The main reason fertility decreases with age is because the quality of a woman's eggs declines as she gets older. And, as women are born with all the eggs they will ever have, older women have fewer eggs. The natural aging process also means higher chances of miscarriage and having a child with a genetic condition.
Based on that data, the researchers estimate that lifetime prevalence of infertility – representing the proportion of people who have ever experienced infertility in their reproductive life – was 17.5% in 2022.
Australia has experienced a long-term decline in its TFR. Following a long baby boom that culminated in a TFR of 3.56 children per woman in 1961, fertility fell below the replacement level of 2.1 children per woman in 1975, and by 2020 the TFR had fallen to 1.58, its lowest recorded level (Figure 1).
Large numbers of people are affected by infertility in their lifetime, according to a new report published today by WHO. Around 17.5% of the adult population – roughly 1 in 6 worldwide – experience infertility, showing the urgent need to increase access to affordable, high-quality fertility care for those in need.
What is infertility? Infertility is defined as the inability to conceive a pregnancy after 12 months of unprotected sexual intercourse. It affects about 1 in 6 Australian couples of reproductive age.
One key reason fertility rates dropped and remain low is a global rise in education, according to Vegard Skirbekk, a population economist and the author of the 2022 book “Decline and Prosper!
In 2020-21, the fertility rate was 1.66 babies per woman, similar to the rate recorded in 2018-19. In 2019-20, the rate had fallen to 1.61 babies per woman. According to the report, the data suggests people “adapted to the uncertainty of the pandemic and quickly caught-up on delayed childbearing plans”.
ABS Director of Demography, Beidar Cho said: “The record low total fertility rate can be attributed to fewer births and birth registrations in most jurisdictions in a year marked by COVID-19 disruptions.”
The total fertility rate, a measure that gives the average number of children an Australian woman would have during her lifetime should she experience the age-specific fertility rates present at the time was 1.7 births per woman in 2021. This was up from the 1.59 for 2020, the lowest total fertility rate ever reported.
Retrieved June 14, 2023, from www.marchofdimes.org/peristats. In the United States, the highest fertility rates (per 1,000 women ages 15-44) during 2018-2020 (average) were to Hispanic women (64.8), followed by blacks (62.6), American Indian/Alaska Natives (60.8), Asian/Pacific Islanders (55.6) and Whites (55.3).
What Causes Infertility? Problems with ovulation are the most common reasons for infertility in women. A woman's age, hormonal imbalances, weight, exposure to chemicals or radiation and cigarette smoking all have an impact on fertility.

South Korea has the world's lowest fertility rate, a struggle with lessons for us all. A woman holding her daughter looks at a view of Seoul in 2019. The fertility rate in South Korea, which has the world's lowest rate, hit 0.78 in February.
More couples are conceiving through IVF treatment in Australia than ever before, a newly published report suggests. The success rate has improved by 18% in the past decade across Australia and New Zealand, with improvements in multiple areas of assistive reproductive treatment (ART) credited for the change.
Australia's TFR rose from 2.1 babies per woman in 1934 to a peak of 3.55 babies per woman in 1961 during the 'baby boom' years. Since then, the TFR has fallen almost continuously, reflecting Australian women gradually having children later in life, and having fewer children when they do.
The current fertility rate for Australia in 2023 is 1.784 births per woman, a 0.56% decline from 2022. The fertility rate for Australia in 2022 was 1.794 births per woman, a 0.5% decline from 2021. The fertility rate for Australia in 2021 was 1.803 births per woman, a 0.55% decline from 2020.
Australia's population is predicted to be 4% or 1.2 million people smaller than previously forecast in 2032-33 because of slowed migration. The ageing population means Australia is reliant on migration to grow, as migrants tend to be younger and higher skilled, which boosts the nation's productivity.
The most common birthday in Australia is September 17th! The least common birthday (you may have guessed it is) is Christmas Day, the 25th of December. If you are inclined to count leap years in the mix then the 29th February is the least common birthday, but only because they occur once every 4 years.
Australian dads are among the oldest in the world, and we're not getting any younger. According to the Australian Bureau of Statistics' data on registered births in 2020, the median age of fathers is 33.6 years, rising from 28.5 years in 1975, when data was first collated.
In a recent New York Times opinion piece, author Jessica Grose asks, “Are Men the Overlooked Reason for the Fertility Decline?” She provides compelling evidence to suggest that this phenomenon is not just about women delaying childbearing. Men, too, are contributing to declining fertility rates.
Dropping birth rates are a result of a number of reasons, such as growing living expenses, an increase in the number of women in the workforce, as well as easier access to contraception, which encourages women to have fewer children. The declining social and cultural values are a major factor in Japan's low birth rate.
Pregnancy after age 45 years is infrequent and the mother and baby should be considered as a high risk. There is a greater incidence of spontaneous abortion, gestational trophoblastic disease and chromosomal abnormalities in the fetus.
Some people feel they cannot afford it. Health/medical reasons. This is one of the top reasons people decide not to have children—a risk to their own health and well-being, or inability to conceive. Other caretaking responsibilities and/or other children in their lives.
