  • Therapeutic Indications


    Anovulation unresponsive to clomifene citrate
    Controlled superovulation in medically assisted conception programmes


    Treatment should be initiated under the supervision of a physician experienced in the treatment of fertility problems.


    Women with anovulation (including PCOD):
    The object of therapy is to develop a single mature Graafian follicle from which the ovum will be liberated after the administration of human chorionic gonadotrophin (hCG).

    In menstruating patients, treatment should start within first 7 days of the menstrual cycle.

    Treatment should be determined by individual response as assessed by measuring (i) follicle size by ultrasound and/or (ii) oestrogen secretion.

    A commonly used regimen commences at 75 to 150 units daily increasing by 37.5 units (up to 75 units) at 7 or preferably 14 day intervals if necessary to obtain an adequate, but not excessive response. The daily dose is then maintained until pre-ovulatory conditions are reached (usually 7 to 14 days). The maximum daily dose should not be higher than 225 units. If no response after 4 weeks of treatment, that cycle should be abandoned and the patient should recommence treatment at a higher starting dose.

    When an optimal response is obtained, a single injection of 5,000 units up to 10,000 units hCG should be administered 24 to 48 hours after the last urofollitropin injection. The patient is recommended to have coitus on the day of, and the day following, hCG administration. Alternatively, intrauterine insemination (IUI) may be performed.

    If an excessive response is obtained, discontinue treatment, withhold hCG, and recommend barrier contraception or a refrain from coitus until next menstrual bleed. Treatment may then recommence in the next cycle at a lower dose.

    Women undergoing ovarian stimulation for multiple follicular development prior to in vitro fertilisation or other assisted reproductive technologies:
    Down-regulation with a gonadotrophin-releasing hormone (GnRH) agonist is now commonly used in order to suppress the endogenous LH surge and to control tonic levels of LH. In a commonly used protocol, urofollitropin administration is started approximately 2 weeks after the start of agonist treatment, both being continued until adequate follicular development is achieved. For example, following 2 weeks of treatment with an agonist, 150 to 225 units of urofollitropin are administered for the first 7 days. The dose is then adjusted according to the ovarian response.

    A commonly used regimen for superovulation involves the administration of 150 to 225 units urofollitropin daily, commencing on day 2 or 3 of the cycle. Treatment is continued until adequate follicular development has been achieved (as assessed by monitoring of serum oestrogen concentrations and/or ultrasound examination), with the dose adjusted according to the patient's response, to usually not higher than 450 units daily. In general, adequate follicular development is usually achieved on average by the tenth day of treatment (range of 5 to 20 days).

    When an optimal response is obtained, a single injection of 5,000 units up to 10,000 units hCG is administered 24 to 48 hours after the last urofollitropin injection to induce final follicular maturation.


    For subcutaneous or intramuscular injection only.
    Not all brands are licensed for both routes of administration.
    Self-administration (subcutaneous route only) of urofollitropin should only be performed by patients who are well-motivated, adequately trained and with access to expert advice.

    Precautions and Warnings

    Predisposition to thromboembolic disease
    Polycystic ovarian syndrome

    Treat other endocrine disorders and causes of infertility first
    Treatment to be prescribed under the supervision of a specialist
    Rotate injection sites to minimise the risk of lipoatrophy
    Self-admin. - only if adequately trained and have access to expert advice
    Use only if the solution is clear and colourless
    Exclude other causes of infertility before commencing treatment
    Monitor ovarian response using ultrasound prior to and during treatment
    Close medical supervision during initial dosing
    Examine patients complaining of abdominal/pelvic pain for ovarian cysts
    Monitor urinary oestrogens, plasma estradiol + follicle diameter in women
    Pregnancy: Increased risk of multiple pregnancies
    Discontinue immediately if ovarian hyperstimulation occurs
    In cases of OHSS withhold hCG & use barrier contraception for 4 days

