According to studies, about one-third of women aged between 35 and 39 years and over half of women over 40 years of fertility and age. Many women do not realize this fact until they face difficulty conceiving due to age.
If a woman over 35 years has not achieved pregnancy after trying to conceive for six months, it is recommended that you consult your doctor. The reason why is expected only six months compared with the year expected to be recommended for women under 35, simply based on being able to recognize any potential obstacles that prevent conception and should be corrected as soon possible.
The social changes of recent decades, as the increasingly active participation of women in the workplace and the assessment of their professional achievement and economic independence, have helped to increase the percentage of late marriages, about 30 years, which has delayed the age of the mother in search of their first pregnancy.
For this reason, now there are many women who decide to become mothers after 35 years. In fact, today one in five women has her first child after this age. Fortunately, most have healthy pregnancies and healthy babies.
Technical advances in reproductive medicine and constant dissemination in the media have contributed to the misconception that getting pregnant is something simple and that there is a quick and effective way to overcome any problems that prevent pregnancy treatment and the age of the mother is in no way an obstacle to having children.
Usually, women begin to experience a decrease in fertility after 30 years. Often a woman over 35 years will take longer to get pregnant than a younger woman. Men may also experience a decrease in fertility when approaching 40 years.
According to studies by Professor Donald Evenson, University of Dakota, age is an important factor influencing the reproductive capacity of both women and men. He concluded that with age increase sperm chromosomal failures: DNA that carries the sperm samples in his head more anomalies older the man, and as a result, the ability to fertilize the egg it descends.
Statistics indicate that under normal conditions, between 18 and about 30 years, the rate of human fertility is 25%, that is, of every 100 couples who have sexual relations without preventive measures during their fertile period, 25 of them achieved become pregnant during the first month of trying. After a year in a normal population, most of the roughly 80 couples each 100- should get pregnant. However, studies indicate that between 30 and 36 years, on average, fertility decreases by 20%, while between 36 and 40 years reduced fertility increases to 40%.

Causes Of Fertility Decline With Age
Another factor infertility associated with older women constitutes the aftermath and the presence of pelvic inflammatory diseases, provoked or- infections and sexually transmitted diseases, which can cause severe damage to the female reproductive system. In older women, this risk factor would be increased when considering a longer period of active sexual life, and presumably a greater number of sexual partners.
It is also a premature ovarian failure, which occurs when a woman experiences a decline in ovarian function and menstruation in early age, ie 40 years before a determinant of infertility. Among the causes of this condition are the chemotherapy, ovarian surgery, diseases such as lupus, insulin-dependent diabetes and hypothyroidism, among others.
Does The Risk Of Spontaneous Abortion Increases With The Age Of The Woman?
Most spontaneous abortions occur during the first trimester of pregnancy in women of any age. The risk increases with the age of the woman. Studies suggest that about 10 per cent of recognized pregnancies in women aged between 20 and 30 years of age ends in spontaneous abortion. This figure increases to approximately 20 per cent in the case of women between 35 and 39 years old, about 35 per cent to 40 and 41 years old and more than 50 per cent by age 45. The increased risk of spontaneous abortion associated with age is due, at least in part, to the increased incidence of chromosomal abnormalities. See chapter Spontaneous Abortion.
What Is The Most Fertile Age In A Woman?
Every time women decide to have children later. The labour market participation of women and the difficulty in achieving emotional stability both as a professional have caused delay motherhood for more years than desired. As mothers at an older age, the biological clock takes its toll; fertility drops and is necessary to resort increasingly to the methods of assisted fertilization.
Biologically speaking, the most fertile period of a woman is between 16 and 28 years old; when sexual maturity and both physical and psychic energy is achieved are at an optimum level. In this age diseases that interfere with fertility, they are practically nonexistent.
So, at age 20, the chances that a woman to get pregnant in the days fertile reach 25 percent, when you reach age 30, this percentage is reduced, usually 15% and after 35 the chances of pregnancy remain at 10%. Finally, at 40, this figure drops to 5 percent.
