growth hormone + human pituitary follicle-stimulating hormone + GnRH antagonist

This is a combination therapy used in fertility treatments, particularly for assisted reproductive technologies like in vitro fertilization (IVF). The combination consists of three components with distinct functions: 1. **Growth hormone**: Enhances ovarian response to stimulation 2. **Human pituitary follicle-stimulating hormone (FSH)**: Stimulates the development of ovarian follicles 3. **GnRH antagonist**: Prevents premature ovulation by blocking gonadotropin-releasing hormone receptors This combination is typically used in controlled ovarian stimulation protocols for patients undergoing IVF, particularly those who may be poor responders to standard stimulation protocols.
