What Choragon is and What it is Used For
What Choragon Is
Choragon contains a hormone produced in women called chorionic gonadotrophin. It works by helping reproductive organs to work normally in both women and men.
What Choragon is Used For
In women, Choragon is used for infertility caused by eggs not being produced or released properly (anovulatory infertility).
In men, Choragon is used for:
- Delayed puberty.
- Testicles which have not dropped (cryptorchidism).
- Low sperm count (oligospermia).
Choragon should only be given by a specialist doctor who has the facilities needed to monitor you.
Before Choragon is Given to You
You must not be given Choragon if:
- You have a condition that is made worse by increasing levels of male sex hormones (such as testosterone).
If you are not sure if this applies to you, talk to your doctor, nurse or pharmacist before you are given this medicine.
Take Special Care with Choragon
Check with your doctor, nurse or pharmacist before you are given your medicine if:
- You have asthma.
- You have epilepsy.
- You get migraines.
- You have heart or kidney problems.
- You are allergic to any of the ingredients of the medicine (listed in Section 6). You may be given a skin test first if your doctor thinks that you might have an allergic reaction to Choragon.
If any of the above apply to you (or if you are not sure), talk to your doctor, nurse or pharmacist before you are given Choragon.
How Choragon is Given to You
Choragon will be given to you by a doctor.
- It will be given to you as an injection into a muscle.
- The dose depends on what you are being treated for. The usual doses are given below.
- Before you have Choragon, your doctor will take blood samples to check the level of oestrogen (a hormone) in your blood.
- If your oestrogen is at the right level, you will be given 10,000 units of Choragon.
- It will be given to you in the middle of your menstrual cycle.
For Delayed Puberty
- The usual starting dose is 500 units twice a week.
- During your treatment, your doctor will take blood samples. This is to check the levels of testosterone (a hormone) in your blood. Your doctor may then adjust your dose.
- Treatment normally lasts for 4 to 6 weeks.
For Testicles which Have not Dropped
- Treatment should begin before the child reaches puberty. The best age to start treatment is between 7 and 10 years.
- The doctor will decide how much the child needs and how often they need it.
- The usual starting dose is 500 units three times a week. However, this may be increased up to 4000 units three times a week if necessary.
- Treatment normally lasts for 6 to 10 weeks.
- In males over 17 years of age, a starting dose of 1000 units twice a week can be given. Treatment is normally continued for 1 to 2 months after the testicles have dropped.
For low sperm count
- The starting dose is 500 units two or three times a week.
- During your treatment, your doctor will check semen samples to see how well the treatment is working. Your doctor may then adjust your dose.
- Treatment normally lasts for 16 weeks.
If You are Given too Much Choragon
If you think you have been given too much Choragon, tell your doctor, nurse or pharmacist.
If You Forget to Have Choragon
If you think that you have missed a dose, tell your doctor, nurse or pharmacist.
