I was going to make this a standard post in the main sub, but I figured that it would be better suited here, since I found that I had a lot more to say than I initially thought. The quoted text is from a post from the ever so pleasant r-femaledatingstrategy. Here, a woman makes the case that much of what is said about female fertility is a myth. The post and username will not be present in this article, though I may have an archive created at a later time if I am requested by those in charge here. I will be addressing this one section at a time:

Some of these highly emotional moids who don’t do fact checking because they only care about getting their anger out have the impression that women become infertile at 30.

She actually has a point. Women do not suddenly become infertile at 30 with no possibility of having kids anymore. However, there is a major issue she is completely missing. What does a woman who is a decade younger have that a woman in her 30s does not have? Time to spare in finding a quality man. A single 30+ woman is starting from square one at an age where she does not have any time to lose if she wants to find a man to be the father of her children, since a relationship where marriage is the goal is a huge investment. Most of these relationships have at least a year's worth of time for vetting each other for marriageability, with more time still for preparing for the wedding. Finally, we also must consider that most men would like to have at least somewhat of a honeymoon period before putting a bun in the oven, so the prospects of marrying a woman over 30 come with the implication that he is going to have a smaller window of time available before they become parents. This is not to denigrate parenthood, but rather that a man in this position would likely feel like he is being viewed as a utility rather than valued as a husband and father, since if he was valued more this type of woman should have sought him out earlier than when she had the luxury of time and options.

While the turn around time from the initial encounter to marriage might not seem like that long of a period based on what I say, this still does not account for the fact that the search for the man in mind is not so easily attained. It can take quite a bit of trial and error when it comes to searching for a quality long term partner, as there are many cases where there are more dead ends than green lights in the road to marriage. And I have yet to get started on the man's perspective in all of this. Given the current state of sexual morality, it is typical for a woman to acquire more sexual partners as she gets older, as well as baggage from the past that makes her less desirable as a partner for marriage. Older women who claim to "know what they want/know their worth" also tend to be more demanding for what they want in their next relationship while previously being less demanding and more sexually giving to previous partners. So with this inverse relationship to what they can offer versus what they demand, is it really any wonder that men in their 30s would see women in their 20s as a far more ideal prospect? All of these

They fail to realize that the correct age is around 50 and the reason why many older women struggle with pregnancy is because their partner is older as well. Sperm quality drops with age.

First of all, 50 is the absolute limit in most cases, where the chances of pregnancy are extremely low. According to a table here, a chart here, another chart here, and another chart here, the chances of conception do indeed drop significantly at 30. Yes, women can get pregnant after 30, but based on the the statistics, it certainly is much easier for women to get pregnant in their 20s compared to their 30s. Also, we cannot ignore the fact that she sees tries to blame men for older women not being able to get pregnant. Male fertility does drop with age as well, but according to this article, "Male fertility generally starts to decline around age 40–45 years when sperm quality decreases." Another article states: "Unlike the early fertility decline seen in women, a man’s decrease in sperm characteristics occurs much later. Sperm quality deteriorates somewhat as men get older, but it generally does not become a problem before a man is in his 60s." So it looks like the deflection of blame is a bit shortsighted, since it appears that women's age would be a bigger factor since the sperm quality is a factor later than a woman's chances of conceiving as she ages.

Testosterone starts to drop after 25, then even more after 30... etc. I‘ve seen a few guys in their early 20s who are already balding and looking old and unattractive.

Some sources here and here claim that low testosterone is not a guarantee of a man being infertile or does not directly cause it. I will not claim that I know this is completely sound, but I certainly welcome any information to the contrary. And again, we see the mention of balding, as if that has anything to do with a man's level of health (it's genetics ffs and has no bearing on a man's sperm quality, testosterone, or anything related to having children). I have seen male balding discussed in a different post in relation to male health, and I hope that this is the same woman that made that one as well, since we certainly are in no need of more women believing these falsehoods on top of the preexisting ones (I am simply do not care enough to search through posting history to verify this).

Now here’s the real reason why women want to have babies rather early: so that they see their kids grow up. Our reasons are selfless. Moids don’t care if they die when their "special" child is still young and needy bEcAUse I CaN hAve KiDs EveN wHeN I‘M oLd. It’s about them. The motivation is selfish, as always.

Being that this is more editorial than objective, I will not address this section with charts and statistics. First of all, women are not proving to want babies "rather early" based on increasing ages of marriage and first born children. I bring up marriage because I would argue that it is women who are the reason for marriages happening later more so than men. More and more women are delaying their search for a man to marry in favor of doing anything but demonstrate that they seriously want marriage (e.g. casual sex with bad boys, chasing a career to the point where finding a husband is of the lowest priority). This is assuming that they wait for marriage to have children, as we know that many single mothers out there did not wait. Given that single mothers are single mothers due to poor decisions, that would fly in the face of "selfless" reasons, as a selfless woman would not choose a bad man to get her pregnant. Therefore I disqualify single mothers as being selfless on those grounds. As for the women willfully delaying marriage, placing finding a marriageable man at the lowest priority would also not be classified as "selfless." For the few women that actually have a selfless mindset, they are the ones who are not wasting time by willfully avoiding the type of men who are husband material. If she is so concerned about the alleged "selfish" men, are the women who would choose to have these men father their children incapable of making a different choice? Unless she is talking about countries outside the Western world, there is not any forced marriages. Besides, most marriages do not have an age gap significant enough for the man to die before the children have become adults, so to judge these cases based on possible outliers is just jumping to conclusions. Also, wouldn't most men who are that old be far less interested in having kids at that point? As far as I see, this is just a straw man case to make men bad and women good.

I can accept ideas presented without sourcing data so as long as the reasoning itself is sound. But if I start seeing issues with claims being made, I am sure as hell going to investigate what is presented and see if it matches with the facts of the real world.

One more thing I should address. Another question regarding fertility is not simply whether or not a woman is able to get pregnant, but also how many children she is able to have. Starting out at 30+, she is far less likely to be able to have as many children as a woman in her 20s. Also, regarding women being able to get pregnant in their 40s, it is far more likely that she had children prior to her 40s rather than having her first child in her 40s, since women who have had children when younger get their fertility window pushed back. Remember this whenever someone brings up a case where a woman had children in her 40s, so you can know to ask how many previous children that woman had and determine if the "not all women" example can be rebutted as a false equivalency.
