But want to delay pregnancy Shique unable to do so, so many elderly women are very upset. Infertility, and gradually became one of the topics here, elderly women. Then, leading cause of female infertility age and which of it?
1, old: decline in sperm quality
Studies have shown that 35-year-old female fertility irreversible decrease boundaries. Women over the age of 35 first child birth, pregnant or not on, or more than abortion or give birth to more children have problems such as deformities, dementia. But never to place the blame to the women. Pregnant women is difficult, and its partners also can not shirk its responsibility. New research shows that older if the husband's birth, his wife also cause miscarriage. Basically the age of 35 years as the boundary. Older, their sperm abnormal gene contained in the more inevitable decline in quality and wanted his wife pregnant is not easy. So, you want a child, was as early as possible!
2, pressure: the more pregnant pregnant not on the more they want
In addition to physiological reasons, there are psychological factors can not be ignored. From family and social and other pressures, will result in some women had to their own reproductive opportunities lost mother. Pregnant women also want to maintain a psychological balance, to avoid haste makes waste, anti-victim.
3, the weight loss: To build or to your baby
Excessive weight loss is difficult to pregnant women in almost all of the important reasons! However, rapid weight loss, especially by large doses of drugs, or abnormal weight loss diet, it is easy on the central nervous and endocrine adverse effects, causing estrogen, progesterone secretion decreased and the menstrual cycle and other disorders, menstrual symptoms reduced resulted in ovulation failure, the formation of infertility.
4, smoking, alcohol, bars: nightlife ruined sex life
Smoking, drinking, clubbing has always been the first choice for many women to relax decompression, but frequent or heavy drinking or alcohol will affect the individual's health. The prenatal and postnatal care is not only the enemy of smoking alcohol, and is one of the reasons causing infertility. According to the research found that women smokers may interfere with and disrupt normal ovarian function, causing irregular menstruation, premature menopause and infertility. Even pregnant women smoke, but also easy to cause miscarriage, premature birth and stillbirth, birth weight children is much lighter than non-smokers.
For men, because cigarette smoke contains a strong teratogenic substances, so men tend to make the sperm less smoking, smoking 20 cigarettes a day, only 50% of sperm viability, and the emergence of a variety of abnormal sperm, to bring about sterility or birth of children with congenital malformations troubles. And nicotine on sperm motility and penetration have an effect.
In fact, the career and family is not in conflict, the key is how to deal with you. Friends who want a baby, must be the best period in the reproductive growth, or regret can only be myself.
Older pregnant women to do the necessary checks
From the physiological perspective, the best women of childbearing age is 23 years old -29 years old, but now many women over 30 years of age see, age over 35 years as senior primipara primiparous. As the age increases, a corresponding increase in pregnancy complications, and are therefore areas of high-risk pregnancy, pre-pregnancy and pregnancy should strengthen the inspection.
More than 30-year-old woman in preparation for pregnancy, it is necessary to avoid exposure to harmful substances, such as newly renovated house, buy a new car, radioactive substances, starting 3 months before pregnancy folic acid tablets can be taken to prevent fetal neural tube defects, and to check whether the infection Toxoplasma gondii, rubella virus, cytomegalovirus and herpes simplex virus. If the acute phase of infection, it is best not pregnant at this time.
After 3 months of pregnancy can check blood chemistry tests such as blood, blood type and Rh blood group, urine routine, liver function, kidney function, hepatitis B and C testing, HIV, syphilis, electrocardiogram.
After regularly prenatal care, pregnancy 16-36 weeks once every 4 weeks, 36 weeks later checked once a week. Each inspection must be measured body weight, blood pressure, check for edema, review the fetal position, listening to fetal heart rate, if necessary, to conduct B-ultrasound and fetal heart rate monitoring.
Pregnant women with increasing age, increased rate of fetal chromosomal aberrations, the birth rate in children with Down syndrome also increased with age. 30-year-old pregnant woman, the birth rate of Down syndrome 0.3%, more than 35 years of age to 0.6 percent, over a 40-year-old up to 1.6%, so for the elderly primipara required for prenatal diagnosis ( also known as intrauterine diagnosis, prenatal diagnosis), analysis of risk of Down syndrome risk derived.
