The processes and functions that are responsible for the creation of a new life border on a miracle of nature; they are the result of a perfect interplay between the male and female body. If you and your partner desire to have a child, you will be increasingly confronted with the subjects of reproduction and fertility.

A child is conceived when a male sperm cell fertilizes a female egg cell. For this to occur, an intricate series of biological processes is required.

Falling pregnant is an extremely delicate process, which is why a prompt conception can never be taken for granted. You should not be discouraged if you have not fallen pregnant within a few months – a waiting period of one year is not uncommon.

Medical specialists refer to an unfulfilled to desire to have children, or sterility, in cases where couples have engaged in unprotected intercourse for a period of one year without resulting in pregnancy. For more information on this subject, please read the page entitled Unfulfilled Desire for Children.

Determining the fertile period

There are several different methods of determining this fertile period with varying degrees of accuracy:

Our ovulation calculator allows you to calculate your approximate fertile period with the help of personal information (length of cycle and first day of your last menstruation). The result is, of course, based on average values and in no way guarantees pregnancy.

One to two days following ovulation, the temperature of a woman’s body generally increases by several tenths of a degree Celsius. Measure your body temperature once a day, always at the same time (the ideal time is in the morning before you get up!) and record the results in the fertility table, a special curve sheet, which you can download at the end of this site. Based on your body’s temperature curve, you can calculate the probable date of your next ovulation.

This basalt temperature method can, in addition, be supported by the use of a cycle computer, which is also often used for contraception. Some cycle computers can also determine the time of ovulation based on the hormone levels in your urine.

The consistency of the cervical mucus changes several times over the course of a cycle. Following menstruation, the glands produce little or no mucus, then viscous mucus, and shortly before ovulation clear, fluid mucus that facilitates the conveyance of sperm via the cervix to the egg cell.

Keeping simultaneous records of body temperature and the consistency of the cervical mucus increases the reliability of your calculations.
