Age and concept - clock

Age and concept - clock

For many couples, ticking biological clock is not always harmonize with those plans and preparations still want to become parents, but do not ever find the right time.

What is the clock?
Clock is primarily a domestic mecansim Periodicity carrying the body that controls many functions and internal activities such as metabolic changes, cycles of rest (cicardian cycle - a cycle of 24 hours in conducting biochemical processes, physical and behavioral needs of living entities) etc..
Although the term refers to the biological clock cycle operation of all hereditary processes, is used most commonly as a method of marking a woman's ability to conceive / birth (generating hormones, hormonal processes, from puberty until menopause), describing processes within the body that are the subject of this internal rhythm - loss of fertility with age once.
As "read" biological clock?
For most biological clock is pretext to discuss the possibility of becoming a parent. When various discussions about this possibility, plans, concerns becoming more common for various aspects of conception and misconceptions are highlighted by one of the couple - it's time to listen to your biological clock and know him "read ". While for some biological clock or by cramps warns of ovulation periods (women) or feelings of maternal / paternal children from strangers, others feel a strong desire to have a child.
Young optimistic that they want to take ownership for this attribute enjoyable but difficult and often celebrates the commitment and take it to each other through conception of a child. Others believe that a baby will save their relationship, life. Interpretation personal needs and desires, the expectations I help you "read" biological clock.
Despite the reception of certain signals from your biological clock, young people tend to ignore especially lack the necessary financial support and increase a child's conception, the main reason that couples disagree on timing to conceive or adopt. Stress and lack of financial security are the most powerful "contraceptives" and time passes in your defavorarea.
Age and concept - clock
Female biological clock
For women, every anniversary, every menses inseamana another reminder of the passage of time and her biological clock that counts the biological rhythm and the ability to have children. But besides this there is a biological clock biological rhythm that will set the general daily biological rhythms - and it can be set to a maximum of fertility.
These biological rimuri day - when certain desires and needs are appearing on a regular basis: fatigue, urge to make exercise or sex. This small internal clock located in the hypothalamus, regulates heart rate and body temperature, sensations and moods mood and sexual desire and hormone production - so influence a woman's ability to become pregnant.

Criteria of "reading" the biological clock
Egg timer
Although it seems unbelievable, a woman's biological clock starts operating even before birth. At an age of 20 weeks (in the womb), female fetus has about 7 million eggs, but by the time of birth that number drops to 1-2 million for the next 35-40 years to eliminate female life some of these eggs through the process of ovulation. The remaining eggs are degenerate and die gradually until she enters the menopazua around the age of 50 years.
According to the American Society for Reproductive Medicine healthy woman, 30 years old, has 20% chance a month to become pregnant, while a woman of 40 years has only 5% chance a month to get pregnant . Although age seems to be a decisive factor in assessing female fertility, there are other factors that influence ovarian reserve for conception.
Women are born with a finite number of eggs (oocytes), a number that varies from one woman to another, and each month during the menstrual cycle about 1,000 eggs mature and only one has sanasa be fertilized by a sperm.
Assessment of ovarian reserve (reserve of eggs)
To design, follicular stimulating hormone (FSH) must trigger the development of follicular cells in the ovaries that contain immature eggs. These eggs mature in a process called ovulation and travels through the Fallopian tubes, the uterus. If an egg is fertilized by a sperm in this passage, it will attach to the uterine wall and will "fix" this task.
As she has more eggs in the ovaries and how their quality is higher (not started the process of degeneration and did not suffer deformities) the greater the chances of conceiving. To assess the woman's egg reserve required a series of blood tests: FSH level, FCTC (Clomiphene Citrate Challenge Test), Inhibin B
Ovarian volume may reflect the number of follicles remaining in the ovaries and thus can assess ovarian reserve and reproductive age. Ovarian volume (size as the 3 dimensions) can be measured with a transvaginal sonogram (ultrasound) vaginal probe. Sonograms conclusion: small ovaries with a small number of follicles are correlated with low ovarian reserve, while larger ovaries with a large number of follicles are correlated with higher ovarian reserve (reserve of eggs high).
Eggs and degeneration with age
Oocytes from ovaries decrease in number with age:
*** Between 18-30 years - remain around 80% and is optimum fertility;
*** Between 31-37 years - about 66% and fertility rate gets a downtrend;
*** Between 38-41 years - 33% and infertility increases with the highest rate.
Between 41-50 years *** - 6, 66% and reach the end point of your fertility
Risk of female infertility and age
*** Late 20 - early 30 - 84% of women are fertile;
*** Middle age of 30 years - 39 - three-quarters of women are fertile;
*** Until reaching the age of 40 years 50% of women become infertile.
Age and concept - clock
These data on female fertility and age were assessed risks if a couple of medically healthy. As you age, but certain bodily functions deteriorate, there is a risk malfunctionarii reproductive organs, diseases such as endometriosis (presence of uterine scar tissue outside the normal areas such as fallopian terrine) and uterine fibroids (cell mass that develops in the uterus ).

