Ovulation
(the release of one or more eggs from an ovary) occurs within
a 24 hour period and only once during a menstrual
cycle.
Day 1 of menstrual bleeding is the first day of the cycle.
The time
interval from day 1 to ovulation
may vary.
The time
interval from ovulation until menstruation is about
2 weeks.
Ovulation will occur early in a short cycle and later in
a long cycle.
Observing the cervical mucus
symptom gives information about being potentially
fertile or infertile on a day by day basis.
The fertility and infertility patterns ahead of ovulation
vary from woman to woman.
Once released from the ovary, the ovum (egg) lives for 12-24
hours, unless fertilised.
Sperm cells need suitable cervical
mucus to survive and reach the ovum in the Fallopian
tube.
Sperm cells may live for 3-5 days in suitable cervical mucus.
At infertile times they will survive in the vagina for only
an hour or two. |
