Till what age a woman can be pregnant
Is there really a "right time" to get pregnant? As it turns out, everyone you ask will likely give you a different answer, but take it from these moms who've been there and know firsthand. Being able to create life is undeniably one of the most beautiful gifts bestowed on women, but it also comes with a very loud and constantly ticking clock. In fact, you'd be hard pressed to find a woman who's not uncomfortably aware of her biological clock and that her chances for getting pregnant and raising a family are up against it. But while a woman might be in her fertile prime in her 20s, this decade is not an ideal time for many women to tackle pregnancy and parenting. Some women aren't even ready in their early 30s.SEE VIDEO BY TOPIC: Age and Fertility - How old is too old to have a baby?

Age and female fertility
Fertility changes with age. Both males and females become fertile in their teens following puberty. For girls, the beginning of their reproductive years is marked by the onset of ovulation and menstruation. It is commonly understood that after menopause women are no longer able to become pregnant.
Generally, reproductive potential decreases as women get older, and fertility can be expected to end 5 to 10 years before menopause. Even though women today are healthier and taking better care of themselves than ever before, improved health in later life does not offset the natural age-related decline in fertility. It is important to understand that fertility declines as a woman ages due to the normal age-related decrease in the number of eggs that remain in her ovaries. This decline may take place much sooner than most women expect.
During their reproductive years, women have regular monthly menstrual periods because they ovulate regularly each month. The pituitary hormone that stimulates the ovaries is called follicle-stimulating hormone FSH. Normally, only one of those follicles will reach maturity and release an egg ovulate ; the remainder gradually will stop growing and degenerate.
Pregnancy results if the egg becomes fertilized and implants in the lining of the uterus endometrium. If pregnancy does not occur, the endometrium is shed as the menstrual flow and the cycle begins again.
In their early teens, girls often have irregular ovulation resulting in irregular menstrual cycles, but by age 16 they should have established regular ovulation resulting in regular periods. As time passes, she will begin to skip ovulation resulting in missed periods. Ultimately, periods become increasingly infrequent until they cease completely.
When a woman has not had a menstrual period for 1 full year, she is said to be in menopause. As women age, fertility declines due to normal, age-related changes that occur in the ovaries. Unlike men, who continue to produce sperm throughout their lives, a woman is born with all the egg-containing follicles in her ovaries that she will ever have.
At birth there are about one million follicles. By puberty that number will have dropped to about , Of the follicles remaining at puberty, only about will be ovulated during the reproductive years.
The majority of follicles are not used up by ovulation, but through an ongoing gradual process of loss called atresia. Atresia is a degenerative process that occurs regardless of whether you are pregnant, have normal menstrual cycles, use birth control, or are undergoing infertility treatment. Smokers appear to experience menopause about 1 year earlier than non-smokers.
Fertility gradually declines in the 30s, particularly after age That means that for every fertile year-old women trying to get pregnant in 1 cycle, 20 will be successful and the other 80 will have to try again. Women do not remain fertile until menopause. The average age for menopause is 51, but most women become unable to have a successful pregnancy sometime in their mids. These percentages are true for natural conception as well as conception using fertility treatment, including in vitro fertilization IVF.
The age-related loss of female fertility happens because both the quality and the quantity of eggs gradually decline. Sperm quality deteriorates somewhat as men get older, but it generally does not become a problem before a man is in his 60s. Though not as abrupt or noticeable as the changes in women, changes in fertility and sexual functioning do occur in men as they grow older. Despite these changes, there is no maximum age at which a man cannot father a child, as evidenced by men in their 60s and 70s conceiving with younger partners.
As men age, their testes tend to get smaller and softer, and sperm morphology shape and motility movement tend to decline. In addition, there is a slightly higher risk of gene defects in their sperm. Aging men may develop medical illnesses that adversely affect their sexual and reproductive function. Not all men experience significant changes in reproductive or sexual functioning as they age, especially men who maintain good health over the years.
Decreased libido may be related to low levels of testosterone. Women become less likely to become pregnant and more likely to have miscarriages because egg quality decreases as the number of remaining eggs dwindle in number. These changes are most noted as she reaches her mid-to-late 30s. An important change in egg quality is the frequency of genetic abnormalities called aneuploidy too many or too few chromosomes in the egg.
At fertilization, a normal egg should have 23 chromosomes, so that when it is fertilized by a sperm also having 23 chromosomes, the resulting embryo will have the normal total of 46 chromosomes. As a woman gets older, more and more of her eggs have either too few or too many chromosomes.
That means that if fertilization occurs, the embryo also will have too many or too few chromosomes. Most people are familiar with Down syndrome, a condition that results when the embryo has an extra chromosome Most embryos with too many or too few chromosomes do not result in pregnancy at all or result in miscarriage.
This helps explain the lower chance of pregnancy and higher chance of miscarriage in older women. Since women are born with all of the follicles they will ever have, the pool of waiting follicles is gradually used up.
As ovarian reserve declines, the follicles become less and less sensitive to FSH stimulation, so that they require more stimulation for an egg to mature and ovulate. At first, periods may come closer together resulting in short cycles, 21 to 25 days apart. Eventually, the follicles become unable to respond well enough to consistently ovulate, resulting in long, irregular cycles.
Diminished ovarian reserve is usually age-related and occurs due to the natural loss of eggs and decrease in the average quality of the eggs that remain. However, young women may have reduced ovarian reserve due to smoking, family history of premature menopause, and prior ovarian surgery. Young women may have diminished ovarian reserve even if they have no known risk factors. There are medical tests for ovarian reserve, but none have been proven to reliably predict the possibility of becoming pregnant.
