Novarel, Pregnyl, Profasl
Human Chorionic Gonadotropin (hCG), is sold under the brand names Novarel, Pregnyl and Profasi. It is a natural hormone produced by pregnant women in the placenta and extracted from the urine. hCG is typically used to trigger ovulation in a cycle where gonadotropins or hMG is used to induce ovulation – it’s often referred to as the trigger shot.
How it Works
Similar in chemical structure and function to LH, hCG helps with the final maturation of the eggs and triggers ovulation. In addition, HCG stimulates your corpus luteum to secrete progesterone and prepare the lining of your uterus for implantation of the fertilized egg. The hCG injection is usually only once in a cycle, and the timing will be based on factors including blood work and ultrasound. Ovulation usually occurs about 36 hours after hCG is administered.
Most patients only need one hCG injection, which may require upwards of six ampules of the medication.
Each ampules of hCG can cost between $35 and $75 each. The number of ampules needed may differ by patient and by cycle.
