ovaries
prevent medically induced menopause
reduce the chance of induced menopause being permanent.
Surgery induced menopause
Different kinds of surgery can create an earlier menopause or cause menopause to happen straight away. Here’s what the latest research tells us.
Surgical menopause means the removal of both your ovaries. If both ovaries are removed, you’ll experience permanent menopause immediately.
A hysterectomy is an operation to remove your uterus and does not necessarily include the removal of the ovaries. Sometimes, ovary removal is recommended at the same time as a hysterectomy.
If you have a hysterectomy and keep both ovaries, you’re likely to reach menopause at the expected age. However, in some women, a hysterectomy, even without ovary removal, may still lead to earlier menopause.
If you also have one ovary removed with your hysterectomy, there is a higher chance of a natural menopause. There is also a small risk that you may have an immediate menopause after your operation.
You may also reach menopause earlier than you would have without the operation. This may be because blood flow to your ovaries can be affected, or scarring can happen due to the operation.
Usually, removing only the fallopian tubes (an operation called a bilateral salpingectomy) would not cause menopause. But there is some evidence that removing the fallopian tubes during a hysterectomy may increase your chance of menopausal symptoms one year after surgery.
More research is needed in this area.
What to ask your doctor about medically induced menopause
When it comes to medicines and surgery, it’s important to make the right decision for you.
Asking the right questions and getting the information you need from your health care team is a key part of that.
You don’t need to ask all the questions below – use them as a guide and choose what matters most to you.
Questions about surgery and recovery
If you’re considering surgery to treat or reduce your risk of cancer, or to treat a condition such as endometriosis or ovarian cysts, these questions can be helpful to ask your health care team.
