Ovulation Cycles

The development of a human being is a traumatic or pleasurable journey, depending on the reception a female egg receives on its journey from ovary to uterus via the fallopian tube. The menstrual cycle is a minor hurdle, as the duration of the menstrual cycle has to be considered for this excursion. The hardships can differ from eight or nine days to more than 21 days, and is successful when cervical mucus turns sticky, white, milky or cloudy. This is a signal for ovulation.

The Ovulation Cycle begins with the secretion of two hormones by the pituitary gland situated in the brain. Production of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) is controlled by an area of brain called the hypothalamus. This hypothalamus works like a computer, analyzing nervous signals from areas of the brain affected by emotions and environmental factors, such as stress and nutrition. It analyzes hormonal signals, oestradiol and progesterone, generated by ovaries and other endocrine glands and transmitted into blood stream. The sum total of these activities determines the quality of the ovarian activity.

It is a well-set machine, sending signals to the ovaries to prepare release of eggs ensconced in individual follicles. The dominant egg forges ahead to the next phase, and ovulation occurs about 12 to 24 hours after LH surge. The follicle then forms into a cyst, corpus luteum, responsible for producing progesterone to nurture a fertilized egg. This stage signals PMS symptoms such as breast soreness, moodiness and water retention. The final stage is when this fertilized egg embeds itself in the uterine wall and produces human Chorionic Gonadotropin (hCG). The presence of this hormone is instrumental in alerting the ovary to continue with its function. If somehow the ovary does not receive the signal it stops generating progesterone 9 to 11 days after ovulation, causing shedding of uterine lining, or menstruation, and is the start of another Ovulation Cycle.

The crucial difference in individual Ovulation Cycles is how women accept this most fertile period of the cycle. The egg can live for about 20 hours after ovulation, and if 2 eggs get matured the second is released within 24 hours of the first. It is a possibility that an Ovulation Cycle can occur without ovulating. It generally occurs in girls who have just started menstruating, breastfeeding women, or those going through menopause, or in women whose cycles extend to more than 35 days.

There is a flip side to every pleasure. The Ovulation Cycle can be a cause of ovarian cancer, due to its demand of rebuilding of tissues and new cells through synthesis of DNA.
