Understanding about Ovulation

Understanding about Ovulation
Understanding about Ovulation - When ovulation is one of the most important thing for a woman to understand about her body, because it is a determining factor in getting pregnant or prevent pregnancy. The process can be a bit confusing, hopefully the text below can help you to understand.

Ovulation occurs when a mature egg is released from the ovaries, down into the fallopian tubes, and ready to be fertilized. Lining of the uterus has thickened to prepare for a fertilized egg. If no fertilization occurs, uterine lining and blood will be whole. Decay that has not been fertilized egg and uterine lining is called menstruation.

Ovulation facts about what you need to know:

• An egg lives 12-24 hours after leaving the ovary
• Usually only one egg is released each time of ovulation
• Ovulation can be affected by stress, illness or disruption of daily routines.
• Some women may experience some light blood spotting during ovulation
• Implantation/attachment of a fertilized egg usually occurs 6-12 days after ovulation
• Every woman is born with millions of eggs that mature to wait for the start of ovulation
• A menstrual period can occur even if ovulation does not occur
• Ovulation can occur even if menstruation does not occur
• Some women may feel a little pain or pain near the ovaries during ovulation called 'mittelschmerz', in German meaning "middle pain"
• If the egg is not fertilized, it split and absorbed into the lining of the uterus

Knowing When Ovulation:
A woman's monthly cycle is measured from the first day of her menstrual period until the first day of the next period. The average woman's monthly cycle normally is between 28-32 days, but some women may have shorter cycles or much longer.

Ovulation can be calculated from the first day of last menstrual period (HPHT) or by calculating 12-16 days from the next expected period. Most women ovulate anytime between day ke11 - 21 st day of their cycle, counting from the first day of last menstruation. This is what many people refer to as "fertile period"of the woman's cycle, because sexual intercourse during this period increases the possibility of pregnancy. Ovulation can occur at various times during the cycle, and may occur on different days each month.

Ovulation Cycle divided into two parts:
The first part of the ovulation cycle is called the follicular phase. This phase begins the first day of last menstrual period (HPHT) and continues until ovulation. This first half of the cycle, this can be very different for every woman that lasted approximately 7 days to 40 days.

The second part of this cycle is called luteal phase and lasts from ovulation until the next period begins. Luteal phase have a better time and usually only 12-16 days from ovulation. This shows that the day of ovulation will determine how long your cycle. It also means that outside factors like stress, illness, and the usual routine disruption, may cause the occurrence of ovulation which then effect changes in your menstrual period to come.

So the notion that stress can affect the menstrual cycle is only partially true. Stress can affect ovulation which ultimately determines when your period will come, but stress around the expected time period (luteal phase) will not make your cycle too late, because it was determined when it would come 12-16 days earlier!

From Menstruation to Ovulation (the details you may not know!)
When your menstrual cycle begins, your estrogen levels low. Your hypothalamus (which is responsible for maintaining your hormone levels) sends out a message to the pituitary gland which then sends the hormone FSH (follicle stimulating hormone). This FSH triggers some of your follicles to develop into mature eggs. One of these will develop into the dominant follicle, which will release a mature egg and the other will be destroyed. Once the follicles mature they send out another hormone, estrogen. High levels of estrogen will tell the hypothalamus and pituitary gland that there is a mature egg.

Luteinizing hormone (LH) is then released, referred to as the LH surge. Surge of LH causes the egg burst through the ovary wall within 24-36 hours and begin its journey down the fallopian tube for fertilization. Egg follicle is released is called the corpus luteum, and it will release progesterone that helps thicken and prepare the uterine lining for implantation. The corpus luteum will produce progesterone for about 12-16 days (the luteal phase of the cycle you are.) If the egg is fertilized, corpus luteum will continue to produce progesterone for the developing pregnancy until placenta takes over. You can begin looking for pregnancy symptoms as early as one week after conception. If no fertilization egg dissolves after 24 hours.

At this time your hormone levels will decrease and your uterine lining will begin to shed about 12-16 days from ovulation. This is menstruation (menstrual cycle) and bring us back to day 1 of your cycle. The journey then begins again.
