The birth of a life is when to begin? Let us look at a simple flow chart that the process of new birth.
Parent hypothalamus - pituitary - testicular axis, reproductive Endocrine System control several spermatocyte mitosis, proliferation, renewal, differentiation two primary spermatocytes mature secondary spermatocyte division differentiation of the sperm cell Golgi, cap on, set body of, mature sperm (from spermatogonia to sperm formation takes about 70 days) emissions sperm maturation and storage of sperm (about 3 weeks) father's sperm and mother's egg implanted zygote embryo embryo newborn baby.
From the above flow chart can be more intuitive that learning consists of four stages of human development, the formation of germ cells within one germplasm continue. Fully reflect the father's close relationship with eugenics. Second, fertilization, implantation of the embryo formation stage. Third, human development, the late stage. Fourth, the perinatal stage.
Father of human development in the first stage in the course of normal development of sperm, at any time by various factors, many of the small exception, small deformities, from quality to quantity, from the surrounding abnormal sperm change to small changes in the sperm itself may lead to the failure of eugenics, there infertility, birth defects, and even abortion, stillbirth, premature birth, stillbirth and a variety of different types, different types of congenital anomalies or congenital malformations. To develop into normal embryos, sperm must first enable the egg with the conditions of normal pregnancy, maturation and sperm must be able to; in normal Physiological Cases, the sperm must be developed normally; must have sufficient number; Therefore, to eugenics the same father and mother to shoulder the heavy responsibility.
Studies have shown that birth defects, Genetic Factors accounted for 25% of which comes from physical, chemical and biological factors of 10% of disabled children's father had a 21.59% exposure in the work environment-ray, microwave, heat, heavy metals, chemicals, Pesticide And so on. The mothers accounted for 17.85%. Fathers of disabled children suffering from flu, fever, rubella, Toxoplasma gondii infection, cytomegalovirus infection, herpes, allergies, mumps, hepatitis and other diseases accounted for 5.3% of mothers suffer from the disease, accounting for 24.89 percent, the father of disabled children smoking and alcohol accounted for 55.91%, while only 2.2% of mothers. father alcohol addiction occurs with disabled children have a very significant relationship, and there was no significant relationship between mothers.
I have encountered in the clinic a couple of three consecutive child born disabled children. First child is not brain child, second child is a congenital developmental defects of the lung. The third child is a congenital Heart disease . Arrhythmia. Mothers without the disease, and no family history of genetic diseases, chromosome abnormalities was found, his father and no family history of genetic diseases, chromosomal abnormalities are not, however, his father Paint Factory more than 5 years, does not exclude the father of chemical factors leading to the party due to sperm quality. I also see the alcoholic father of mental retardation in children. I am an expert from China Crafts Suppliers, usually analyzes all kind of industries situation, such as phuket villas , palm jebel ali.
