Sperm are male reproductive cells present in the ejaculate. A doctor can tell someone their sperm count using a test called semen analysis. The average sperm count is between 40 million and million sperm per milliliter. This number can vary between testing centers, with the above range coming from Resolve , a nonprofit fertility association. A doctor may recommend a semen analysis for many reasons, such as to test for possible underlying causes of infertility , how well the reproductive organs are working, or whether a surgical procedure for sterility was successful.

What Is a Normal Sperm Count?

Normal Sperm Count: Understanding Your Semen Analysis

Semen analysis as an integral part of infertility investigations is taken as a surrogate measure for male fecundity in clinical andrology, male fertility, and pregnancy risk assessments. Clearly, laboratory seminology is still very much in its infancy. In as much as the creation of a conventional semen profile will always represent the foundations of male fertility evaluation, the 5th edition of the World Health Organization WHO manual is a definitive statement on how such assessments should be carried out and how the quality should be controlled. A major advance in this new edition of the WHO manual, resolving the most salient critique of previous editions, is the development of the first well-defined reference ranges for semen analysis based on the analysis of over recent fathers. The methodology used in the assessment of the usual variables in semen analysis is described, as are many of the less common, but very valuable, sperm function tests.

Sperm Motility

Sperm is the male gamete , that is, the male sex cell , or the cell in males which has the capacity to fertilise an egg i. Sperm are produced in the seminiferous tubes of the testes. The pituitary gland at the base of the brain causes testosterone to be produced in the testes. Testerosterone causes sperms to be produced.
Male infertility is often caused by low sperm count, abnormal sperm movement, or weak sperm. If you and your partner are trying to conceive, the results of this test can help you figure out the next steps you may want to take. You may also need this test if you've recently had a vasectomy. A vasectomy prevents pregnancy by keeping sperm separate from semen during ejaculation. Your healthcare provider can use this test to find out whether the vasectomy was successful.
