Ovulatory in a sentence

Cycle history Calendar-based systems determine both pre-ovulatory and post-ovulatory infertility based on cycle history.

Determination of pre-ovulatory infertility may be done by observing the absence of fertile cervical mucus; however, this results in a higher failure rate than that seen in the period of post-ovulatory infertility.

Fertility signs Most menstrual cycles have several days at the beginning that are infertile (pre-ovulatory infertility), a period of fertility, and then several days just before the next menstruation that are infertile (post-ovulatory infertility).

There are four phases of the menstrual cycle: Mentrual phase, Follicular (Proliferative) phase, Ovulatory phase and Luteal (Pregestational) phase.

A female’s first ovulatory cycle occurs when she is six years of age, and is followed by a two-year period of adolescent infertility.

Early treatment with ECPs containing only the progestin levonorgestrel has been show to impair the ovulatory process and luteal function. 83–87 p. 123: Combined emergency contraceptive pills.

Female orangutans experience their first ovulatory cycle around 5.8–11.1 years.

If a woman with previously regular cycles has a delayed ovulation due to one of these factors, she will still be fertile when the method tells her she is in the post-ovulatory infertile phase.

If she has an unusually early ovulation, calendar-based methods will indicate she is still in the pre-ovulatory infertile phase when she has actually become fertile.

Indeed, studies have shown that women's preferences vary across the ovulatory cycle.

Keeping a BBT chart enables accurate identification of menstruation, when pre-ovulatory calendar rules may be reliably applied.

Mucus- and temperature-based methods used to determine post-ovulatory infertility, when used to avoid conception, result in very low perfect-use pregnancy rates.

One system has the length of the pre-ovulatory infertile phase equal to a woman's earliest historical day of temperature rise minus seven days.

The first (or anovulatory) surge, could signal to males that the female is in oestrus by changing her scent, but ovulation does not occur until the second (or ovulatory) surge. citation Fertility rates in cows decline around 45–50 years of age.

This hypothesis allows researchers to examine whether women select mates who have characteristics that indicate high genetic quality during the high fertility phase of their ovulatory cycles.

This temperature shift may be used to determine the onset of post-ovulatory infertility.

To find the estimated start of the post-ovulatory infertile phase, ten (10) is subtracted from the length of the woman's longest cycle.
