Ovulation: what is the temperature curve used for?: To visualize the progress of your menstrual cycle, locate your ovulation date and to know a little more about your fertility, there is a simple method: the temperature curve.
Temperature curve: a mine of information
The analysis of your temperature curve makes it possible to check if the ovulation has taken place, but that is not all. It is also used to detect your fertility period, to know quickly if you are pregnant or to identify particular problems when a pregnancy lags ahead. To make the most of it, doctors advise to take it every day on two cycles minimum. Start the first day of menstruation and repeat a chart for each new menstrual cycle. This may also be a natural method of contraception.
Temperature measurement: a thermometer, a graduated sheet and go!
Have a thermometer (Gallium or digital) and always use the same technique (buccal or rectal) to take your temperature throughout the cycle. It must be taken on awakening, at the same time every day and before any activity. However, do not panic, it is not to the minute. On the other hand, do not exceed an interval of half an hour more or less because the results may be distorted.
Once your temperature is up, write it on an individual sheet (your gynecologist can give it to you. Otherwise you can also find it on the Net) by placing the point in the appropriate box. Also, indicate the days you have sex. Mention your periods, Any abdominal pain or significant loss, but also any event likely to disrupt the cycle such as a cold, an infection, a bad night, a later awakening than usual, or the taking of medicines. Finally, connect the different points together.
A shift of a few degrees: ovulation in sight
The appearance of a standard curve shows two temperature trays separated by a small offset of a few tenths of a degree (0.3 to 0.5 ° C) which indicates, a posteriori, that ovulation has taken place. Each part of the curve is sawtooth. This is normal because of your temperature changes from one day to the next. From the first day of menstruation to ovulation (follicular phase), the body temperature remains around 36.5 ° C. This phase lasts on average 14 days, but can be shorter or longer if your cycles are less than or longer than 28 days.
Then the temperature rises and persists around 37 ° for 12 to 14 days (luteal phase). It is accepted that ovulation corresponds to the last low point of the curve before the thermal rise. This increase in temperature is due to a hormone, progesterone. It is secreted by the corpus luteum, resulting from the transformation of the follicle after ovulation. If there is no fertilization, the corpus luteum degenerates and the progesterone fall causes your temperature to return to normal, then the arrival of your period 14 days after ovulation. On the contrary, if an embryo develops, the corpus lysis persists, and your temperature is maintained for more than 16 days.
Regular cycles make it possible to spot the right time to make a baby. Spermatozoa have a life span in the female genital tract of up to 5 days for the heaviest. The egg, for its part, does not live more than 24 hours in the trunk. For it to work, you need to have relationships before ovulation but not after.
Your temperature curve is flat?
A flat curve means that there was no ovulation. Similarly, a short luteal phase (less than ten days) may suggest an insufficiency of progesterone secretion that impairs proper implantation of the embryo. However, do not worry, more thorough examinations and appropriate treatment usually help to correct these ovarian dysfunctions.
