Never have a period your entire life?

I just wanted to know—what happens if a woman has never had a period in her entire life? Just wanted to know if it was possible?Never have a period your entire life?
Yes not having a period is possible if you have hypogonadism... it would most likely result in infertility and hormonal problems. Here is a definition i found:
Hypogonadism is a medical term for a defect of the reproductive system which results in lack of function of the gonads (ovaries or testes). The gonads have two functions: to produce hormones (testosterone, estradiol, antimullerian hormone, progesterone, inhibin B), activin and to produce gametes (eggs or sperm). Deficiency of sex hormones can result in defective primary or secondary sexual development, or withdrawal effects (e.g., premature menopause) in adults. Defective egg or sperm development results in infertility.
The term hypogonadism is usually applied to permanent rather than transient or reversible defects, and usually implies deficiency of reproductive hormones, with or without fertility defects. The term is less commonly used for infertility without hormone deficiency
it would have to be a very rare case. like a genetic mistake, born without ovaries and uterus for example which is very unlikely. otherwise it will always be there.
