In the United States, 10% to 15% of couples are infertile. Infertility is defined as not being able to get pregnant despite having frequent, unprotected sex for at least a year for most couples. Infertility may result from an issue with either you or your partner, or a combination of factors that prevent pregnancy.
It refers to when a couple have been unable to conceive after 12 months of unprotected sexual intercourse. About one in 6 Australian couples of reproductive age experiences fertility problems.
Infertility is commonly caused by problems with ovulation (the monthly release of an egg from the ovaries). Some problems stop an egg being released at all, while others prevent an egg being released during some cycles but not others. Ovulation problems can be a result of: polycystic ovary syndrome (PCOS)
In the United States, among heterosexual women aged 15 to 49 years with no prior births, about 1 in 5 (19%) are unable to get pregnant after one year of trying (infertility). Also, about 1 in 4 (26%) women in this group have difficulty getting pregnant or carrying a pregnancy to term (impaired fecundity).
Infertility is a condition where you cannot get pregnant after one year of trying to conceive. In women, cause of infertility can include endometriosis, uterine fibroids and thyroid disease. Men with fertility problems may have a low sperm count or low testosterone. The risk of infertility increases as you age.
The main symptom of infertility is not getting pregnant. There may be no other obvious symptoms. Sometimes, women with infertility may have irregular or absent menstrual periods. In some cases, men with infertility may have some signs of hormonal problems, such as changes in hair growth or sexual function.
Polycystic ovary syndrome (PCOS).
It's the most common cause of female infertility.
If you don't get pregnant after one year of trying, talk to your doctor. If you're 35 years old or older, you should see your doctor after six months of trying without success to get pregnant. If you have a possible sign of infertility before the one-year mark, your doctor can run some basic fertility tests.
Your doctor will give you a pelvic exam. They may also use an ultrasound to look at your ovaries and uterus, and give you a blood test to check your hormones. Sometimes you'll need to start tracking your ovulation patterns by checking your cervical mucus, taking your temperature, or using home ovulation tests.
By age 30, fertility (the ability to get pregnant) starts to decline. This decline becomes more rapid once you reach your mid-30s. By 45, fertility has declined so much that getting pregnant naturally is unlikely for most women.
Does stress cause infertility? While it's unlikely that stress alone can cause infertility, stress interferes with a woman's ability to get pregnant. Research has shown that women with a history of depression are twice as likely to experience infertility. Anxiety also can prolong the time needed to achieve pregnancy.
In 85% to 90% of cases, infertility is treated with conventional medical therapies, such as medication or surgery. If fertility treatments are unsuccessful, it is possible to use eggs or sperm donated by a third party or to have another woman carry a fetus. Select a category of treatment to learn more.
Fertility rates in Australia and around the world
Dr Allen says the decline in the average number of children per woman is a result of increased education and paid employment for women. Women are starting families later and consequently having fewer children, and more people are choosing to be child-free.
Greater Melbourne's total fertility rate had one of the largest declines, falling from 1.58 in 2019 to 1.46 in 2021. This decline is related to COVID-19 impacting on people's decisions to have children.
Fertility rate calculations are typically simplified by two standard assumptions. First, it assumes that each woman's fertility follows general age-specific fertility trends throughout her childbearing years (peaking in her early 30's).
The most common causes of female infertility include problems with ovulation, damage to fallopian tubes or uterus, or problems with the cervix. Age can contribute to infertility because as a woman ages, her fertility naturally tends to decrease.
That said, the majority of couples will conceive within 1 year of trying. It is possible but less common to conceive in the first month or within 6 months. A couple looking to conceive should track ovulation and have regular vaginal intercourse in the days leading up to ovulation.
Couples experiencing infertility can often be associated with genetic factors. From inherited chromosomal abnormalities to gene mutations, both males and females have different outcomes from both these factors. These include: Deletion whereby a piece of a chromosome is missing.
The most common overall cause of female infertility is the failure to ovulate, which occurs in 40% of women with infertility issues. Not ovulating can result from several causes, such as: Ovarian or gynecological conditions, such as primary ovarian insufficiency (POI) or polycystic ovary syndrome (PCOS)
If you have a healthy weight and you're thinking of becoming pregnant soon, consider limiting vigorous physical activity to less than five hours a week. Avoid exposure to toxins. Environmental pollutants and toxins — such as pesticides, dry-cleaning solvents and lead — can adversely affect fertility.
Although infertility is not a life-threatening issue, it is still considered a stressful life experience for couples. The high stress of infertility might be attributed to the fact having a child is considered to be important in general society (2).
These include: age – fertility declines with age. weight – being overweight or obese (having a BMI of 30 or over) reduces fertility; in women, being overweight or severely underweight can affect ovulation. sexually transmitted infections (STIs) – several STIs, including chlamydia, can affect fertility.
