The monthly fertility cycle of ovulating women (not menopausal) starts at the beginning of the first day of the menstruation period and ends on the first day of the following menstruation period. Ovulation usually occurs around the middle of the cycle (the twelfth to fourteenth days), but can occur at almost any time.

Guessing isn’t good enough. Because your body is unique, you cannot rely on "usual" or "average" predictions. OVULENS™ will enable you to learn when you are ovulating, and to make wise decisions about your own body.

In addition to letting you know when you are fertile, there is some slight statistical indication that the time of intercourse may, occasionally, have some effect on the sex of the baby. For example:

Female - Slightly more females are conceived when intercourse takes place three or four days before ovulation

Male - Slightly more males are conceived when intercourse takes place during ovulation , or no more than one to two days prior to ovulation.

By using the OVULENS™ daily for the first few months and keeping a careful record of your test results, you will learn the normal patterns for your own body. We have provided test logs for that purpose.

• Highly likely - From three days before ovulation to one day after ovulation
• Quite likely - Three to four days before ovulation
• Likely - Five days before ovulation, or one to two days after ovulation
• Not likely - More than five days before ovulation, or more than two days after ovulation

The average fertility cycle for ovulating women starts at the beginning of one menstrual period (day 1) continuing through mid-point ovulation (day 12-14) and ending at the start of the following menstrual period (day 28).

Ovulation is an egg moving from an ovary and into a fallopian tube. If the egg is not fertilized, after it has passed through the fallopian tube it is discarded by the body during the next menstrual period.

If an egg is fertilized by sperm, conception has occurred and the resulting embryo may, after passing on through the fallopian tube, attach to a wall of the uterus. When a fertilized egg successfully attaches to a wall of the uterus, a pregnancy has begun.

Sperm from the male are capable of fertilizing an egg starting from the time of ejaculation and continuing, with diminishing effectiveness, for up to five more days.

Eggs from the female can be fertilized starting from the time of ovulation and continuing, with diminishing effectiveness, for a period of one to two days only.

It is never certain when conception will occur at any given time in the fertility cycle. It is only less likely or more likely that conception may occur. The likelihood of conception depends on when sexual intercourse (with ejaculation) takes place, in relation to when ovulation takes place.
