The facts

Female & Male HormonesFemale Sex HormonesThe ovaries secrete two hormones, oestrogen and

progesteroneMale Sex Hormones Testosterone & determines the primary and

secondary sex characteristics. The male reproductive system is controlled by

hormones from the hypothalamus and from the anterior pituitary gland.

Female Reproductive System

Hormonal control of the female reproductive cycle.The two cycles are the ovarian cycle and

the uterine cycle. The cycles are interrelated and average 28 days.

The ovarian cycle is divided into the follicular phase and the luteal phase.

During the follicular phase the ovarian follicle matures primarily in response to FSH. The follicular phase ends with ovulation and is dominated by oestrogen.

The uterine cycle is divided into the menstral phase, the proliferative phase and the secretory phase.

Menstral – loss of part of the endometrial lining and blood (menstruation)

Proliferative – endometrial lining thickens and becomes vascular (primarily in response to oestrogen)

Secretory – endometrial lining becomes lush and moist from increased secretory activity (primarily in response to progesterone)

Pelvic Relaxation DisordersThe bladder, urethra, and rectum are

supported by the endopelvic fascia and perineal muscles

The muscular and fascial tissue loses tone and strength with aging

Benign Growths and Proliferative Conditions

EndometriosisPresence of functioning endometrial tissue

or implants outside the uterusResponds to hormone fluctuations of the

menstrual cyclePossible causes

Retrograde menstruation, spread through vascular or lymphatic systems, stimulation of multipotential epithelial cells on reproductive organs or genetic predisposition
