Fertile period in the menstrual cycle
How long is the fertile period
Couples who have been planning pregnancy for a long time know what a fertile period is. It is no secret that not everybody can get pregnant immediately after the abolition of contraception. There are such families where the waiting period of pregnancy is stretched for many years. It is then that the woman starts counting to determine the so-called "favorable" days, that is, to calculate the fertile period. In other words, the phase (or period) of fertility is the time of ovulation, when a ripe egg leaves the follicle. Moving through the fallopian tubes, the mature egg is ready for fertilization. At this point, fertilization can occur, provided that the semen enters the woman's body. An egg cell lives on average 24-48 hours. And the viability of sperm is from 3 to 6 days, depending on the state of health of the man. Consequently, the fertile period increases from 2 to 5-6 days.
How not to get pregnant using the method of calculating the fertile period?
Before you start counting, you need to understand that with the help of this method can not count on absolute protection from unwanted pregnancy. If a woman has an active sex life, then protected sex during fertility can lead to pregnancy if the couple does not use contraceptives on all other days. Rather, this method helps to determine the favorable time for conception, so as not to miss the right moment.
How to determine your own fertile period?
Most women know how long her menstrual cycle lasts on average. It is usually 28 days, but deviations up and down are possible. It is known that ovulation occurs approximately in the middle of the cycle. Therefore, with a cycle of 28 days, ovulation can be expected at 13-14 days. As mentioned above, we add to this interval three days before ovulation and after ovulation.It turns out that the highest probability of getting pregnant is from 10th to 17th day of the cycle. But it must be remembered that ovulation does not occur in every cycle. It is rather difficult to calculate and determine ovulation by any signs on your own or with the help of tests. In both cases, the result will be inaccurate.The most informative and accurate method is the determination of the fertile phase using ultrasound. Seeing a ripe nelopnuvshy follicle size 22-24 mm, we can conclude that ovulation will occur in the next day. And the chance to get pregnant these days increases significantly.
The frequency of sexual intercourse in the fertile period
More recently, doctors recommended not having sex more often than after 2 days, and all this to improve the quality of sperm. However, modern research refutes this claim. If the goal of the couple is pregnancy, then you need to have sex every other day in the fertile period. It has been proven that with more frequent ejaculations, sperm motility increases, and this is the main factor affecting sperm quality. But excessively frequent sexual intercourse can lead to a decrease in the percentage of "mature" sperm.
