How would a tubal ligation or vasectomy influence meiosis in individuals who elected to have one of these operations

taurus [48]

Vasectomy and Tubal ligation are operations that have an effect on meiosis in individuals who have elected to have these operations in that it causes meiosis to stop.

A vasectomy or Tubal ligation are operations that are often performed as a method of birth control. A vasectomy is the male version of the operation and includes a procedure that negates the gametes or sex cells from reaching the sperm and being ejected from the body, thus preventing fertilization.

Tubal ligation is a similar process performed on women. The goal of this operation is the same as in the vasectomy, to stop the "egg cell" from being released and thus preventing it from being fertilized. Both procedures have been shown to cause meiotic arrest in individuals following the operation, In some cases, meiosis resumes after some time.
