Frequently asked questions

When should you not use Chorapur?

It should not be used if there is an allergy to the ingredients of the medicine, a brain or pituitary tumor, cysts or cancer of the ovaries, uterus, or breasts, unexplained vaginal bleeding, ectopic pregnancy within the last 3 months, severe phlebitis or thrombosis, or ovarian hyperstimulation syndrome (OHSS). In men, hormone-dependent tumors are a contraindication.

How should Chorapur be taken?

The medicine is administered by a doctor via intramuscular injection. The dosage depends on the indication and the age of the patient (e.g., in men undergoing infertility treatment, 1 vial of 1500 IU is used twice a week). The doctor's instructions must always be strictly followed.

What side effects may occur after administering Chorapur?

The most common symptoms are headache, injection site reactions, nausea, abdominal pain, vomiting, and enlargement of the mammary gland in men. Ovarian hyperstimulation syndrome (OHSS) may also occur, manifesting, among other things, as abdominal pain, bloating, nausea, or in severe cases, difficulty breathing. Any allergic reactions, such as rash, itching, or throat swelling, must be reported to a doctor immediately.

Does Chorapur interact with other medicines?

There are no known interactions between this medicine and other preparations.

Should special caution be exercised when using the medicine?

Yes. The doctor should be informed about heart disease, kidney disease, epilepsy, and migraine-type headaches. You should also mention an increased risk of thrombosis, overweight, or a family history of thrombotic diseases. In boys before puberty, skeletal development should be monitored.

1. What Chorapur is and what it is used for

Chorapur belongs to a group of medicines called gonadotropins (sex hormones). In women, it controls the release of egg cells from the ovaries, and in men, it regulates the production of the male hormone testosterone.
Chorapur contains the active substance human chorionic gonadotropin (hCG) (a protein hormone), which is obtained from the urine of pregnant women and purified. Gonadotropins play a key role in fertility and reproduction.

In women
In female infertility, this medicine may be used to induce ovulation (ovulation induction). Chorapur is also used together with other medicines to support egg cell development in assisted reproductive technology programs (in vitro fertilization treatment).

In men
Chorapur is used in men for the treatment of low sperm count.
Chorapur may be used alone or in combination with other gonadotropins (hMG, FSH). Chorapur is also used in men prior to initiating stimulation therapy to assess testicular function when reproductive organs do not function properly due to lack of sex hormones.

In children
Chorapur is used in children to treat delayed puberty and in children whose testes have not descended or have not fully descended into the scrotum.

2. Important information before using Chorapur

When not to use Chorapur:

  • if the patient is allergic to human chorionic gonadotropin or any of the other ingredients of this medicine (listed in section 6);
  • if the patient has a brain or pituitary gland tumour;
  • if the female patient has ovarian cysts or enlarged ovaries due to causes other than polycystic ovary syndrome;
  • if the female patient has vaginal bleeding of unknown cause;
  • if the female patient has been diagnosed with ovarian, uterine or breast cancer;
  • if the female patient has had an ectopic pregnancy within the last three months;
  • if the female patient has severe inflammation of the veins or blood clots in the veins (active thromboembolic disorders);
  • if the female patient has ovarian hyperstimulation syndrome (OHSS);
  • if normal pregnancy development is not possible, e.g. in cases of ovarian failure, congenital abnormalities of the reproductive organs preventing pregnancy development, uterine fibroids, or if the female patient has experienced early menopause;
  • if the male patient has been diagnosed with or is suspected of having hormone-dependent tumours such as prostate cancer or (male) breast cancer;
  • if it is known that undescended testes cannot be treated with hormones (e.g. inguinal hernia, previous inguinal surgery, or abnormal testicular location).

Warnings and precautions
Before starting treatment with Chorapur, discuss this with your doctor or nurse.
Inform your doctor if you currently have or have ever had any of the following conditions, as they may worsen after using Chorapur:

  • heart disease;
  • kidney disease;
  • epilepsy;
  • migraine-like headaches.

Treatment with Chorapur may increase the risk of thrombosis. Thrombosis is the formation of blood clots in blood vessels, usually in the veins of the legs or lungs. Pregnancy itself may also increase the risk of thrombosis. Before starting treatment with Chorapur, inform your doctor if:

  • the patient knows they have an increased risk of thrombosis;
  • the patient or a close family member has previously experienced thrombosis;
  • the patient is overweight.

Before starting treatment, it is essential to determine the cause of infertility in the patient or her partner and any factors that might prevent a normal pregnancy. The female patient should undergo a thorough examination to rule out any abnormalities of the reproductive organs or hormonal disorders unrelated to the gonads (e.g. thyroid, adrenal, or pituitary gland disorders).
Close medical supervision during treatment is very important. Regular ultrasound examinations and blood tests are usually performed. This is particularly important because treatment with Chorapur increases the risk of developing ovarian hyperstimulation syndrome (OHSS) (see also section 4 "Possible side effects"). This may occur when the ovaries over-respond to treatment and produce too many follicles. Usually, OHSS resolves spontaneously with the onset of menstruation. However, if pregnancy occurs, OHSS may be more severe and last longer. Therefore, female patients should remain under medical observation for at least two weeks after hCG administration.
Mild or moderate OHSS may cause the following symptoms:

  • abdominal pain or discomfort;
  • abdominal bloating;
  • nausea;
  • vomiting;
  • diarrhoea;
  • weight gain.
    In severe cases of OHSS, additional symptoms may include:
  • difficulty breathing;
  • reduced urine output.
    In very rare cases, severe OHSS may lead to complications such as ovarian torsion or venous or arterial thrombosis. Inform your doctor immediately, even if symptoms appear several days after the last dose of the medicine. These may be signs of excessive ovarian activity, which can be serious. If symptoms worsen, infertility treatment should be discontinued and appropriate treatment initiated in a hospital. Adhering to the recommended dose and careful monitoring of treatment reduces the risk of such symptoms. Female patients with polycystic ovary syndrome have an increased risk of developing OHSS.

