The Ogino Knaus method can be used to increase the chances of conception: let’s see how it works
The so-called natural contraceptive methods they are based on the calculation of the fertile days and on the observation of the changes that occur in the female body in the vicinity of ovulation. They are used to avoid unwanted pregnancy, but those trying to get pregnant also want to increase the chances of conception. There are essentially three natural methods: Ogino-Knaus method, Billings method is basal temperature measurement. Let’s see what the Ogino Knaus method.
Calculation Ogino knaus
The Ogino-Knaus method is based on the calculation of presumably fertile days starting from the average duration of the monthly cycle (therefore the time that passes from one menstruation to the other) to define which is the fertile window of the month. This technique was developed by the Austrian doctor Hermann Knaus, starting from the studies on female fertility that had been conducted by the Japanese Kyusaku Ogino.
To be able to calculate ovulation using the Ogino Knaus method, it must be assumed that menstruation occurs on average and in women with a regular cycle of 28-30 days, the 14th day after ovulation. Consequently, given that spermatozoa can survive a maximum of four / five days, it can be established what the fertile period is.
We do a example.
If the woman menstruated on May 1st, ovulation will probably occur on May 15th, to have her next period between May 28th and 30th. At this point, the fertile days in which the possibility of getting pregnant can be maximized are May 13-14-15-16-17.
Of course this method can be more useful for women who have regular cycles, although ovulation can be influenced by many external factors, from stress to drugs to nutrition.
The method can be used for both increase the chances of conception than to prevent a unwanted pregnancy even if several studies have put it trustworthiness in doubt is showed a high percentage of unwanted pregnancies. Like any natural method it is not a guarantee of protection, not even from sexually transmitted diseases, and can only be used in women who have an extremely regular cycle.
Ogino Knaus method online
On the Net there are several sites that provide a free online fertility calculator based on the Ogino-Knaus method. Generally it is enough to indicate the date of the last menstruation and the average duration of the cycle to have a graph showing the fertile window. Be careful because in order to use the Ogino-Knaus method effectively, it is essential for women to know the duration of their menstrual cycle with extreme precision.
In the days leading up to ovulation, the cervix, stimulated by estrogen, produces a mucus that helps the sperm to survive and navigate to the oocyte.
The Billings method is therefore based on the evidence that in the fertile period, generally towards the middle of the cycle, the cervical mucus has a typical appearance and a stringy consistency, similar to egg white. Of course, the effectiveness of this method depends on the woman’s degree of knowledge of her own body and the changes that occur coinciding with the arrival of ovulation.
Measuring basal temperature is another natural way to monitor fertility. How does it work? It is known that on fertile days the basal body temperature, that taken at rest in the early morning, increases by about half a degree. By measuring the temperature throughout the month and establishing, therefore, what your starting temperature is, you will be able to understand when you are about to ovulate and concentrate intercourse in those days.
Before understanding what are the possible fertile days of the month we must reiterate three fundamental points:
The woman ovulates at once during her cycle and an unfertilized egg can only survive for 12-24 hours;
spermatozoa only live from one to three days in the presence of fertile mucus, rarely up to five days;
menstruation occurs about 2 weeks after ovulation.
Given this, therefore, to calculate the fertile days you must first understand which is the average length of your monthly cycle, the one from one period to the next, and then calculate the central days to have a potential fertile window of five days maximum.
Generally, in women who have a regular cycle of 28 days, ovulation occurs around the 14th day, so the fertile period is from the 12th to the 16th day.
If you are planning a pregnancy and want to increase your chances of getting pregnant you should first start fill out a menstrual calendar to understand what the duration of the cycle is …
