What CHORAPUR is and what it is used for

CHORAPUR belongs to a group of medicines called gonadotrophins (sex hormones). It controls the
release of eggs from the ovaries in women, and controls production of the male hormone
testosterone, in men.
CHORAPUR contains the active ingredient human chorionic gonadotrophin (hCG) (a protein hormone)
which is extracted and purified from the urine of pregnant women. The gonadotrophins play a vital role in
fertility and reproduction.
In Women
In female infertility it can be used to cause women to ovulate (ovulation induction). CHORAPUR is also
used along with other fertility drugs, to help produce eggs in medically assisted reproduction programmes
(IVF treatment).
In Men
CHORAPUR is used in men to help treat low sperm count. CHORAPUR is used either alone or in
combination with other gonadotrophins (hMG, FSH). CHORAPUR is also used in men before a stimulation
treatment to assess the function of the testes where the reproductive organs are not working correctly due to a
lack of sex hormones.
In Children
CHORAPUR is used in children to treat delayed puberty or in children whose testicles have not or not
completely descended into the scrotum .

What you need to know before you use CHORAPUR

Do not use CHORAPUR:
if you are allergic to chorionic gonadotrophin or any of the other ingredients of this medicine (listed in
section 6).


if you have tumours in the brain or pituitary gland.
if you have ovarian cysts or enlarged ovaries (unless caused by polycystic ovarian disease).
if you have bleeding from the vagina where the cause is not known.
if you have been diagnosed with cancer in the ovaries, uterus or breasts.
if you had an ectopic pregnancy within the last three months.
if you are suffering from severe phlebitis (inflammation of the veins) or blood clots in the veins (active
thromboembolic disorders).
if you suffer from ovarian hyperstimulation syndrome (OHSS – over stimulation of the ovaries).
if a normal pregnancy is not naturally possible, e.g. in the case of ovarian failure, malformations of
sexual organs incompatible with pregnancy or fibroids, or if you have experienced an early
if you have known or suspected sex hormone dependent tumours, e.g. prostate cancer or (male) breast
if it is known that the cause of undescended testicle cannot be treated by hormones (inguinal hernia,
condition after surgery in the inguinal region, abnormal position of testicle).

Warnings and precautions
Talk to your doctor or nurse before using CHORAPUR.
Please inform your doctor if you have or have had any of the following conditions as they may be aggravated
by the use of CHORAPUR:
 heart disease
 kidney disease
 epilepsy
 migraine-like headache
Treatment with CHORAPUR may increase the risk of thrombosis. A thrombosis is the formation of a blood
clot in a blood vessel, mostly in the leg veins or the lung. Pregnancy itself may also increase the risk of
thrombosis. Before starting treatment with CHORAPUR, please inform your doctor if:
 you know that you have an increased risk of thrombosis
 you or a close relative of yours already had a thrombosis
 you are overweight
Prior to the treatment, your or your partner’s infertility and possible reasons why a pregnancy may not be
possible are to be identified. You should be examined thoroughly in order to exclude any changes of the
reproductive organs or hormonal disorders which are not connected with the gonads (e.g. disorders of the
thyroid, adrenal or pituitary glands).
During the treatment, close supervision by your doctor is very important. Usually, regular ultrasound
examinations and blood sampling are performed. This is particularly important, since treatment with
CHORAPUR increases your risk of ovarian hyperstimulation syndrome (OHSS) (see also section 4 „Possible
side effects“). This occurs when the egg sacs (ovaries) overreact to the treatment and form too many follicles.
Usually, OHSS resolves itself during a menstruation period. OHSS may be more severe and more protracted
if pregnancy occurs. Therefore, it is recommended that your doctor monitors you for at least two weeks after
hCG administration.
Symptoms of mild or moderate OHSS are:
 Pain or discomfort in the abdomen
 Swelling in the abdomen
 Nausea
 Vomiting
 Diarrhoea
 Weight gain
In severe cases of OHSS additional symptoms may occur such as:
 Difficulty in breathing
 Decreased urination

In very rare cases complications like twisting of egg sacs (ovaries) and blood clots in veins or arteries may
occur with severe cases of OHSS.
Talk to your doctor straight away, even if the symptoms develop some days after the last injection has been
given. These can be signs of high levels of activity in the ovaries which might become severe.
If these symptoms become severe, the infertility treatment should be stopped and you should receive
treatment in hospital.
Keeping your recommended dose and careful monitoring of your treatment will reduce your risk of getting
these symptoms.
Patients with polycystic ovarian disease have an increased risk of getting OHSS.
Pregnancies achieved by using gonadotrophin therapy are more likely to be twin or multiple pregnancies than
normal pregnancies.
The number of miscarriage both in patients who cannot form enough egg cells or even none at all and in
women who undergo medically assisted reproductive programmes, such as IVF, is higher than in the average
population but comparable to the miscarriage rate of women with other fertility disorders.
Women with pre-damaged fallopian tubes have a slightly increased risk of ectopic pregnancy.
The frequency of malformations after pregnancy treatment can be slightly higher than with natural
conception. This can be related to a number of preconditions in the parents (e.g. mother's age, sperm quality)
and to an increased occurrence of multiple pregnancies.
Your doctor will perform special supervision during treatment if you suffer from a clinically significant
illness in which pregnancy could worsen your condition.
CHORAPUR may lead to a false positive pregnancy test for up to 10 days following administration.
The use of CHORAPUR may lead to positive results in drug tests. The use of CHORAPUR for doping
purposes can result in hazard of your health.
CHORAPUR should be used with caution in prepubertal boys to avoid bone problems or premature puberty.
Skeletal development should be monitored regularly.
Other medicines and CHORAPUR
Tell your doctor if you are using, have recently used or might use any other medicines.
Interactions with other medicinal products are unknown.
Pregnancy, breast-feeding and fertility
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your
doctor for advice before taking this medicine.
CHORAPUR is indicated for the treatment of infertility (see section “What CHORAPUR is and what it is
used for” above).
CHORAPUR should not be used during pregnancy and breast-feeding.
Driving and using machines
No studies on the effects on the ability to drive and use machines have been performed. It is expected that
CHORAPUR has no influence on the ability to drive and use machines.
CHORAPUR contains sodium