After treatment with gonadotropins, the likelihood of multiple pregnancy (twins or more) is higher than with natural conception.
The rate of miscarriage among women who do not produce enough mature oocytes or do not produce them at all, and among women participating in assisted reproductive programmes such as in vitro fertilisation, is higher than in the general population, but comparable to the miscarriage rate among women with other fertility disorders.
Women with damaged fallopian tubes have a slightly increased risk of ectopic pregnancy.
The frequency of congenital abnormalities after fertility treatment may be slightly higher than in naturally conceived pregnancies. This may be related to parental factors (e.g. maternal age, sperm quality) and the higher frequency of multiple pregnancies.
If the patient has a clinically significant medical condition that could worsen during pregnancy, the doctor will provide special monitoring during treatment.
Chorapur may cause a false-positive pregnancy test result for up to 10 days after administration.
Use of Chorapur may lead to positive results in anti-doping tests. Using Chorapur for doping purposes may endanger health.

Children
Chorapur should be used with caution in prepubertal boys to avoid bone problems or premature sexual development. Bone maturation should be monitored regularly.

Chorapur with other medicines
Inform your doctor about all medicines the patient is currently taking or has recently taken, as well as any medicines the patient plans to take.
No interactions with other medicines are known.

Pregnancy, breastfeeding and fertility
If the patient is pregnant or breastfeeding, suspects she may be pregnant, or is planning to have a baby, she should consult her doctor before using this medicine.
Chorapur is indicated for the treatment of infertility (see section "What Chorapur is and what it is used for").
Chorapur must not be used during pregnancy or breastfeeding.

Driving and operating machinery
No studies have been conducted on the effect of Chorapur on the ability to drive or operate machinery. It is expected that Chorapur has no or negligible influence on the ability to drive and operate machinery.

Chorapur contains sodium
Chorapur contains sodium, but the amount does not exceed 1 mmol (23 mg) per 1 ml of solvent, meaning the medicine is considered almost "sodium-free".

3. How to use Chorapur

This medicine should always be used as directed by the physician. If in doubt, consult your
doctor.
Method of administration:
This medicine is administered as an intramuscular injection by a physician experienced
in the treatment of fertility disorders.
Chorapur 1500 IU
Treatment with Chorapur should be conducted by a physician experienced
in the treatment of fertility disorders.
The recommended dose for men is 1 vial twice a week (corresponding to 3000 IU per week).
Since spermatogenesis takes approximately 74 days, treatment should be continued for at least
3 months to expect any improvement. During treatment, the physician monitors
testosterone levels. An increase in the dose of the medicine may be necessary.
If the response to treatment with Chorapur alone is insufficient, the physician may
decide to administer another medicine simultaneously with Chorapur. In some cases,
after achieving improvement using a combination of these medicines, maintenance may be continued using Chorapur alone.
Use in children
Treatment for undescended testes should be completed by the time the child reaches 1 year of age.
The recommended dose for infants is: 250 IU/dose (0.17 ml from a vial containing 1500 IU) twice
weekly for a period of five weeks.
Chorapur 5000 IU
Treatment with Chorapur should be conducted by a physician experienced
in the treatment of fertility disorders.
To induce ovulation and stimulate the ovaries:
The recommended dose is 1 vial (5000 IU) or 2 vials (10,000 IU). The medicine should be administered 24 to 48 hours after optimal follicular growth stimulation has been achieved.
If Chorapur is used to induce ovulation following follicular stimulation,
the patient is advised to have sexual intercourse on the day of injection and the day following
the injection.
To evaluate testicular function in cases where reproductive organs do not function properly
due to lack of sex hormones:
The recommended dose is 1 vial (5000 IU) as a single dose.
Use in children
In boys with delayed puberty:
The recommended dose is 1 vial (5000 IU) once weekly for a period of 3 months.
In cases of unilateral or bilateral undescended testes:
The recommended dose is 1 vial (5000 IU) as a single dose.
Use of a higher than recommended dose of Chorapur
Cases of overdose have not been reported. However, overdose may potentially cause ovarian hyperstimulation syndrome (OHSS); see section 2. "Important information before using Chorapur".
Missed dose of Chorapur
Do not administer a double dose to make up for a missed dose. Consult your
physician.
Discontinuation of Chorapur
Consult your physician.

4. Possible adverse reactions

Like all medicines, this medicine can cause adverse reactions, although not everyone will experience them.
Hormonal medicines used in fertility treatment, such as Chorapur, may cause excessive ovarian activity, leading to a condition called ovarian hyperstimulation syndrome (OHSS). Symptoms may include: abdominal pain, abdominal distension, nausea, vomiting, diarrhoea, and weight gain. In severe cases of OHSS, fluid may accumulate in the abdominal cavity, pelvic cavity, and/or pleural cavity, causing difficulty in breathing and reduced urine output. Rare complications reported in severe cases of OHSS include formation of blood clots in blood vessels (thromboembolic disease) and ovarian torsion. If any of these symptoms occur, immediate medical advice must be sought, even if symptoms appear several days after the last dose of the medicine.

Allergic (hypersensitivity) reactions may occur during treatment with Chorapur. Symptoms include: rash, itching, throat swelling, and difficulty breathing. If any of these symptoms occur, immediate medical advice must be sought.
