If the chances of conceiving a healthy woman in her 20 years, about 50%, then 30 years old now, this coefficient decreased and women have only about 20% chance of conceiving.
Quantity and quality of eggs and sperm are the key components for successful conception. At birth, the girl has more than 1 million eggs.
This number decreased to about 250,000 to 300,000 when it reaches puberty. The woman will ovulate approximately 300 to 500 times during their reproductive years, which is more than enough. The body absorbs unused eggs - degenerative process called follicular atresia.
In this regard, men also have "internal clock." With age they are at risk of reduced reproductive capacity and the risk of defective sperm.
Several studies have found that age is not the only reason for existing reproductive problems.
Lifestyle, including smoking and alcohol consumption also influence the opportunities for conception.
Smoking before conception
There is growing evidence that smoking significantly prolongs the time of conception. Studies show that women who smoke cigarettes are subjected to risk of poor eggs and early menopause - both of which reduce the number of reproductive years.
According to a British Medical Association, the chances of conceiving fall by 40% in female smokers compared with nonsmokers. As a result, women take longer to conceive and the possibility of this happening naturally decreases. Furthermore, the risk of premature birth in women smokers is significantly higher. Smoking before and during pregnancy increases the risk of abortion, since it increases the likelihood that the egg has chromosomal abnormalities.
Health and lifestyle of the men also influences fertilnnostta and conception, according to research. Scientists at the University of Saarland found that men who smoke at least 20 cigarettes a day have lower concentrations of protamine, two proteins found in semen compared with men who do not smoke cigarettes. Protamine is considered an integral part of cell division, that ensure proper chromosome formation during conception.
Alcohol use before conception
Like how smoking affects fertility, alcohol drinking before attempted conception may also have an adverse effect, reducing the chances of successful pregnancy and increased risk of miscarriage.
A study published in the journal British Medical Journal found that women who drank more than 10 alcoholic drinks a week, have impaired fertility. Even those who consumed 5 or less per week had difficulties, compared with women who did not consume alcohol while trying to conceive.
It is believed that alcohol affects the levels of estrogen and other reproductive hormones in the body, leading to disturbances in ovulation - prolonged menstrual cycle and is the cause of anovulatory cycles. In the absence of ovulation, a woman's ovaries do not release the egg and therefore conception is impossible.
Alcohol consumption in men is associated with reduced sperm count and low speed, which means that a greater proportion of available sperm is unable to make a "long journey" to fertilize the egg of the woman.
For higher chance of pregnancy, health professionals recommend smoking cessation and alcohol at least 2-3 months before attempted conception.
In five pharmacies in Sofia everyone will be able to measure blood pressure, pulse and weight, and smoking - and the amount of harmful carbon monoxide accumulated in their lungs, using a special instrument Smoke check.
Measurements will be performed by a medical practitioner and are completely free.
Social service will be provided for front and visited other pharmacies in the capital and across the country.
Community projects include long-term social activities in small cities and is aimed at those most affected by the crisis groups in our society.
