How to do later on in life, ah, where doctors learned later, after she could no longer have children, are unknown ah, poor child to go on like this What Is,
Replies to her blessing, I hope she can do back to a happy girl.
general meaning of this story is that the sperm of rats on sanitary napkins, sanitary napkins resulted after the girl with the dirty pregnant. Now to analyze the analysis.
doubt 1: The survival time of sperm?
Even the girl's father to get sanitary napkins that moment, the mouse sperm was stained up, the article also mentioned the \I considered two days later adopted as a reference to human sperm, the sperm has very little chance to survive, let alone to the girl can enter the body. (Sperm survival time is not particularly fixed, will be the impact of various factors. For example humidity, temperature and intensity of sperm, 37 ℃ environment, motile sperm survival time is 4 to 8 hours.)
doubt 2: Female fertility in the menstrual period pregnant?
girl menstruation when used in sanitary napkins,
belstaff leather, menstrual periods can be pregnant? Unlikely minimal.
must first understand the structure of the female reproductive organs and their physiological functions in order to illustrate this problem. Within the reproductive organs of women by the ovaries, uterus, fallopian tubes form. The main function is to produce ovarian eggs and synthetic ovarian hormones, the uterus and fallopian tubes is the reproductive organs, containing hundreds of thousands of ovarian follicles, each follicle contains an egg. Follicle is basically no function until puberty. During adolescence, the role of the anterior pituitary gonadotropin, the gradual development of immature follicles,
belstaff uk, while synthetic estrogen. When mature follicles and ovulation, the egg Tang wall collapse,
belstaff outlet, cells become large and yellow, known as the corpus luteum, which not only produced but also the synthetic estrogen and progesterone. With the changes in ovarian, endometrial affected by cyclical changes have taken place in the corresponding. Estrogen to endometrial thickness, endometrial cells increased, increased, knowledge management becomes more tortuous, spiral, known as proliferative endometrium. After ovulation, estrogen and progesterone as the joint action of endometrial edema, and mucus glands produce large amounts of glycogen, increase in endometrial thickness from 1 mm to 6 mm,
belstaff online, known as the secretory endometrium. If the fertilized egg then discharged, and then the fertilized egg to the uterus by the fallopian tubes transport development, known as pregnancy, a chorionic gonadotropin synthesis of pregnancy tissue, which supports continued development of corpus luteum; If the egg is not fertilized, after ovulation 14 days, yellow atrophy, and stop secreting estrogen and progesterone, when blood vessels in the endometrium, endometrial necrosis and shedding, causing bleeding, formation of menstruation.
shows the time of menstruation after ovulation, the menstrual period is safe period, pregnancy may occur rarely.
doubt 3: mouse and human sperm to the egg?
OK, even if the mouse sperm is a monster, can keep for several days, dozens of days of activity, even if the girls get pregnant during menstruation, the mouse and human sperm to form a fertilized egg it? Such a thing can not happen because people are different species of mice.
1, humans and mice share genetic material with 80% and 99% of the genes. Genes and genes on the DNA chain between the \The number of genes of two species are about 30,000, most of them the same. However, there are hundreds of genes is a species unique to the hundreds of completely different genes, plays a decisive role. Mice have 20 pairs of chromosomes, 20 pairs of chromosomes in mice of about 2.5 billion base pairs, while human beings have 23 pairs of chromosomes, the 2.9 billion base pairs, so the mice with the human genome chromosomes could not pair.
2, mouse sperm through the zona pellucida can not. What is the zona pellucida? Outside of the egg with the outside, the ingredients are mainly sugar and protein, is secreted by the egg cell or other cells of the. In mammals, such as being called the zona pellucida, its role is to protect the egg, preventing sperm entering dissimilar. With the following number of eggs there is a layer of transparent secretory vesicles, called cortical granules, fertilization outside the exclusive way to release particles can cause cortical structural changes in the zona pellucida, the formation of fertilization membrane, to prevent other sperm to enter. Therefore, the zona pellucida is like a lock, only the corresponding keys to open the same, so that sperm and egg. Mouse sperm through the zona pellucida can not, how can we form a fertilized egg?
doubt 4, one pregnant with more than 20 people can tire?
healthy women 28-32 days to create a normal egg, left ovary was made round. It was also the first born will be made two or three or even more, some people will work together to build around, which is different eggs with students, will be born like twins or multiple births appearance. An egg can develop into a normal embryo, but also an egg and two sperm at the same time the formation of identical twins example. The article mentioned: \July 22, 1971, Italy gave birth to a 35-year-old woman 5 men and 10 women were 15 fetuses, which is a world record for most births, but because of fetal weight too light, all is not alive. If this girl can form more than 20 embryos, is definitely a new world record!
