Fertile Calculator

Before using a calculator or making calculations, a woman should know what her fetal or fertile period is when she becomes able to conceive a baby. Unfortunately, this is not possible on every day of the cycle, because a mature female reproductive cell is needed for fertilization. Conception is impossible without her. In theory, pregnancy can occur at any time during the menstrual cycle. However, the likelihood increases significantly in the days preceding ovulation, and immediately when the ripe egg leaves the ovary. We suggest that you independently calculate the most favorable days for conceiving a child using our calculator.

Female fertility, in simple terms, is the ability of a woman to conceive a child, that is, to give birth to offspring. The period when children can be born lasts from the beginning of the first menstrual period (menarche) to the last menstrual cycle (menopause) and is called reproductive or fertile age. Particular attention is paid to the fertility and ovulation window. These indicators largely determine a woman's ability to conceive and the period in which the probability of pregnancy is high. Many patients mistakenly believe that the fertility window in the menstrual cycle is 24-26 hours of ovulation. In fact, the sperm that have entered the female genital tract are able to remain active for several days. At the same time, the likelihood of fertilization increases during this period. It is called the fertility window. The real duration of such a window is 5-6 days.
