Summary of En el vientre materno II: Gemelos, trillizos, cuatrillizos HD [Documental completo]

00:00:00 - 00:45:00

This documentary follows the progress of several pregnant women who are expecting multiple births. The documentary highlights the medical challenges of having multiple births, and the importance of the babies' lungs having fully developed by the time they are born. The documentary also follows the birth of each of the babies, and shows that each baby is identical and breathing and crying immediately after being born. A few weeks later, the twins are born, and they are immediately weighed and measured. The documentary concludes with the expected birth of the third baby, and shows that everything went as planned.

• 00:00:00 This documentary follows three different pregnancies, each resulting in unique triplet births. The documentary follows the development of the three babies and their unique relationships with one another.
• 00:05:00 The video describes the development of a human embryo from the first day to the eighth day after conception. It covers the process of fertilization, the splitting of the embryo into two, and the formation of the placenta. It also talks about the rarity of identical twin births and the reasons behind them.
• 00:10:00 This woman, Julie, is very atypical. Although she doesn't know it, her fertilized egg has split into four. This is probably one of the few pregnancies in the world that carries quadruplets. These tiny fetuses have each their own individual union, but share the same umbilical cord. As a result, during 30 weeks they'll each receive the same amount of oxygen and food from their mother. biologically, they are some of the closest humans can conceive. Rachel or another mother will go through a completely different process. She has released two eggs, one from each fertilized ovary, resulting in quadruplets, or "bio-vols." These are said to be genetically different from identical twins, who share half of their genetic material. On the seventh day, all of our eggs are implanted in the mother's womb. In the next few days, the blastocito (a small, early form of the human embryo) begins to enter the womb via the uterine wall. At this point, the uterine lining is swollen with hormones. These tiny army of cells invade the uterus and, little by little, the members of their team separate to form the primary cords between the mother and the placenta. As changes happen
• 00:15:00 This video documents the development of twins, triplets, and quadruplets. The first few cells in a developing embryo begin to pump blood, and later, when the brain has developed, the rhythm of contractions is increased or slowed, depending on the needs of the body. Throughout life, a heart will beat 3 million times. This woman, 32 years old, conceived a year ago and created an egg that was then fertilized. Two embryos were divided and formed identical twins, but the story does not end there. Another embryo was fertilized from the twins' sperm and joined a third brother. This process is called super-fecundation and is quite rare, occurring in only about one in 400 pregnancies. In Jennifer's case, the second embryo was fertilized by the survivor of the first penetration, but this is not always the case. Technically, every egg could have been fertilized by the sperm of 12 different men. In some cases, a woman takes fertility medications to increase ovulation, and some of these eggs are fertilized through the sex act. In other cases, fertilized eggs are transferred to the woman's uterus in a dish of Petri dishes and then implanted into her womb from the beginning of fertility treatments in the 1970s.
• 00:20:00 The video discusses the development of fetuses during the first trimester, focusing on the growth of their structures. It notes that one-third of the fetal size is constituted by these structures, and that the fetus begins to resemble a small human at this point, being known as a fetus from the Latin word "cría." In the ninth week of pregnancy, the brain begins to develop rapidly. Every minute creates on average 2 million cells and half a million neurons, which equals 100 million million in total at birth. At this stage, the body begins to move. These involuntary spasms play a vital role in stimulating the growth of muscles and the strengthening of bones. The heart acquires greater speed as it begins to beat at a rate of 75 per minute in the third week of pregnancy. Gradually, the pace increases and by the ninth week it is beating at a frenetic 165 per minute. During the second half of pregnancy, the rhythm gradually slows down until it reaches between 125 and 150 per minute. The heart of a child beats at a median rate of between 70 and 100 times per minute, while that of an adult beats between 70 and 80 times per minute. In the tenth week of pregnancy, pregnant women undergo their first ultrasound. These images are produced by
