Abstract:
One of the chief findings in polycystic ovaries syndrome may be the defective luteal phase of the menstrual cycle. There is a growing list of publications indicating a defective progesterone production by granulosa cells of ovarian follicles. In consequence, women with polycystic ovaries often require both the luteal phase and early pregnancy supplementation. From different routes of progesterone administration during the menstrual cycle, as the most clinically reliable in the early pregnancy either intramuscular or intravaginal route has been recommended.

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...
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.

Routes of Drug Administration: Overview
Enteral administration refers to drugs absorbed through the gastrointestinal tract. They can be swallowed (perorally), placed under the tongue (sublingually), or on the inner lining of the cheeks (buccally). Perorally administered drugs take time to be absorbed and have a slower onset of action. The rectal route is another form of enteral administration, which allows for...