These tests do not determine whether or not a woman can become pregnant, but they can determine that age-related changes of the ovaries have begun. Women with poor ovarian reserve have a lower chance of becoming pregnant than women with normal ovarian reserve in their same age group. High levels of FSH or estrogen indicate that ovarian reserve is low.
However, many women with diminished ovarian reserve will have normal levels of FSH on day 3, so a normal day-3 FSH does not confirm normal ovarian reserve. Other tests of ovarian reserve that are sometimes utilized include the clomiphene citrate challenge test CCCT and ultrasound assessment of follicle numbers, called the antral follicle count.
Infertility usually is diagnosed if a woman has not become pregnant after 1 year of unprotected intercourse i. However, if she is 35 or older, the evaluation should begin after 6 months of trying unsuccessfully to conceive. If a couple has an obvious medical problem affecting their ability to conceive, such as absence of periods amenorrhea , sexual dysfunction, a history of pelvic disease, or prior surgery, they should begin the infertility evaluation immediately.
Fertility tests may include ovulation detection and evaluation of the fallopian tubes, cervix, and uterus. The male partner will have a semen analysis. Most testing can be completed within 6 months, and appropriate treatment can be started immediately after the evaluation is completed. Women who have a medical disorder, such as high blood pressure or diabetes, should talk with their clinical care provider before attempting pregnancy.
It is important that health problems are under control. The clinical care provider may suggest a change in medication or general health care before pregnancy as there are increased risks for older women. Conditions such as high blood pressure or diabetes develop more commonly in women who conceive after age Special monitoring and testing may be recommended during pregnancy. Preconception counseling is often beneficial as well.
Children born to women over age 35 have a higher risk of chromosomal problems. Women can choose to discuss these risks with their clinical care provider or a genetic counselor prior to attempting pregnancy.
Prenatal testing may be performed after conception to check for certain birth defects. Amniocentesis and chorionic villus sampling are two methods of prenatal testing. Blood testing and ultrasound also may be used as screening tests for certain birth defects. Many parents want to know as much about the pregnancy as possible so they can make informed decisions.
If a cause for infertility is identified, the clinical care provider may suggest a specific treatment. This procedure is called intrauterine insemination IUI and causes minimal discomfort. For more information on assisted reproductive technologies, refer to the ASRM patient information booklet titled Assisted Reproductive Technologies.
Egg donation, which involves the use of eggs donated by another woman who is typically in her 20s or early 30s, is highly successful. The high success rate with egg donation confirms that egg quality associated with age is the primary barrier to pregnancy in older women.
If you are over 40, your chance of successful pregnancy is much higher in IVF cycles using donor eggs, but many couples or single women in their early 40s will choose to accept the lower chance of become pregnant and use their own eggs. At the same time, the egg recipient is given hormone therapy to prepare her uterus to receive the fertilized eggs embryos.
Any embryos that are not transferred may be frozen cryopreserved for a future cycle. Donor-egg IVF offers a woman an opportunity to experience pregnancy, birth, and motherhood. The child, however, will not be genetically related to her but will be genetically related to the father and the egg donor. Many programs recommend counseling so that all parties in a donor-egg agreement understand the ethical, legal, psychological, and social issues involved.
Because success depends heavily upon the quality of eggs that are donated, women in their 20s with proven fertility are ideal donors. Women who wish to delay childbearing until their late 30s or early 40s may consider methods of fertility preservation such as freezing of embryos after IVF or retrieving and freezing eggs for later use. The success of embryo freezing cryopreservation is well established, but it requires that the woman have a male partner or use donor sperm.
Egg freezing for preservation of fertility is a new technology that shows promise for success. Age remains a problem faced by women interested in using elective egg freezing. As the age of women undergoing egg freezing increases, the outcomes of assisted reproductive technology cycles utilizing their frozen eggs become less favorable. New technologies that will allow testing of embryos for chromosomal abnormalities are currently being investigated.
This technology applies to embryos created during a cycle of IVF. It may be particularly useful for older women.
Are You Pregnant at 45?
Fertility changes with age. Both males and females become fertile in their teens following puberty. For girls, the beginning of their reproductive years is marked by the onset of ovulation and menstruation. It is commonly understood that after menopause women are no longer able to become pregnant. Generally, reproductive potential decreases as women get older, and fertility can be expected to end 5 to 10 years before menopause.
Why age matters for men and women who want to have a family. We all know someone who had a healthy baby in their late 30s or early 40s. But of all people who try for a baby at a later age, many will not have the baby they hoped to have. Across a population, women younger than 35 and men younger than 40 have a better chance of having a child than people who are older.
4 Myths About Getting Pregnant After 35 — Debunked
If conception isn't an option, adoption might be. Just take Hoda Kotb, 52, who recently adopted a baby girl. Technology has changed. The younger the patient gets pregnant, the healthier the pregnancy will be. After age 35, pregnancy is more difficult because of less frequent ovulation. Past age 40, freezing eggs or embryos will not have a great success — less than 9 percent result in live birth, Coddington said. Even though men can conceive later in life, men over 40 are at high risk of having a child with complications like Autism or still birth, Coddington said. If a woman looking to freeze eggs has found the partner she wishes to have children with, she could choose to freeze embryos instead, which remain more viable than eggs because of the freezing process. Eggs or embryos can be implanted in a woman up to age
Age and Fertility (booklet)
Female fertility is affected by age. Age is thus a major fertility factor for women. Menarche , the first menstrual period, usually occurs around 12—13, although it may happen earlier or later, depending on each girl. After puberty , female fertility increases and then decreases, with advanced maternal age causing an increased risk of female infertility.
