What does Zoladex do to ovaries?

So Zoladex causes the ovaries to temporarily shut down. By doing this while a woman is being treated with chemotherapy, the goal is to help protect the eggs from the chemotherapy medicine. Doctors call treatments given after surgery to reduce the risk of the cancer coming back (recurrence) adjuvant treatments.

What is the mechanism of action of Zoladex?

Zoladex is classified as a luteinizing hormone releasing hormone (LHRH) agonist. LHRH agonists work by telling the pituitary gland located in the brain to stop producing luteinizing hormone, which (in men) stimulates the testicles to release testosterone and (in women) stimulates the ovaries to release estrogen.

Does Zoladex shut down your ovaries?

Medications that shut down the ovaries temporarily include Zoladex (chemical name: goserelin) and Lupron (chemical name: leuprolide). These are taken by injection, and they shut down the ovaries about 2-4 weeks after the first injection.

How is ovarian suppression done?

Ovarian suppression uses drug therapy or surgery to prevent the ovaries from making estrogen. This stops menstrual periods and lowers hormone levels in the body (similar to a natural menopause), so the tumor can’t get the estrogen it needs to grow.

Do you ovulate while on Zoladex?

When GnRH is blocked, no ovulation occurs. So Zoladex causes the ovaries to temporarily shut down. By doing this while a woman is being treated with chemotherapy, the goal is to help protect the eggs from the chemotherapy medicine.

Does Zoladex affect fertility?

When Zoladex is used in fertility treatment (IVF), the available evidence shows that it does not cause any abnormalities in egg development, or on the outcome of any pregnancy that results from the treatment.

What hormones does Zoladex block?

Goserelin is a type of hormone therapy called luteinising hormone blocker. This means it stops the release of luteinising hormone (LH) from the pituitary gland. Hormones are natural substances made by glands in our bodies. Blocking LH stops the ovaries from making oestrogen.

Does Zoladex increase fertility?

Zoladex Helps Preserve Fertility in Women With Early-Stage, Hormone-Receptor-Negative Breast Cancer Treated With Chemotherapy. Many women diagnosed with breast cancer, especially younger women, are concerned about their ability to have children after treatment.

Do you still produce estrogen after ovaries are removed?

Until menopause, the ovaries make most of your body’s estrogen. When your ovaries are removed (oophorectomy) during a hysterectomy, your estrogen levels drop. Estrogen therapy (ET) replaces some or all of the estrogen that your ovaries would be making until menopause.

How long does it take Zoladex to wear off?

The small pellet containing Zoladex 3.6 is about the size of a grain of rice. After the pellet is injected, it slowly dissolves and releases Zoladex 3.6. Each pellet takes about 4 weeks (28 days) to dissolve completely. By four weeks, almost all the Zoladex 3.6 is gone and has been used by the body.

What are the side effects of ovarian suppression?

Ovarian suppression therapy can be either permanent (via surgical removal of the ovaries) or temporary (via the use of medications). The most common side effects are related to the temporary or permanent menopause that is created, including hot flashes, mood swings, and vaginal dryness.