    Patients undergoing stimulation of follicular growth are at increased risk of developing ovarian hyperstimulation. Adherence to recommended dosage and regimen of administration, and careful monitoring of therapy will minimise the incidence of such events. Ovarian hyperstimulation syndrome (OHSS) can rapidly progress (24 hours to several days) to become a serious medical event, therefore patients should be followed for at least 2 weeks after human chorionic gonadotropin (hCG) administration.
    The possibility of ovarian hyperstimulation must be taken into consideration in women presenting with pain in the lower abdominal region, possibly in combination with dyspnoea, oliguria, nausea, vomiting, diarrhoea, weight gain and mild to moderate enlargement of ovaries and ovarian cysts.
    In serious, but rare cases, an ovarian hyperstimulation syndrome with clearly enlarged ovaries, can go hand in hand with possible accumulation of fluid in the abdomen or thorax as well as more serious thromboembolic complications. Should the above mentioned symptoms occur a careful medical and ultrasound examination is indicated. Clinical evaluation may reveal hypovolaemia, haemoconcentration, electrolyte imbalances, ascites, haemoperitoneum, pleural effusions, hydrothorax, acute pulmonary distress, and thromboembolic events. Very rarely, severe OHSS may be complicated by pulmonary embolism, myocardial infarction and ischaemic stroke.

    OHSS may be more severe and more protracted if pregnancy occurs. Most often, OHSS occurs after hormonal treatment has been discontinued and reaches its maximum at about 7 to 10 days following treatment. Usually OHSS resolves spontaneously with the onset of menses.

    If severe OHSS occurs, gonadotrophin treatment should be stopped if still ongoing, the patient hospitalised and specific therapy for OHSS started.

    In ART, aspiration of all follicles prior to ovulation may reduce the occurrence of hyperstimulation.

    The risk of multiple pregnancy following assisted reproductive technologies is related to the number of oocytes/embryos replaced, their quality and the patient age. In patients undergoing induction of ovulation, the incidence of multiple pregnancies and births is increased compared with natural conception. The majority of multiple conceptions are twins.

    Ectopic pregnancy may occur in women with a history of prior tubal disease.

    The incidence of spontaneous miscarriage is higher in patients treated with FSH than in the general population, but it is comparable to the incidence found in women with other fertility problems.

    Pregnancy and Lactation


    Urofollitropin contraindicated in pregnancy.

    Animal experiments do not reveal teratogenicity, and at the time of writing there are no sufficient studies on pregnancy in humans. Schaefer (2007) considers that inadvertent exposure during pregnancy is not an indication for invasive diagnostic procedures or termination.

    The use of all medication in pregnancy should be avoided whenever possible; particularly in the first trimester. Non-drug treatments should also be considered. When essential, a medication with the best safety record over time should be chosen, employing the lowest effective dose for the shortest possible time. Polypharmacy should be avoided. Teratogens taken in the pre-embryonic period, often quoted as lasting until 14 to 17 days post-conception, are believed to have an all-or-nothing effect. Where drugs have a short half-life, and when the date of conception is certain, this may allow women to be reassured where drug exposure has occurred within this time frame. Further advice may be available from the UK National Teratology Information Service (NTIS) and through ToxBase, available via password on the internet ( ) or if this is unavailable at the backup site ( ).


    Urofollitropin is contraindicated in lactation.

    No paediatric concerns reported via milk. FSH is very unlikely to penetrate milk, and it would not be orally bioavailable. However, observe closely for reduced milk production (Medications and Mothers' Milk, 2014).

    Neonates, infants born prematurely, those with low birth weight, those with an unstable gastrointestinal function or who have serious illnesses may require special consideration. For any infant, if a drug is prescribed to the nursing mother, it should be at the lowest practical dose and for the shortest time. When drug administration is unavoidable and breastfeeding is to continue, minimisation of exposure of the infant to the drug may sometimes be achieved by timing the maternal doses to just after a feeding episode. Infants exposed to drugs via breast milk should be monitored for unusual signs or symptoms. Interactions between the drug received by the infant from the mother's milk and medication prescribed for the infant should also be considered, for example, when the drug given to the infant may prevent metabolism of the drug received via breast milk.