Male biological clock
Male biological clock exists, but it is a taboo, compared to female infertility, this is mainly due to pride, male pride, to recognize and accept that sperm quality has lost over time or due to harmful factors, and aa close link existing between virility and masculinity.
Biological clock affects male hormone levels in the body, fertility and genetic quality of sperm. For a full understanding of these phenomena is necessary but a deeper cellular and biochemical mechanisms behind testicular aging in order to determine which method to reset the biological clock there to save time.

Male biological clock is driven by testosterone, the male sex hormone. Decreased testosterone levels can lead to weight gain, increased estrogen levels and reduce future production of testosterone in the body. Weight gain (especially in the trunk, abdomen) leads to heart disease, reducing blood flow and thus erectile dysfunction may occur.
Men continue to produce sperm throughout life (this explains the trend of fathers of 70, 80, 90 years), but what affects the biological clock is quantity, motility (ability to perform certain movements organs) and sperm quality. Men aged 30-50 years experiencing a 30% decrease in the volume of semen produced, and in terms of motility loses 37% of capacity.
The quality of sperm is very important not only for conception but also for the design of a viable fetus. Sperm whose DNA has been altered or deformed, genetically altered, causing fetal defects. From this point of view older men produce sperm with a deformity 5 times higher than young men (20% damage around the age of 35, compared to only 5% at 25 years).

Male fertility declines around the age of 24-25 years. And the chances of conception in a period of 6 months from the decision and lack of protection against pregnancy during sexual acts fall by 2% per year over this age.
Research in the field of embryology has revealed that as babratul ages, it accumulates a number of genetic defects in sperm. In young men but damage is minor and can be repaired inside the fertilized egg, but to older men suffering amount of DNA damage is far greater and exceeds the repair capacity of natural mechanisms of the body.
Decreases more sperm around the age of 35 years, which means fewer chances of fertilization of an egg and pregnancies are at greater risk of loss. Gradually lose speed sperm motility, which means accuracy again reducing chances of fertilization.
Age and concept - clock
There are known rare diseases associated with conception and birth of a child with a man aged: men over 40 have a higher risk of conceiving a child with autism, schizophrenia, piticism, heart defects, craniofacial dimorphism, epilepsy, cancer , Down syndrome. Paternal age may also be associated with a low level of intelligence of the child at greater risk of developing breast cancer and shorten life (conception of a female child by a man over 45 years).

Partner's risk of miscarriage and male age (European Society of Human Reproduction and Embryology)
- 17% for men older than 34 years;
- 20% - for a man aged 35-39 years;
- Over 32% if the man has more than 44 years.

Male biological clock affects the life of a couple conceiving
- Women over 45, whose husbands are over 45 years old are required for 5 times longer to achieve conception than those of the same age group and with partners aged 25 years (study published in the journal " Fertility and Sterility ") - time concept is 4-5 times regardless of woman's age;
- Chances of conceiving a period of six months reduced by 2% each year after exceeding the age of 25 years (according to a study published in the journal "Human Reproduction"), and the chances of conception within 12 months decreased by 3% each year;
- Women whose husbands are up to five years older than they have less chance of conceiving than those with partners of the same age with them.
Clock differences between female and male biological clock
- Men (in general) do not feel the same burning desire and do not have the same sense of pressure concept (reminds monthly menstrual cycle of women during their childbearing as entering a downtrend);
- Men feel more like pressure to "feed" to secure the future of the family, while women feel the pressure to conceive to constitute a family;
- A woman's estrogen level decreases faster than the level of testosterone in men: an age of decreasing estrogen levels in women is irreversible (after 35 years), while in men testosterone levels start to decline from 25 years, but at a much slower pace;
- While it installs menopausal women (ovulation process is interrupted), andropause in men (all physiological and psychological changes caused by decreased production of male sex hormones androngeni-) is marked by a disruption of generating sperm.
Similarities between the biological clock and clock male female
Both women and the mean age Babri decreased production of specific sex hormones (estrogen, testosterone) that generates a decline in fertility and a higher risk of conceiving a child with genetic defects.
Just because man can produce sperm, does not mean that it will be of good quality: volume, motility and sperm quality declines.
Age and concept - clock
Unconscious body clock dictates each individual (female or male) when having sex to conceive. According to studies by the University of Modena, Italy, men produce more sperm afternoon and evening libido has increased levels while ovualtie process starts at midnight.
It's wise to start from a couple of design process around the age of 20-30 years to avoid any inconvenience caused by stress, infertility, birth defects, etc..

But if delaying the moment of conception has objective reasons (lack of a partner, emotional instability, financial, etc.) there is a second chance: luckily there are some ways to reset the biological clock to prolong the childbearing: learn to take advantage of own body rhythms to enhance your sexual performance and pleasure. Reset your biological clocks for maximum fertility will accelerate conception.
