When does fertility start to decrease?

More women today find they want to put off pregnancy until their careers are well established, or until they've gotten more life experience. However, research shows that pregnancies in women over the age of 35 suffer from more problems than those in younger women. How great are the risks compared with the benefits, and what do you really need to be concerned about? \nHow Old is Too Old to Have a Baby?\nAccording to the Mayo Clinic, a woman's fertility peaks between the ages of 20 and 24. However, fertility rates remain relatively constant through the early 30s, after which they begin to decline:\n\nAt age 30 to 35, fertility is 15 to 20 percent below maximum. From age 35 to 39, the decrease is 25 to 50 percent. From 40 to 45, the decrease is 50 to 95 percent.\n\nTechnically, any woman who has not gone through menopause, and who does not have other reproductive problems, can become pregnant. Successful pregnancies have been reported in women as old as 59.\n\nPregnancy Risks After 35\nThe risk of miscarriage increases after age 35; by the early 40s, more than 50 percent of pregnancies end in miscarriage. Many of these occur at an early stage and may not even be detected, or may be mistaken for a late period. The majority of these miscarriages are due to the chromosomal abnormalities in the fetus.\n\nOther age-related factors affecting fertility include less frequent and/or irregular ovulation, and endometriosis, in which tissue that attaches to the ovaries or fallopian tubes interferes with conception.\n\nWhen they do get pregnant, women older than 35 may have a higher risk of developing gestational diabetes, preeclampsia, and placenta previa. There is also a potentially higher risk of having a baby with low birth weight, and of chromosomal abnormalities such as Down syndrome.\n\nAiming for a Positive Pregnancy\nAlthough older women may find it somewhat harder to achieve pregnancy, the overall outcomes are excellent. In fact, birth rates for mothers in their 30s and 40s have increased dramatically over the past 25 years. According to the National Center for Health Statistics, the birth rate for women age 35 to 39 nearly doubled between 1978 and 1998. Between 1981 and 1997, the birth rate for women in their 40s increased 92 percent.\n\nIf you're over 35 and thinking of getting pregnant, a few simple tips will help minimize the risks: \n\nStart taking prenatal vitamins \nSee your doctor for prepregnancy checkups \nEat well \nExercise regularly \nCut out nicotine, alcohol, and drugs \n\nFinally, if you don't succeed in getting pregnant within six months, see a reproductive endocrinologist (fertility specialist) to discuss next steps.\n\nSources: The Mayo Clinic Complete Book of Pregnancy and Baby's First Year (Morrow, 1994); March of Dimes: 888-MODIMES, www.modimes.org, www.nacersano.org\n\nThe information on this Web site is designed for educational purposes only.

Human sperms take about 65 days to completely develop.

I think that, in addition to the answer provided above, that there are more fertility problems that we are aware of.  Twenty or thirty years ago, nobody discussed fertility issues, and we didn't see advertisements about fertility clinics.  Now that those treatments are available, it's brought fertility issues into the public eye more than ever before.

The birth rate would definitely be lower. But it may not completely stop people from having sex.

I don't think that marriage will be so important as it is nowadays, and even nowadays the importance has dwindled down. Less people are eager to get married, and less women want to have children. So, in the next 20-25 years I think that the birth rate will have significantly gone down, and so will the marriage rate. Maybe more dads will be staying home and taking care of the kids, while moms will be the ones bringing home the bread.

Sorry! It decreases with age. After 30 yrs old there is a decline in the amount of testosterone produced.

Check out a book called Taking Charge of Your Fertility. I'm pretty sure that's the title. It helps you read the signs so you know when you ovulate and helps you decide the best time for intercourse. \n\nThere's also a book called The Fastest Way To Get Pregnant Naturally.\n\nIf you've been trying for more than a year, you may want to see a specialist to rule out any fertility problems.\n\nAnd in answer to the lady's question below: 5 children is NOT enough! I have 7. :-)

Depends on the family traits, hormones and diet. Usually for women at menopause. For men, can start at the early 20's but usually mid 30's.

There's a book called the Art of Natural Family Planning.  I think that's what it is called.  But it teaches how to tell when a woman is ovulating from taking her temperature, and other signs to look for to know the fertile times. It's a great method.  I did not enjoy the pill.  I was moody all the time and I didn't know what was going on with my body. This other method is great.  I know what is going on in my body.  There's more control.  Don't do anything permanent.  SOmeday you might want kids.

