Endocrine coordination in rhesus monkeys: female responses to the male
1Research Division, North Carolina Department of Mental Health, Raleigh, NC 27611, USA.
Abstract:
Female rhesus monkeys were captured from the free-ranging colony at La Parguera, Puerto Rico during the non-mating season and paired with testosterone propionate-treated and control males daily for 12 weeks. Testosterone propionate-treated males displayed high levels of sexual behavior and low levels of aggressive behavior compared to control males. Pairing females with such sexually active or inactive males had only minor effects on female sexual behavior and no measurable influence on ovarian cyclicity. These results indicate that sexual activity of males apparently failed to coordinate reproductive changes in females. Reproductive coordination previously reported in females may be due to interactions among females.

Target Cell Response to Hormones
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...

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.
Structures of the Endocrine System
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...
