Question

Why happens when eggs are not fertilized?

Answer 1

The younger ones are born from females. The body of the female starts to prepare for this process from a younger age and this happens in the form of the menstrual cycle. This makes the body of the female strong and used enough to support and carry a baby for nine months in her womb.

Complete answer:
• The egg in the ovaries of the female uterus is the female gamete that fuses with the male sperm to form a zygote.
• The fertilization of the zygote takes place in the fallopian tube and then it is implanted in the uterus of the female.
• During the phase of ovulation, the egg every month waits for the sperm to come and fertilize and this happens during a phase namely ovulation.
• In a female human, ovulation occurs once a month.
• It is known to occur for around 6 days while the days vary from one female to another
• The ovulation time for the menstrual biological cycle is calculated to an estimate on the fourteenth day to be counted from the first day of the last period.
• The uterus is starting to prepare itself to receive the fertilized egg by growing thick, muscular, and rich in blood and tissues.
• When the egg is not fertilized, the thick uterus lining breaks down and the blood, tissues, and the unfertilized egg come out of the vagina commonly known as menstruation.
• When the egg is not fertilized the menstrual cycle takes place as the egg is shredded off from the body. When the ovary releases one egg every month at the same time, the uterus also prepares itself to receive a fertilized egg.
• The endometrium lining becomes thick and spongy for carrying the embryo and also nourishes the embryo if fertilization has taken place.
• The lining breaks If the egg is not fertilized and that results in the discharge of blood and mucous through the vagina.
• The menstrual cycle continues for around five to seven days until all the debris of the endometrium along with blood is discharged.

Note: There are chances that there can be fertilization of egg and sperm even when a female is undergoing her menstrual cycle. The chances are rough though.
The cold weather affects the cycle by increasing the pain level. Contraception methods are adopted to avoid unwanted pregnancies. There are chances that while intercourse STDs can flourish.
