Understanding the Biological Clock: How Age Affects Fertility in Men & Women
The concept of the “biological clock” often evokes concerns about fertility, particularly as individuals grow older. While age is widely recognized as a critical factor in female fertility, it also plays a significant role in male fertility. Understanding how age affects fertility in both men and women can help individuals make informed decisions about family planning and seek appropriate medical advice when necessary.
How Age Affects Female Fertility
Female fertility is closely linked to age, primarily because women are born with a finite number of eggs. As a woman ages, both the quantity and quality of her eggs diminish, leading to a natural decline in fertility.
- Egg Quantity and Quality:
- Women are born with approximately 1 to 2 million eggs, but this number decreases over time. By puberty, only about 300,000 eggs remain, and this number continues to decline throughout a woman’s reproductive years.
- As a woman approaches her mid-30s, the decline in egg quality accelerates, and the chances of chromosomal abnormalities in eggs increase. This can lead to difficulties in conceiving, a higher risk of miscarriage, and a greater likelihood of genetic conditions such as Down syndrome.
- Menstrual Cycle Changes:
- The regularity of the menstrual cycle can also change with age. Ovulation may become less frequent, and periods may become shorter, longer, or more irregular. These changes can further reduce the chances of conception.
- Increased Risk of Complications:
- Women who conceive later in life face a higher risk of pregnancy complications, such as gestational diabetes, preeclampsia, and preterm birth. The likelihood of requiring fertility treatments, such as in vitro fertilisation (IVF), also increases with age.
How Age Affects Male Fertility
While male fertility does not decline as sharply as female fertility, age still plays a role in a man’s ability to conceive. Unlike women, men produce new sperm throughout their lives, but the quality and quantity of sperm decrease with age.
- Sperm Quality and Quantity:
- As men age, the production of sperm may decrease, and the sperm produced may be less motile and have more DNA damage. This decline typically begins around the age of 40 and can result in lower fertility rates.
- Older men are also more likely to produce sperm with genetic mutations, which can increase the risk of miscarriages and contribute to genetic conditions in offspring.
- Hormonal Changes:
- Testosterone levels naturally decline with age, which can affect sperm production and sexual function. Lower testosterone levels can lead to reduced libido, erectile dysfunction, and a decrease in overall reproductive health.
- Increased Risk of Genetic Disorders:
- Advanced paternal age has been linked to an increased risk of certain genetic disorders, such as autism and schizophrenia, in offspring. While the overall risk remains low, it is still a consideration for men who plan to father children later in life.
The Importance of Early Planning and Medical Guidance
Given the impact of age on fertility, early planning and proactive measures are essential for those who wish to have children. Here are some steps individuals and couples can take:
- Fertility Assessment:
- Both men and women can benefit from a fertility assessment, which may include hormone tests, ovarian reserve testing for women, and semen analysis for men. These tests can provide valuable insights into reproductive health and help guide family planning decisions.
- Lifestyle Modifications:
- Maintaining a healthy lifestyle, including a balanced diet, regular exercise, and avoiding smoking and excessive alcohol consumption, can help preserve fertility. Managing stress and getting adequate sleep are also important for reproductive health.
- Fertility Preservation:
- For those who are not ready to conceive but want to preserve their fertility, options such as egg freezing and sperm banking are available. These techniques allow individuals to store their gametes for future use, increasing the chances of successful conception later in life.
- Seeking Expert Advice:
- Consulting with a fertility specialist can provide personalised guidance based on individual circumstances. At Feminova Clinics, Dr. Chinmayee Sukhavasi and her team offer comprehensive fertility evaluations and treatments tailored to each patient’s needs.
In Conclusion,
Understanding the biological clock and its impact on fertility is crucial for anyone considering parenthood. While age affects fertility in both men and women, early planning, lifestyle choices, and medical interventions can help overcome some of the challenges associated with ageing. By seeking expert advice and taking proactive steps, individuals and couples can make informed decisions about their reproductive future.

How does age affect female fertility?
Female fertility declines with age due to a decrease in both the quantity and quality of eggs. This decline becomes more significant after the age of 35, leading to reduced chances of conception and a higher risk of complications.
At what age does male fertility start to decline?
Male fertility typically begins to decline around the age of 40, with decreases in sperm quality and quantity, as well as an increased risk of genetic mutations in sperm.
Can lifestyle changes help preserve fertility as you age?
Yes, maintaining a healthy lifestyle, including a balanced diet, regular exercise, and avoiding harmful habits like smoking, can help preserve fertility in both men and women.
What fertility preservation options are available for those not ready to conceive?
Options like egg freezing and sperm banking allow individuals to store their gametes for future use, helping to preserve fertility as they age.
