Menotrophin Ferring (Menotrophin)

Menotrophin is used in reproductive medicine to stimulate ovarian follicular development and ovulation.

• Infertility due to anovulation: induces follicular growth and ovulation in women who do not ovulate spontaneously.
• Assisted reproductive technology (ART) ovarian stimulation: supports controlled ovarian hyperstimulation protocols for IVF and ICSI cycles.
• Hypogonadotropic hypogonadism: replaces deficient gonadotropins to restore normal ovarian function in women with pituitary insufficiency.

• Menotrophin contains purified human follicle‑stimulating hormone (FSH) and luteinizing hormone (LH) in a fixed ratio. After subcutaneous or intramuscular injection, the hormones bind to their respective receptors on ovarian granulosa and theca cells, activating the adenylate cyclase‑cAMP pathway. This stimulates follicular recruitment, estrogen production, and final maturation, while LH supports the luteinizing surge required for ovulation.

Menotrophin may be associated with a range of adverse reactions, most of which are related to its hormonal activity and injection route.

Common Side Effects

• Injection site pain or erythema: mild discomfort at the injection site.
• Abdominal bloating or discomfort: transient gastrointestinal symptoms.
• Nausea or vomiting: mild to moderate gastrointestinal upset.
• Headache: occasional tension‑type headache.
• Ovarian cyst formation: small functional cysts that resolve spontaneously.

Serious or Rare Side Effects

• Ovarian hyperstimulation syndrome (OHSS): potentially severe fluid shift and thromboembolic risk.
• Multiple pregnancy: increased chance of twins or higher‑order gestations.
• Severe allergic reaction: anaphylaxis, rash, or angioedema.
• Thromboembolic events: rare clot formation associated with OHSS.
• Ectopic pregnancy: rare but serious complication.

When prescribing Menotrophin, clinicians should observe several safety considerations to minimize risks.

• Pregnancy testing: confirm the patient is not pregnant before initiating therapy.
• Monitor ovarian response: perform serial ultrasound and estradiol measurements to adjust dosing.
• Risk of OHSS: watch for abdominal distension, weight gain, or rapid rise in estradiol and modify treatment if needed.
• Allergic reactions: discontinue if signs of hypersensitivity such as rash or breathing difficulty occur.
• Use in cancer patients: avoid unless the benefit outweighs potential hormonal stimulation risks.
• Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Menotrophin can interact with other hormonal agents and medications that affect ovarian function.

Major Interactions (Avoid)

• Concurrent GnRH agonist or antagonist therapy: may blunt the intended gonadotropin response and increase OHSS risk.
• High‑dose estrogen therapy: can suppress endogenous gonadotropin activity and reduce efficacy.

Moderate Interactions (Monitor Closely)

• Oral contraceptives: may diminish ovarian response; consider a wash‑out period before starting Menotrophin.
• Clomiphene citrate: additive ovulation‑inducing effect; monitor for excessive follicular development.
• Anticoagulants: in the setting of OHSS, increased thrombotic risk may require closer monitoring.
