Definition - What does Follistim mean?
Follistim is an injectable medication from a class of medications called gonadotropins that is a synthetic form of human follicle-stimulating hormone (FSH) used to treat infertility in men and women. A primary function of FSH is to influence sex cell differentiation and development.
In women, Follistim is used to promote the release of eggs for egg retrieval as part of an in vitro fertilization (IVF) or egg donation procedure. Follistim also is used to aid infertility in women who do not ovulate easily on their own.
Follistim is used to promote spermatogenesis (sperm creation) in men with gonadotropin-releasing hormone (GnRH) deficiency. Men with this disorder often have abnormally small male sex organs (testes), a condition known as hypogonadotropic hypogonadism.
Follistim is also known as Follitropin Beta.
FertilitySmarts explains Follistim
Follistim is injected subcutaneously (under the skin) or intramuscularly (IM) depending on the formulation. For women undergoing IVF, it is usually given for the first 4-7 days of treatment. For women who are using it for ovulation induction without IVF, Follistim is given for at least the first 7 days of the cycle.
For men with hypogonadotropic hypogonadism, Follistim is given twice to three times weekly for 3 to 4 months until normal testosterone levels have been reached. Follistim is often used in combination with other fertility medications.
The most common side effects include headache, injection site redness or pain, and abdominal discomfort. In men, Follistim may cause breast enlargement or acne. In women, Follistim may cause multiple births or a condition called ovarian hyperstimulation syndrome (OHSS). Women should contact their doctor immediately if they have extreme abdominal bloating or pain up to two weeks following taking the medication.
