Abstract:
To reduce cycle cost and patient/staff stress in an ongoing in vitro fertilization (IVF) program, we have utilized a modified "programmed" (PP) follicle stimulation protocol with limited monitoring. We have compared our PP results with those using a conventional, individualized, and fully monitored protocol (OP) in order to show that PP does not compromise the quality of care. Hormonal presuppression made possible an arbitrary starting day for the cycle. In 80% of the cycles, oocyte retrieval (OR) was performed on the planned day or 1 day later. There was no statistically significant difference between the two regimens in oocyte/embryo numbers, quality or pregnancy rates. The cycle cost was significantly reduced. In addition, patient stress was lessened because of the reasonable predictability of cycle timing. We conclude that PP has significant financial and emotional advantages for the patient over OP but does not appear to diminish the chance for pregnancy in an IVF cycle. PP also allows program staff to manage time more effectively, thereby reducing staff stress.

Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH release.
Ovarian Cycle
Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