• 00:25:00 The documentary discusses the unique behaviors of fetuses during early development, specifically how the fetuses of multiple births are often observed playing together. By the 20th week of pregnancy, the fetuses have grown to be around 14 cm (5 in) in size and can fit in the palm of their mother's hand. At this point, the fetuses are still not able to open their eyes, but the eye structure has begun to form. The number of nerve cells in the fetuses' brains is increasing rapidly, and a baby at this stage typically weighs two and a half kilograms (5.5 pounds). The fetuses of multiple births also tend to be premature, and as a result, doctors prescribe mothers a hormone to help form surfactants, which helps the lungs separate during respiration. However, due to the premature nature of most multiples, the doctors also prescribe mothers a hormone to help form surfactants. For the first time, the mothers will be able to see their multiples interacting. However, onscreen, only one fetus will be shown at a time. By the fourth month of development, the fetuses have grown to be about 16 cm (6 in) in size and have reached their maximum weight potential. At 24 weeks into development
• 00:30:00 In the prenatal stage, twins, triplets, and quadruplets exhibit similar behavior to full-term babies. However, únicos (unlike multiples) have a more limited vision in the dark. Some researchers believe that at birth, babies can see in the dark. However, únicos have fully formed ears and can hear the heartbeats of their mothers and the sounds of amniotic fluid. Also, they can sense sounds from the outside world and even music and voices. By 28 weeks, babies have reached the eighth week of prenatal development. At this point, doctors pay attention to one of the most important aspects of newborn life - the umbilical cord. This masterpiece of nature is made of tough and resilient material and contains two arteries and a vein that are tightly intertwined so it does not knot. Even if the cord wraps around the baby's neck, it can provide the baby with vital nutrients. However, for twins who share the same amniotic sac, this line of protection also constitutes a great danger. The twins can get trapped in each other's cords and interrupt the baby's blood flow and oxygen supply. This ultrasound shows a tangled cord and one of the reasons why twins who share the same sac
• 00:35:00 This documentary follows the progress of 32 pregnant women who are expecting triplets or more. The documentary highlights the medical challenges of having multiple births, and the importance of the babies' lungs having fully developed by the time they are born. The documentary also follows the birth of each of the triplets, and shows that each baby is identical and breathing and crying immediately after being born. A few weeks later, the twins are born, and they are immediately weighed and measured. They are then transferred to separate incubators to keep them warm and healthy. The documentary concludes with the expected birth of the third baby, and shows that everything went as planned.
• 00:40:00 This documentary follows the birth of quadruplets, as seen through the perspectives of the mother, father, and two sets of twins. The first set of twins, a boy and a girl, are born shortly after nine months' gestation, and the team of doctors and nurses working on their behalf are immediately concerned about their health and well-being. The second set of twins, a boy and a girl, are born a few minutes later, and the team is relieved to find that both babies are healthy. However, the team is still concerned about the possibility of one of the babies succumbing to prematurity. In the third set of twins, a boy and a girl, the baby boys are born first and, as is usually the case with twins, the cord connecting them is tightly wrapped around their necks. The mother promptly yanks the cords, freeing the babies and causing the father to exclaim in surprise and excitement. The documentary then switches to the perspective of the mother as she laboriously pushes each of the quadruplets out into the world. It is a moment of intense joy and relief for her as she watches each of her babies take their first breaths. The team of doctors and nurses then begins to operate on the babies, and soon the third and fourth babies
• 00:45:00 Rachel's twins were born 8 weeks premature, but have been living together for nearly a year now. Each baby has their own personality, but are very similar due to their genetics and time spent in the womb. Although identical twins are much more alike, identical triplets are even more similar due to their shared womb environment. Jennifer's triplets were born 3 months premature, and are growing very quickly despite only weighing 1 kilogram at birth. Jennifer and Jose feed them with a special milk that contains extra calories to help them grow quickly. They took 4 weeks to reach their average weight, and today weigh 3 kilograms. Even with all the advances in medicine, multiples births are still a miracle reproductive event, but are a small percentage of all human births. We are all fascinated by multiples, for the science it is more than just a challenge; it is also a window into the astounding world of the womb, and provides knowledge about the surprising behavior of human beings. Multiples are a source of inspiration and comfort for our twins and triplets as they grow and develop throughout their lives.
