Ovulation
Cycles
By Elizabeth Morgan
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.
Ovulation provides detailed
information about ovulation, ovulation after miscarriage, ovulation
and conception, ovulation bleeding and more. Ovulation is the sister
site of PMS Symptoms.
