Pregnancy begins when a sperm fertilizes an egg during a woman's ovulation, the phase when a mature egg is released from the ovary and travels down the fallopian tube. If sperm is present, fertilization occurs, forming a zygote, which then moves to the uterus. Within about 6-10 days, the zygote becomes a blastocyst and implants itself into the uterine lining, leading to pregnancy. Hormones, particularly hCG, are produced to maintain the pregnancy, allowing the embryo to develop into a fetus over

Pregnancy kaise rukti hai ? Ovulation days may differ in case of irregular cycles . Fertilisation occurs when a sperm cell successfully meets and fuses with an egg cell, forming a zygote.

It all begins with a single sperm and a single egg — but within 40 weeks, that tiny union becomes a fully formed baby. Here’s how the miracle unfolds: 1. Fertilization During conception, one sperm successfully enters the egg. Their genetic material combines instantly, forming a zygote — the first cell of a new life. 2. Early Cell Division Within hours, the zygote begins dividing rapidly as it travels down the fallopian tube. By day 5, it becomes a blastocyst, a tiny cluster of hundreds of cells.
