  • It may seem unfair that girls get periods and boys don’t, but it’s because their bodies are different. Girls have reproductive organs which include a uterus, ovaries, fallopian tubes, cervix, and vagina. Boy’s have a penis, scrotum (sack), and testicles.

    For girls – every month, the lining of the uterus thickens and prepares for a fertilized egg. If the egg doesn’t become fertilized, the lining sheds and blood is released from the uterus. This is called a period.

    So, having a period means that you’ll likely be able to get pregnant. Guys have different reproductive organs, so they don’t have a period and therefore can’t get pregnant. Some guys may actually feel that this is unfair

    • Well, i Definetly don'twanna feel that, bt there's another question, pregnent women also bleed from vegina, why? And please be simple this time, i dont wanna be a doctor! 😁😁

    • ohhh man,, sure not coz she's pregnent ,,

  • Biology.
    Every month or so, the uterus lining gets thicker to prepare for a fertilized egg if the woman becomes pregnant. If the egg doesn't get fertilized, that lining is released from the body as blood through the vagina. This monthly process is called menstruation or a period.

    • Thanks! It was helpfull!

    • sure

  • In order to carry a baby, the uterus lines itself with substance that is primarily blood but also contains mucosal tissue. This lining is integral in supporting a fertilised egg and pregnancy. Once a month the lining is released along with the egg which is called a period in order to make room for a new lining and egg. Men don’t get them because they don’t have uteruses, carry babies or have egg cells.

    • So, if you're periods are close, you dont have sex so that the new baby shoud get a new egg 😀😀😀😅😄😉

    • Not really it doesn’t matter

    • I mean, if its bout a day and you gonna have it, and the egg gets fertilized, so, will it won't effect the baby?

  • Cause a period is the shedding of your uterus lining once an egg has past because a sperm cell hasn't fertilised it. And so because you are a guy with no uterus, there's nothing to shed so you're good to go

    • Yeah, makes me happy, and does it hurts?

    • For some girls more than others, all depends on your own body

    • How des it affects the mood of girls then?

  • Boys don’t ovulate. Would you really want to bleed for days every time you release a reproductive cell? If that was the case every guy over twelve would be bleeding from his penis for the rest of his life!

  • 😂 😂

  • Thats like asking why girls do not have morning woods. Oh dear...
    Its because your body doesn't need to get ready for a possbile pregnancy once a month.

    • Hahahha, you got picky?

  • Boys can't have babies. Girls can.

    • I know that part, 😅😅😅

    • And that is literally it. That's the reason why we have periods. So we can have babies.

    • If the egg doesn't get fertilized by a guy's sperm then you would get your period.

    • Show All
  • Because boys aren't fertile, don't have uteruses or eggs. Women are the child-baring of the two.

    • Fertility causes periods you mean, well, it doesn't stop even if tge women is pregnent, i mean whats its theory, my head hurts, wahhhh 😄😄😄

    • Yeah your period stops if you get pregnant.

    • Oh wow, thanks for your help...

  • because you don't have a uterus...

    • What does that have to do with periods?

    • that's the whole reason for periods... When our body is waiting for some sperm are uterine lining thickens as it waits to get pregnant. When it doesn't get pregnant at the end of the month the lining sheds and goes out of the vagina along with the egg that was waiting for some sperm

    • Well, it haopens even if you're pregnent, whyyy?

    • Show All
  • Fellas don't (mostly) have eggs, or a uterine wall to shed.

  • Because you don't a uterine lining you need to get rid of every damn month

    • Explain if you can, i dont have a vegina, sooo i dont get you 😅😅😅

    • You don't have a uterus that you need to shed every month to because you didn't get pregnant. The body prepares the uterus for a possible pregnancy then for what ever reason needs to reset that progress and do it again next month. A period is basically just the body getting rid of all the preparation it did

    • My god, mother nature is so great, every month a new egg and that's natural 😍😍😍

  • We don't ovulate, you do, that's the reason. On the other hand we produce semen all the time and have to release it eventually, and if we don't do it some random day we just find out the nature got rid of it for us during our sleep.
    In a very simple way, you have an egg a month, we have millions of little swimmers, both of us have to replace it for new ones from time to time

  • Boys actaully do they just don't bleed from thier privates cause boys don't need to get rid of eggs so most boys don't even notice it

  • Oh dear

    • 😩😩😩

  • You’re 21 and asking this?

    • So what, its not about age, coz m not a doctor or something, so i may ask to know...

  • Biology

  • Google it is a better place to ask it contains many information that hard to explain in short it just the way of female anatomy

  • Boys have no ovaries and no uterus.

  • because we produce the baby u guy don't need period because y'all don't produce anything but sperm to fertilisze the egg

    • Well, thats pretty easy for us like just drinking water and eating! How does it affects a girls life?

    • A lot mentally physically and it can take a lot out of us plus raising them

    • I was just talking about periods, nt the baby or abything!!!

    • Never took one, m a techno man, never been in bio...

    • It's never too late.

  • Because of evolutionarily selected maternal and menstrual functions of a woman in preservation of the species.

  • Didn't you attend biology class?

  • I'd be fucking horrified if I started pissing blood
