Age of future parents
From a medical point of view, favorable forconception of the child is 20-30 years old. Children born to such married couples are less likely to suffer from congenital diseases. The human body in these years in most cases fully formed, the hormonal background stabilized, chronic diseases are unlikely. The tissues and muscles of the female body still have sufficient elasticity, which becomes a favorable sign for the normal course of pregnancy and mild labor. However, in recent years, an increasing number of women have given birth to children after 30 years, and even after 35. A modern woman seeks to achieve career success and stabilize her financial situation before she has children, and often ignores this favorable period when there are almost no problems in conception . This late period does not at all serve as a harbinger of deviations in the state of health of both the woman herself and her future child, but the likelihood of these troubles is high compared to younger women. For example, one of the reasons for the development of Down's disease in children in the womb is the "risky" age of the parents: for women under the age of 18 and over 35 and men over 45. Genetic abnormalities the child receives in most cases in connection with this factor. Pregnancy often occurs in these cases with complications.
Efficacy of spermatozoa on different days
As for the male body, hisphysiology is such that seminal fluid in a healthy man is produced regularly, regardless of the date, days of the week or other time frame. However, when planning conception, it is worth considering that it is not necessary to perform sexual acts too often, otherwise the spermatozoa will not have time to "gain strength", will be inactive and immature. Specialists say that the most optimal intervals for ejaculation for successful conception are 3-4 days. Accordingly, abstinence in the process of fertilization of the egg will benefit. In this case it is worth considering that high-quality spermatozoa keep their functions, having got into the body of a woman, for several days. Future parents can independently calculate the period of ovulation and plan sexual acts, taking into account these indicators of the "strength" of the male seed. Also, some experts say that the psychological state of a man also plays a role in the possibility of conception. Stresses, fatigue, neuroses along with various chronic and acute diseases of the body can lead to the lack of ejaculation and affect the quality of seminal fluid. 
Definition of ovulation
What is ovulation and what happens in the femaleorganism in this period? Ovulation in gynecology means the middle of the menstrual cycle - the date of maturation of the egg when it is ready for fertilization. It is during the days of this stage of the cycle that you should have sexual intercourse for the purpose of conception of the child in order to make this process as effective as possible. Calculate the days of ovulation with a stable menstrual cycle is very simple. The most accurate conclusions can be drawn by analyzing 2-3 cycles of menstruation. The standard way of determining the day "X" is as follows. It is necessary to count one week from the first day of the month, add a few more days and get about the middle of the cycle. The next 7-10 days after this date are considered the most favorable for conception. Another option is to determine the middle of the cycle on the basis of a special calendar that is observations of past cycles. Approximate ovulation corresponds to this day. Then you need to determine the limits of possible ovulation - the chosen day should be the middle of a weekly time interval. Now it is enough to calculate the number of days from the beginning of the monthly until this week. Based on the date of the onset of the next menstruation, you can draw the appropriate conclusions about the time of onset of another ovulation, using the calendar. Calculate this date will help and interactive calendars on thematic Internet portals, where you need to specify the first and last days of the previous cycle and get acquainted with the date of the nearest ovulation. With an unstable menstrual cycle or non-occurrence of pregnancy, despite timely sexual intercourse during the period of calculated ovulation, doctors recommend using the method of basal temperature measurement. It is necessary to rectally measure the body temperature every day and record the parameters of the schedule to determine the favorable days for conception of the child. Approximately to the middle of the cycle, the basal body temperature rises by several degrees, which is a signal about the onset of ovulation. And the date of ovulation itself is usually marked by a drop in temperature, and the next period after this event is an increase. In the chart, this will be evident. What other methods can be used to determine ovulation? There are other methods for determining favorable days without calendars, which every woman can notice at home. Natural vaginal discharge becomes more abundant and less viscous. Ovulation days are characterized by signs similar to the onset of menstruation: painful sensations in the chest, increased fatness of the skin and others. However, this method refers to the subjective and is the most inaccurate, unlike the calendar, for example.
Causes of ovulation
It happens that ovulation does not occur. Despite systematic sexual acts on "good" days and careful observance of the child's conception calendar, nothing happens. What are the reasons for this? Most often, the reason for this are violations in the hypothalamic-pituitary-ovarian system. Provoke dysfunction can stress, chronic diseases of the reproductive system, infections and other factors. Problems with the health of the thyroid gland, adrenal glands, inflammatory processes in the genitals are the main causes of abnormalities. In case the conception does not occur during several periods of a month, and the menstrual cycle is unstable, it is necessary to consult a gynecologist. Having found out the reasons for the absence of ovulation, doctors will prescribe adequate treatment, possibly with the use of hormonal drugs. Proper treatment will get rid of existing problems and conceive a child on "good" days.
