Swedish photographer Lennart Nilsson spent 12 years of his life taking pictures of the foetus developing in the womb. These incredible photographs were taken with conventional cameras with macro lenses, an endoscope and scanning electron microscope. His first photo of the human foetus was taken in 1965. Nilsson got his most precise shots with the help of a cystoscope a medical instrument which is used to examine the inside of the urinary bladder. He attached a camera together with a tiny light to it, and took thousands of photos recording the life of the embryo in its mother’s womb.

3. The moment when sperm meets egg is known as conception.
4. Of the 200 to 300 million spermatozoa, only one of these fertilizes the egg.
5. The head of the spermatozoon is filled with the genetic material.
6. The embryo moves towards the womb down the fallopian tube.
7. The embryo gets attached to the wall of the uterus after a week.
8. After 22 days, the grey portion is the brain of the child.
9. The heart of the foetus begins to beat by 18th day of development.
10. The foetus begins to grow by 28th day of development.
11. By five weeks, the foetus grows by 5mm and we can see the openings for mouth, nostrils and eyes.
12. after 40 days of development, the exterior cells of the foetus gets joined with the smooth surface of the uterus wall forming placenta.
