What you may not know about your fertility journey: from birth to puberty.

Updated: Jun 18, 2024

A poster of women with varying ages tittled “What you may not know about your fertility journey: from birth to puberty”.

Okay! Lets start with the basics before diving into the more integrate parts of this discussion.

As much as I love giving a background story before delving into any stated topic -as per the heading- I would like to skip that step and move right into the topic of the day 'what you may not know about your fertility journey', so back to basics.


The first point to note is that a woman's fertility journey starts from about 20 weeks after conception and by that -yes- I mean in the womb. At 20 weeks the female fetus has a fully formed reproductive system with her ovaries containing all the eggs for a life time. However, this remains dormant until she reaches puberty and all her secondary sexual characteristics starts to unfold, bringing me to my next point.


As stated and read in the earlier paragraph, a woman is born with her complete set of eggs contained in her ovaries, having the most amount - having up to 7 million eggs at 20 weeks-. At birth, this number drastically reduces to about 1 to 2 million and keeps reducing until it reaches approximately 400,000 eggs at puberty. Please note that this is just an approximation and may vary from individual to individual.



Now that that's out of the way, i'm sure you are wondering at this point -if you do not know already- what happened to all them eggs?!!

Lucky for you, I have the information you might need, just keep reading this article and absorb as much information as you need.


Although there is a dormancy in the activity of the reproductive system from birth up until puberty, about 10,000 eggs die - or rather, gets reabsorbed- each month until puberty. So lets do the maths - except you hate maths, then you are free to skip- lets say a baby was born with about 2 million eggs and puberty kicks in at 13, so that is 12 months per 13 years - multiply- giving you 156 months. Now assuming she looses exactly 10,000 eggs each month, we have 156 multiplied by 10,000 -easy math-, by the time you remove the product of these figures from the estimated 2 million she initially started with we have about 440,000 eggs left in her ovarian reserve -hope this makes sense-.



So now we are done with the basics and I hope its been so good so far. At this point we have viewed a woman's fertility journey from birth up till puberty, the next phase would be focused on the fertility journey from the initial period of puberty till a few years leading up to menopause - sounds fun right-.

So lets give a brief recap on what was written so far;

  • At 20 weeks the female fetus has a fully formed ovary containing all the eggs for a life time

  • The number of eggs drops from about 7 million at 20 weeks to a range of 400,000 to 500,000 eggs at puberty

  • This loss is due to the reabsorbtion or death of about 10,000 eggs per month
