The Miracle of Human Development in the Womb

“O people! If you are in doubt about being raised up (after death), then (contemplate your creation and evolution). We initiated your creation (i.e., chemical genesis) from (the extract of) clay,* then (your biological genesis) from a sperm drop (zygote), then from a hanging mass (clinging to the uterus like a leech—embryo) and then from a lump of flesh looking chewed, having manifest contours of elementary formation of some parts of the body and others yet to form (fetus), so that We might show you (Our power and the trueness of Our Revelations). So We cause whom We please to stay in the wombs till an appointed time. Then We bring you forth as an infant, then (nourish you) so that you may reach your youth. And of you are (also) some who die (early), and some are brought to the age of senility so that (he may see this state too that) having learnt so much knowledge, now he knows (just) nothing (once more). And you see the earth completely dry (i.e., dead) and, when We shower water on it, a stir of freshness and fertility runs through it. And it swells enriched, and puts forth in pairs every kind of blooming and beauteous vegetation. [* Comprising minerals, metals, salts and chemical elements like calcium, sodium, phosphorus, potassium, natrum, kalium, silicon, chlorine, iodine, fluorine, magnesium, zinc, sulfur, ferrum, cuprum, etc. These and other elements of clay also form the ingredients of a balanced diet essential for our nourishment. The animals whose meat and milk we take live on the vegetable world. The grain, vegetables, fruits and roots that form our food feed on the soil they grow in and absorb all its chemicals.]”
~ Holy Quran 22:5 (Dr Tahir-ul-Qadri)

An FX studio’s video production showing human development from a sperm to a baby. This video performs you the process of a fertilized egg to a baby in 3D!!

Excerpt from French documentary L’Odyssée de la Vie.


After sexual intercourse, sperm travels through cervix and uterus into the Fallopian tubes. Conception usually takes place in outer third of the Fallopian tube. A single sperm penetrates the egg and a joining of the genetic information occurs. The resulting single cell is called a zygote.

The zygote spends a few days traveling down the Fallopian tube, rapidly multiplying the number of cells through division. A mulberry-like mass, like a hollow rubber ball, 1/100 inch wide, results from cell division.
This ball of cells in the Fallopian tube is called a morula.

The embryonic stage begins on 15th day after conception and continues until about 8th week, or until embryo is 1.2 inches in length.

Week 3 we see the formation of the heart, the beginning development of the brain and spinal cord, and the beginning of the gastrointestinal tract.

Weeks 4 and 5 -1/4 inch long: Here we see the beginnings of the vertebra, lower jaw, larynx (“voice box”), and rudiments of the ear and eye. The heart, which is still outside body, now beats at a regular rhythm. Although arm and leg “buds” are visible with hand and foot “pads,” embryo still has a tail and cannot be distinguished from pig, rabbit, elephant, or chick embryo by an untrained eye.

Week 6 – 1/2 inch, 1/1000 of an ounce, we see the formation of the nose, jaw, palate, lung buds. Fingers and toes form, but may still be webbed. Tail is receding, and heart is almost fully developed.

Week 7 – 7/8 inch, 1/30 ounce (less than an aspirin), eyes move forward on the face, and eyelids and tongue begin to form. All essential organs have begun to form.

Week 8 -1 inch, 1/15 ounce: Embryo now resembles a human being. Facial features continue to develop and the external ear appears. We see the beginnings of external genitalia. By now, circulation through the umbilical cord is well developed. The long bones begin to form and muscles are able to contract.

At this point the embryo is developed enough to call a fetus. All organs and structures found in a full-term newborn are present.

Weeks 9 to 12 – 3 inches, 1 ounce: Head comprises nearly half of the fetus’ size and face is well formed. Eyelids close now and will not reopen until about the 28th week. Tooth buds for the baby teeth appear. Genitalia are now clearly male or female.

Weeks 13 to 16 – 6 inches: These weeks mark the beginning of the second trimester. Although the skin of the fetus is almost transparent, fine hair develops on the head called lanugo. Fetus makes active movements, including sucking, which leads to some swallowing of the amniotic fluid. A thin dark substance called meconium is made in the intestinal tract. Heart beats 120-150 beats per minute and brain waves detectable.

Weeks 17 to 20 – 8 inches: Eyebrows and lashes appear and nails appear on fingers and toes. This is an exciting time for the parents: The mother can feel the fetus moving (“quickening”) and fetal heartbeat can be heard with a stethoscope.

Weeks 21 to 24 – 11.2 inches, 1 lb. 10 oz.: All the eye components are developed, footprints and fingerprints are forming, and the entire body covered in cream-cheese-like vernix caseosa. The fetus now has a startle reflex.

Weeks 25 to 28 – 15 inches, 2 lbs. 11 oz.: Now we are entering the third trimester, we see rapid brain development. Nervous system is developed enough to control some body functions, and eyelids open and close. A baby born at this time may survive, but chances of complications and death are high.

Weeks 29 to 32 – 15 to 17 inches, 4 lbs. 6 oz.: These weeks see further development towards independent life, a rapid increase in the amount of body fat and the fetus begins storing its own iron, calcium, and phosphorus.

Bones are fully developed, but still soft and pliable. There are rhythmic breathing movements present, the fetal body temperature is partially self-controlled, and there is increased central nervous system control over body functions.

Weeks 33 to 36 – 16 to 19 inches, 5 lbs. 12 oz. to 6 lbs. 12 oz.: Lanugo (body hair) begins to disappear. A baby born at 36 weeks has a high chance of survival.

Weeks 37 to 40 – 19 to 21 inches 7 or 8 pounds: At 38 weeks, the fetus is considered full term.