Most people usually are pregnant within six months, a good portion more by the end of the first year.  No need to worry yet.  It may be more difficult to get pregnant because your periods are irregular, so predicting ovaulation can be hard. There are ways you can detect it, though.  You can start by taking your temp every morning when you first get up.  About 10 days after your last period started, you should begin to ovulate.  When this happens your basal temp will be slightly elevated.\nThere are dietary changes you can make as well to increase your chances of becoming pregnant.  FIrst and foremost, make sure you are taking a prenatal vitmain if you aren't already.  Decrease your sugar intake.  Excess sugar has been linked to fertility difficulties.  Eating foods high in zinc have been linked to reproductive health as well.\nI wish you lots of luck and hope there is a baby in your near future!!

If it is truly menopause then unfortunately yes. Menopause starts when the body stops producing eggs and the hormones to support pregnancy. At least that is what I understand it to be. I would go to a dr. immediately and see. If it hasn't truly started yet there may still be a chance. Perhaps even freezing any remaining eggs or embryo if you are already married and know who you want to have a child with but it will be costly.

go to http://www.mymonthlycycles.com and put in your period info and it will calculate when you will ovulate and be fertile.\n\n\nOne of the hallmarks of the current generation is that women are choosing to have children later in life and it is likely that this trend will continue. On average, women today are having two children with approximately four years time between the first and second births. Between 1985 and 1994 the proportion of births to women in their 20s decreased from 62 percent to 53 percent, while the proportion of births to women 30 - 44 years of age increased from 25 percent to 34 percent. Since the mid 1970s there has been a four-fold increase in the percent of first births to women 30 years and older. \n\nOvulation is the term used to define the release of an egg (usually one, though sometimes more) from a woman’s ovary. Conception occurs when a sperm fertilizes the egg. While sperm can survive for several days inside a woman’s reproductive tract, an egg can only survive for up to 24 hours after ovulation. This puts a limitation on the time when conception is most likely to occur. According to a recent survey conducted at the World Congress on Fertility and Sterility, 20 percent of the problems in conceiving are due to a couple’s failure to time intercourse correctly during the woman’s fertile time period.\n\nThe Opinion Research Corporation International (ORC) found that most women don’t know when they can become pregnant. Nearly all women (98 percent) of reproductive age are unclear about how many days each month it is possible to get pregnant, and more than half (52 percent) of women aren’t sure when those fertile days occur during their cycle. Most parents do not know the day(s) on which their children were conceived.\n\nTo increase chances of becoming pregnant, women should monitor their body’s fertile time period - the time that sperm can survive within a woman’s reproductive tract until ovulation and fertilization can occur. A woman’s most fertile period is typically several days (usually no more than 5-6) ending on the day after ovulation. Because menstrual cycles vary from one woman to another and even from one cycle to the next in the same woman, identifying a woman’s fertile time period can be challenging. However there are several methods a woman can use to determine when she is most likely to conceive: \n\nCalendar - A woman can chart her menstrual cycle on a calendar to determine the days she is most likely to ovulate. \nBasal Body Temperature (BBT) - The BBT is a woman’s temperature first thing in the morning, before getting up or doing any activity. In a normal menstrual cycle, a woman’s BBT rises almost one degree from just after ovulation through the beginning of her next cycle. \nCervical Mucus - Most of the time the cervix produces a mucus that protects the body from sperm, bacteria and other organisms. For several days each month, the consistency of the mucus changes to allow sperm to enter the fallopian tubes. By monitoring these changes, a woman can determine her fertile time period. \nSymptothermal - Charting a combination of fertility indicators like cervical secretions and BBT can often help to indicate a woman’s fertile time period. \nThe above charting methods require women to record the secondary signs of fertility caused by changes in hormones. Because these conditions can be affected by factors such as infections or medications, they require careful monitoring and analysis, and they are never 100% reliable. An alternative to these methods is measuring changes in hormone levels. An increase in the level of estrogen marks the beginning of most women’s fertile phase, while an increase in the luteinizing hormone (LH) level signals that ovulation will occur soon - usually within approximately 24 to 36 hours.\n\nThe fertility monitor is a relatively new approach designed to provide daily information about a woman’s fertile time period. The monitor recor