CHORAPUR contains sodium, but less than 1 mmol (23 mg) sodium per ml solvent, i.e. it is nearly „sodiumfree“.

How to use CHORAPUR

Always use this medicine exactly as your doctor has told you. Check with your doctor if you are not sure.
Method of administration:
This medicine will be given as an injection into the muscle by a doctor experienced in the treatment of
fertility problems.
Treatment with CHORAPUR should be performed by a doctor experienced in the treatment of fertility
In male patients the recommended dose is 1 vial twice a week (corresponding to 3000 IU per week). Because
the development of sperm cells takes about 74 days, treatment should be continued for at least 3 months
before any improvement can be expected. During this treatment your doctor will monitor your testosterone
levels. It may be necessary to increase the dose.
If the response to CHORAPUR alone is not sufficient, your doctor may decide to give you another medicine
at the same time as CHORAPUR. Once an improvement has been achieved using a combination of these
medicines, it may then in some cases be maintained by using CHORAPUR alone.
Use in children
Treatment of undescended testes should finish when the child is 1 year of age.
The recommended dose is 250 IU/dose (0.17 ml of the 1500 IU vial). This medicine will be administered
twice a week for 5 weeks in young infants.
Treatment with CHORAPUR should be performed by a doctor experienced in the treatment of fertility
For triggering ovulation and stimulation of the ovaries:
The recommended dose is 1 vial (5000 IU) or 2 vials (10000 IU). Administration should be performed 24 to
48 hours after optimal stimulation of the ovaries is achieved.
If CHORAPUR is used for ovulation induction following stimulation of the ovaries, it is recommended to
have sexual intercourse on the day of and the day after injection.
For assessment of the function of the testes in cases where the reproductive organs are not working correctly
due to a lack of sex hormones:
The recommended dose is 1 vial (5000 IU) once.
Use in children
In boys with delayed puberty:
The recommended dose is 1 vial (5000 IU) per week over a period of 3 months.
In the absence of one or both testes:
The recommended dose is 1 vial (5000 IU) once.
If you use more CHORAPUR than you should
No cases of overdose have been reported. However, it is possible that an overdose can cause an ovarian
hyperstimulation syndrome (OHSS), see section 2 “What you need to know before you use CHORAPUR”.

If you forget to use CHORAPUR
Do not take a double dose to make up for a forgotten dose. Talk to your doctor.
If you stop using CHORAPUR
Talk to your doctor.

Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.
Hormones used in the treatment of infertility such as CHORAPUR may cause high levels of activity in the
ovaries leading to a disease called ovarian hyperstimulation syndrome (OHSS). Symptoms may include: pain
in the abdomen, swelling of the abdomen, nausea, vomiting, diarrhoea and weight gain. In cases of severe
OHSS, accumulation of fluid in abdomen, pelvis and/or chest cavity, difficulty in breathing, decreased
urination may also occur. Formation of blood clots in blood vessels (thromboembolism) and twisting of
ovaries (ovarian torsion) have been reported as rare complications in cases of severe OHSS. If you
experience any of these symptoms contact your doctor immediately, even if they develop some days after the
last injection has been given.
Allergic (hypersensitivity) reactions may occur with the use of CHORAPUR. Symptoms may include: rash,
itching, swelling of the throat and difficulty in breathing. If you experience any of these symptoms, contact
your doctor immediately.
The assessment of the side effects is based on the following grades of frequency:
Very common: may affect more than 1 in 10 people
Common: may affect up to 1 in 10 people
Uncommon: may affect up to 1 in 100 people
Rare: may affect up to 1 in 1,000 people
Very rare: may affect up to 1 in 10,000 people
Not known: frequency cannot be estimated from the available data.
Very common
 Enlargement of male mammary glands (gynaecomastia)
 Headache
 Reactions and pain at the injection site
 Nausea, abdominal pain, vomiting
 Mild to moderate ovarian hyperstimulation syndrome (OHSS), breast swelling, pain in testis
 Hot flush (only seen in men)
 Rash (exanthema), inflammation of the sebaceous glands (acne vulgaris)
 Diarrhoea
 Impaired excretion of salts and water
 Severe ovarian hyperstimulation syndrome (OHSS)
 Depression, irritability, restlessness
Not known:
