Is it true that cats cause infertility?

Gosh, of course not!!!!  The only thing that you have to be careful of, and this is a very rare thing.  There is a parasite called toxoplasmosis that can be passed through a cats feces.  If you are pregnant, have someone else change the litter box.  Again, this is very very rare.  \nAs far a not getting pregnant because of your cat.....this is myth.

I am not aware of any studies on that, however logically I think that if you are fat, your menstrual cycles will tend to be anovulatory. Hence I would expect infertility rates to be higher in people who eat more calories per day (and do not compensate for it by exercising more).

Be careful, I heard of a married man that took viagra and his son had been away for a month.  When the son came back the mom was dead, the maid was pregnant and the younger sibling was running around holding his butt, and the cat was missing.  The son ended up suing the doctor.

Yes, but most often the baby is sterile and cannot reproduce.\nTiger and Lion- Liger\nDolphin and Whale- Wolphin\nHorse and Donkey- Mule

Many bats also delay implantation after the eggs are fertilized.  There are also several mammal groups that have delayed fertilization, holding viable sperm for months until they are ready to begin gestation, and then an egg cell is fertilized.\n\nThis is possible in placental mammals where the egg cell is kept internal, and doesn't have a shell to protect it from the outside environment.  I doubt that it would be possible in, for example, birds, where once the egg is formed it's pretty much a done deal, and development goes ahead regardless of outside conditions.

though, it can lead to infertility so you have to decide if you care about that...

It has to do with something call toxoplasmosis. You can get the disease after being in contact with cat feces. It can be treated and there is no much risk for the baby but if you are not pregnant yet, you can have a test before getting pregnant.

Pretty story, but genetically impossible.  Cats and dogs have a common ancestor, sure, but so do cats and people, and dogs and mice, and every single mammal that's around.  Cats and dogs belong to different taxonomical families - they have different chromosome nubers and different genes on different chromosomes that mean that no such thing as pittens or kuppies could be produced.  Yes, horses and donkeys can breed to produce a STERILE offspring - the mule or hinny, but that's because they're extremely closely related members of the equus family with very similar behaviour/courtship.  Cats and dogs aren't even that close.\n\nAnd puppies couldn't be born from implantation in a cat's womb - the DNA would be rejected by the mother as completely foreign.  Its being tried between camelids (alpacas/llamas etc) and an embryo doesn't implant even between these two very closely related species, so there's no way we can implant two such diverse species as a cat and dog, who are as closely related as a human and a lemur, or a horse and a rhinocerous.

It often occurs when the kitten in question is defective.  The mother needs nourishment, pregnancy is very draining, so a defective kitten which will die anyway, is only a drain on the mothers system.  It also occurs if the 'father' of the kittens realizes that any of the offspring are not his.  Finally, if there is not enough food available, if the conditions are not correct, or if the mother cat has had kittens removed from her before they should be, she realizes it makes no sense in raising them, so she will get rid of them.

Hye this is what I found from ROBERT ANDERSON, M.D.:\n"  Caffeine's effect on your sperm count depends on the health of your reproductive system. If you have a low sperm count, caffeine may increase your fertility. If your sperm count is normal, however, caffeine might decrease your chances of impregnating your partner. "\n\nSo there you have, but he later admits no real conclusive studies have been made, I would suggest to stay away from all energy drinks though, as they are banned in several countries, because not enough research has been done on the subject, and there have been problems with them.

Many kinds of cats, then some fish, and even wild pigs would do it on occasion.\n\nSome other species might simply kill their offspring, but not eat them. Sometimes this might happen when the ruling male knows he's not the father.

i had a cousin with PCOS and she has a beautiful 1 year old. They say that the biggest issue with PCOS is realizing that it is what causes your infertility. once you know what the problem is, you can find the right help to get pregnant.  you are probably more likely to miscarry more often, until you get pregnant (my cousin went through years of miscarriages before she had a successful pregnancy) and you will probably be high risk the whole time.

not penile dysfunction, but research has shown that some men may become less fertile (decreased sperm production)...but the big worry is that every time you smoke, the millions of brain cells that perish

NO...you cant get pregnant unless the sperm gets in your cutchie hole.

Fertility treatments that promote ovulation may lead to multiple births.

Women with polycystic ovarian syndrome often are infertile because they don't ovulate. 40% to 80% of women with PCOS have a problem with fertility. The reason for this wide variation is that PCOS is a complex metabolic syndrome, with multiple factors that can interfere with fertility. \n\nHaving PCOS does NOT mean you will not have children.  I would talk to your doctors about how to treat PCOS and increase your chance of having children.

Almost all males are infertile, but fertility in females is possible. About half of females are fertile. \n\nSo yes, it's possible, but it's not exactly common. More are infertile than fertile.\n\nIt's not really clear why most males are sterile, but I would suggest that the trisomy 21 condition (people with Down's syndrome have an extra 21st chromosome - in most cases, anyway) somehow interferes with the inactivation of the X chromosome in males, which leads to infertility.
