Ovulation Stimulation

Ovulation Stimulation

Follicle-stimulating hormone (FSH):

The hormone used to stimulate multiple eggs. FSH is given by daily injection and sold as Gonal-f®, Follistim®, Repronex®, and Bravelle®. The dose and the number of days vary depending on follicle development.


Ultrasound uses sound waves to make sonar pictures of the abdomen. We use a series of ultrasound scans to obtain a three-dimensional picture of the ovaries and to follow follicle growth in the ovary. Through ultrasound, we can observe follicle growth, number, size, and maturity. This allows us to time hCG administration. Ultrasound may be performed abdominally or vaginally and is painless. There have been no reported harmful effects on developing eggs or on early pregnancy.
