Fertility is the natural ability to reproduce young one and to give life. In order to understand fertility basics we must learn about reproductive cycle. Female reproductive system is some how very complicated or complex and due to this system women trying to conceive and miraculously the pregnancy occurs. In order to learn about the system firstly we must know about the menstrual cycle.


Menstrual monthly cycle of every woman differs from one another. From puberty to menopause each women experience different cycles. Some have regular and other have irregular or even absent of cycle. But the general pattern of menstrual cycle is same in many cases.

  • DAY 1: At day first bleeding starts, some are facing heavy bleeding with severe pelvic pain while other experiencing no signs of pain. This bleeding last to minimum three days and maximum ten days.
  • DAY 7: At day seven normally hormones causes eggs in the woman ovaries to mature.
  • DAY 10-11: From day 10 to 11 the uterus lining starts thickens.
  • DAY 13-20: Ovulation time period starts and additional hormones commands the most mature egg to be released from either of the ovary.

This is the common pattern of monthly menstrual cycle which remain consistent among those woman whose cycle are regular.


There are almost three phases are associated with human reproductive system, these are outlined as;

  1. Ovulation.
  2. Fertilization.
  3. Implantation.


Every month when a woman whose cycle are regular begins her periods several eggs begin to grown in her both ovaries. Every egg grows inside the follicle. Ovulation starts almost at day 11 to 14 when body releasing the LH (luteinizing hormone) which can easily measured in urine about 15- 24 hours prior to release of an egg from the ovary. Ovulation can be readily measured through ovulation detection kits easily available in the markets or by online ovulation calculators, which can easily calculate your most fertile days in which you are able to conceive.

During ovulation follicle ruptures and release the egg inside it. The eggs than travels towards Fallopian tube and move slowly toward uterus or mother womb. If the egg meet the sperm present in Fallopian tube there is an option of fertilization of egg otherwise sperm dies.


Men sperms can survive in the woman cervical mucus for 3 to 5 days and once the sperm has gained entry to reached the egg it may be fertilized within 12 to 24 hours after egg released. Fertilization occurs when couples had unprotected sex before the egg was released. When one sperm fertilizes the egg they form a zygote. Zygote reaches the uterus after 3 to seven days of fertilization. The wall of the uterus starts to thicken to prepare the home for zygote and once egg implants in uterus it starts growing. Women comes to know when she had missed her periods and go for pregnancy test.


When embryo connect or attached to the mother womb wall this stage is commonly known as implantation. It is the first stage of pregnancy and from this stage embryo starts to grow and develop different types of cells and structure to become a healthy baby.

When woman comes to know that she is pregnant, a pregnancy test of her urine and some times in blood in order to confirm the pregnancy. Then she see the doctor for further advises about medicines and tests.
