Spermatogenesis Induction (Follistim AQ Single-Use Vial or Cartridge)
Subcutaneous (Adults) Pretreat with hCG prior to use of Follistim AQ; once normal serum testosterone levels achieved, give 450 IU/week (as 225 IU twice weekly or 150 IU 3 times weekly) with hCG; continue for at least 3–4 mo.

- Monitor follicular maturation during therapy via ovarian ultrasound and serum estradiol levels.
- Assess for ovarian enlargement (abdominal distention, abdominal pain). Usually regresses without treatment within 2–3 weeks. Assess patient for signs of ovarian hyperstimulation syndrome (severe ovarian enlargement, abdominal pain and distention, nausea, vomiting, weight gain, diarrhea, dyspnea, oliguria). May be accompanied by ascites, pleural effusion, hypovolemia, electrolyte imbalance, hemoperitoneum, thromboembolic events.

- Prior to initiation of therapy discuss with patient the duration of therapy, required monitoring, potential adverse reactions, and risk of multiple births.
- Encourage couple to have intercourse daily, beginning on the day prior to administration of hCG until ovulation becomes apparent based on indices to determine progestational activity. Care should be taken to ensure insemination.
- Advise patient to notify health care professional if worsening or strong abdominal pain occurs or if any side effect that is persistent or bothersome occurs.
