A donkey and a mule have different chromosome numbers. When meiosis occurs (the creation of egg and sperm) the chromosome numbers halve and half of the genetic material is given to each of the two new cells created. However in the case of mule, their normal body cells have an uneven chromosome number so this cannot occur, therefore they can't make eggs or sperm

Infertile is when you are unable to have children due to your body not function correctly. It is the opposite of being Fertile, which means you are able to or have the …physical capabilities of producing children.
There's no sure way of telling, unless you see a Doctor or fertility specialist.
A mule is the offspring of a male donkey and a female horse. They are known for their sure-footedness, as well as their ability to carry a heavy load and work with humans.… A cross breed between a male horse and female donkey is called a hinny. A hinny looks a bit more like a horse than a mule does. Female mules and female hinnys can rarely have offspring. The males can't ever reproduce, but they can mate.
A mule is a cross between a donkey stallion (called a jack) and a horse more.hinnies are just the opposite a stallion horse crossed to a donkey jennet .for all purposes hnnies… and mules are classified and shown together under the general term mule.
Medically, a couple is considered infertile if the woman is younger than 35 and who have had regular unprotected sex for 12 months or more without conceiving a child. For wome…n older than 35 years, the couple is considered infertile if they have not conceived a child of 6 months or more. A woman can be considered infertile if you have two or more times aborted pregnancies. Primary infertility is when the couple have never been conceived before, but refers to secondary infertility when couples have been successfully carried a child to term in the past.
They are a mix breed from horses and donkeys and horses and donkeys have different amount of chromosomes making conception difficult but in rare cases it has happend
The diploid number of a mule is 63. Mules have an odd number of chromosomes (63) - which means that the chromosomes do not pair off properly. This causes problems with meios…is, which is the process that creates the gametes (sex cells) that will be involved in sexual reproduction. This is why almost all mules are infertile. Mules are the result of a cross between two species. By definition, the offspring from two different species cannot be fertile. However, there are a few very rare cases of a female mule having a viable offspring.
Two mules can be a brace of mules if they are paired, haltered and equipped to work. If there are more than two animals, they will normally be termed a team.
There are several ways to figure out if you are fertile. First, if you are trying to get pregnant or trying to impregnate somebody - it should happen within the first 6 months… to a year of trying. If you are having trouble achieving a pregnancy, then you can try using Ovulation Tests, A Male Fertility Test or use a Fertility Monitor. You can also see your General Practioner for a referral to a Fertility Doctor.
All mammalian hybrids are sterile if male. The females can be subfertile.

No, mules are hybrids between two different species, and as such are considered sterile - they cannot reproduce. Male mules are always sterile. Female mules can very rarely… produce offspring, but this is so rare as to make headlines in veterinary literature. If mated to a male horse the offspring would be 75% horse. There is no name for these offspring because they are such an oddity.
Because mules are rarely fertile... Females might be, but males aren't.
Mules cannot reproduce. A mule is an offsprings of a horse and donkey and therefore are sterile.
They're beasts of burden. One thing they don't do, however, is have offspring. They sterile.
