Fertilization is the process of the fusion of the sperm and ovum which help to start another life. Sperm is the male gamete and ovum is the female gamete. Fertilization begins when the sperm comes in contact with an oocyte. The zygote (the new cell that is formed after fertilization) divides into two, then into 4, 8, 16 cells and so on and finally forms the baby that has more than a trillion cells in just 38 weeks.
How does fertilization take place?
In each ovulatory cycle a mature ovum is released from the ovary normally every 14 days. The female hormones estrogen and progesterone under the influence of FSH and LH control the growth and maturation of ovum. Each menstrual cycle has a pre-ovulatory phase, ovulatory phase and menstrual phase.
When is fertilization and pregnancy most likely to occur?
Fertilization of the ovum is likely if you have intercourse around the time of ovulation. This period is called the 'fertile phase' of the cycle. Ovulation generally takes place l4 days before the onset of a period and in a 28 day cycle it takes place on the 14th day. In people with a regular cycle the probable day of ovulation can be predicted but if you have irregular cycle the period when ovulation will occur cannot be predicted.
