About Age and Fertility

What age are women most fertile?

Women are most fertile from their late teens to late twenties. After 30, fertility declines more rapidly. By age 36, the chance of conceiving each month drops to about half compared to early 20s, and by age 41, it decreases to just 4% per month.

This decline is due to a decrease in the number and quality of eggs. Women are born with about 2 million eggs, which reduce to around 400,000 by puberty, and continue to decline.

Men's fertility also diminishes with age, though less drastically than women's. Male factors account for over 40% of infertility cases, often influenced by sperm abnormalities and reduced sperm counts as they age.

Male Fertility and Infertility

What percentage of infertility cases are due to male fertility issues?
About 30% of infertility cases in Australia are due to male fertility issues. Additionally, another 30% of cases involve problems with both male and female fertility.
How common are low sperm levels among men?
Approximately 1 in 20 Australian men have low sperm levels, and 1 in every 100 men has no sperm at all.
What causes male infertility?
Male infertility can be caused by various factors, including low sperm quality or quantity, issues with sperm reaching the egg, medical conditions or hormonal problems, lifestyle or environmental factors, age, and sperm DNA fragmentation.
How does age affect male fertility?
Men's fertility starts to decline around age 35, making them about half as fertile as they were at 25. After age 55, their fertility decreases dramatically.
How is male fertility evaluated?
Male fertility can be evaluated through medical history, physical examination, blood and urine tests, semen analysis, and the Sperm Chromatin Integrity Test (SCIT) for sperm DNA fragmentation. Further tests may include genetic testing, ultrasound or MRI, testicular biopsies, fine needle aspirations, and antisperm antibody tests.

Female Fertility

What factors can impact female fertility?
Female fertility can be affected by various factors, including a womans age, weight, and medical conditions such as endometriosis, polycystic ovarian syndrome (PCOS), or fibroids. These conditions often require treatment at a fertility clinic like Genea before conception can occur.
What is the fertile window in a woman’s menstrual cycle?
The fertile window is the period during a womans menstrual cycle when she is most likely to conceive. It spans approximately five days before ovulation to one day after ovulation.
How can I track ovulation?
You can track ovulation by counting the days in your cycle, observing physical signs such as tender breasts, increased basal body temperature, or egg white-like cervical mucus. Alternatively, you can use an ovulation test kit from the pharmacy.
How often should couples have sex to conceive?
Couples trying to conceive should have sex every two days during the fertile window. If you are unsure of the fertile window timing, having sex every two to three days throughout the menstrual cycle can also increase your chances.
How does a woman’s age affect her fertility?
As women age, the number of available eggs decreases, and the chances of miscarriage and chromosomal abnormalities increase. Other factors that can impact fertility include weight and various medical conditions. Consulting fertility specialists at a fertility center can provide personalized guidance.
What happens after fertilization?
After fertilization, the egg and sperm combine to form an embryo. The embryo travels along the fallopian tube for 4-6 days before reaching the womb, where it implants itself into the thickened lining of the uterus, preparing for pregnancy.
What is the average length of a woman’s menstrual cycle?
On average, a womans menstrual cycle takes 28 days, although this can vary widely from woman to woman.
