What is ovulation?
The release of the mature egg from the ruptured follicle into the fallopian tube is called ovulation. It is a phase in your menstrual cycle in which one of the ovaries release an egg into the fallopian tube. Here in the fallopian tube, the egg awaits for some time to be fertilized by the sperm. Once the egg is released it can survive up to 24 hours before it is fertilized. If it is not fertilized it gets dissolved. In contrast, the sperms can stay alive for up to 5 days in your uterus, after intercourse, waiting for the egg to be released. Ovulation and fertility are directly related.
Ovulation occurs 12 to 16 days after the first day of your last menstrual cycle. Few days before as well as at the day of ovulation the cervical mucus becomes more slippery making it easier for the sperms to swim towards the egg. The length of the menstrual cycle and the day of ovulation are directly related. Because your period starts 14 days after you ovulate. The length of the cycle may vary from 21 to 42 days.
How Ovulation and Fertility are Related?
Ovulation and fertility are related to each other. Conception depends on the timing of intercourse. As described above, the egg once it is released from the ovary, is viable only up to 24 hours. In this short period of time, if the egg meets the sperm it gets fertilized and they both change into a zygote. The sperms can survive in the uterus of the female for up to 5 days. So, having intercourse few days prior to ovulation increases your chances of getting pregnant. Few days leading to ovulation and the day of ovulation are your most fertile days.
What is Fertile Window?
The ‘Fertile Window’ is the period of about 6 days in your menstrual cycle when it is possible to conceive from unprotected sex. It begins 5 days before ovulation until the day of ovulation. Suppose a 28-day cycle, ovulation occurs on day 14 so the Fertile window would be between day 9 to 15. However, the length of menstrual varies from woman to woman, where most of them do not have an exact 28-day cycle. So predicting your ovulation is crucial for determining your fertile window.
