There is a famous saying: “Time waits for no man…”, and it’s true. Long before we give our first cry at birth, even before conception, our biological clock, in a way, had already run down and set a deadline.
Throughout our lives, our decisions, our habits, our technological advances and even our heritage can modify that finite time that was given to us, stretching it, or limiting it.
Biologically, aging is a multifactorial event where the sticky ends of our genetic material, known as telomeres, plus the accumulation of harmful oxidative species in our body, which alter the proper functioning of the body, stand out. Ultimately, the quality of our cells is diminished over time resulting in age-related diseases.
And although today, thanks to modern medicine, human life has been prolonged as never before in our history, there is a group of cells that time refuses to forgive: the oocytes.
Let us remember that each woman is born with a finite number of these cells. It is estimated that at birth each woman possesses about 2,000,000 oocytes, but when she reaches puberty that number decreases dramatically from 300,000 to 500,000.
The problem is that, in order to be fertilized, they must go through a maturation event and be released by the ovary only when sexual maturity is reached. During ovulation many of these oocytes are set in motion, but only the best of them are selected while the rest degenerate and are lost. This results in an average woman ovulating 400 to 500 oocytes over her lifetime.
This makes having children a race where the number of available eggs is not only limited, but also against the clock with each passing year where the quality of the oocytes decreases. This makes us ask the following question: what is the most fertile age for a woman, when is there a slight decrease and a marked decrease in female fertility?
Recent studies state that the most fertile age for women is 20-24 years old. At 25-29 there is a slight decrease in fertility, while at 35 and 39 there is a marked loss in the ability to conceive a pregnancy. Contact our specialists for more information.
