I now and again listen from individuals who need assist in gauging their possibilities or odds of conceiving the gender in their selection. Sometimes, they believe they’ve particular instances which can make their odds higher or worse for what they’re attempting to reach. One instance of those particular instances is the age of the father-to-be.
I heard from a girl who stated "I just married a man who is middle aged. He already has grown children from a previous marriage. We would like to conceive and we are expecting for a girl. , but I have heard that the older a man is, the more likely he is to have a girl. Is this true, why or why not? "
This isn’t the primary time I've been requested this query. This appears to be a kind of previous other halves stories that has simply sufficient medical advantage to make it appear plausible. The considering in the back of this is going one thing like this: since a person's sperm depend Declines as he ages and there may be some other previous other halves story which theorizes upper sperm depend favors boys small children, then the diminished sperm depend because of age will have to make a woman child extra in most cases via default.
So let's damage these types of theories and previous other halves stories down. First, let's have a look at the speculation guy's sperm depend Declines with age. This one is thought of as true. However, such declines are in most cases very slight. In truth, I'm positive everyone knows older males that father kids with none issues in any respect. It's by no means uncommon. In truth, whilst there comes some extent in a ladies's older lifestyles when she will now not have kids because of her age, the similar isn’t true of fellows.
But, accepting the truth that some males have a declining sperm counts with age, there’s no definitive medical foundation to mention evidently top sperm depend favors boy small children. The considering in the back of that is that as a result of boy sperm don’t are living for terribly lengthy however are quicker shifting than lady sperm, you’re going to have a greater likelihood of conceiving a boy with a person who has a better sperm depend since the quicker shifting boy sperm will make it to the egg extra briefly. But right here's what this idea does no longer take note. If a better sperm depend exists, there will likely be simply as many lady sperm combating for the egg. Sure, they’re slower than the lads, however the ratio of X to Y or boy to lady is similar for males with top or low sperm. And the result is in most cases a 50/50 likelihood of both gender. And, although the top sperm depend idea used to be true (which I've simply argued that it isn’t,) this isn’t assured that the other would even be true.
Because in step with this considering, a decrease sperm depend manner much less X and Y sperm to be had. But as with the above instance, the ratio would stay the similar the similar. And so the end result (50/50 odds) will have to additionally stay the similar. So my opinion is that no, an older guy would nonetheless have kind of the similar 50/50 likelihood of conceiving a woman or a boy as a more youthful guy. This is right whether or not he has a top or low sperm depend. Because not anything has modified with the ratio of the ones sperm. As lengthy as he has kind of the similar ratio of lady to boy generating sperm (which research have proven is the norm in males of every age) then (until you are making different adjustments) you continue to have kind of equivalent odds.
So what do I imply after I say "other changes?" Believe it or no longer, I imply adjustments to the girl or mom. The girl who wrote me would most probably have extra luck seeking to trade her personal PH than being concerned about her husband, who may no longer trade his ratios. Whether you get a woman or boy is dependent upon whether or not an Y (boy generating) or X (lady generating) sperm chromosome fertilizes the egg. You could make an X or lady much more likely via the girl having an acid PH, the couple conceiving previous in her cycle, and the use of shallow intervention positions. These issues would have extra affect on conceiving a woman than the daddy's age. If they sought after a boy, then the other could be true, (overdue intervention, an alkaline PH, and so on.) however the guy already had boys and sought after a woman this time.
