What you need to know about Male infertility?
Male infertility is the term that signifies the inability of a man’s sperm to fertilize an ovum. In this article, let’s understand the various facts involved in this condition.
What is male infertility?
Reproduction (or making a baby) is a natural process and experience for most couples. However, unfortunately there are certain couples who find it very difficult to conceive due to various factors. Male infertility is one such factor and we shall understand this in an elaborate manner further.
A man’s fertility usually depends on the quantity and quality of his sperm. If the count of sperm a man ejaculates is lower than normal or if the sperm are of very poor quality, it will be really difficult, and also impossible in some cases for the pregnancy to occur. This condition is diagnosed only when after thoroughly testing both the partners, reproductive problems (Male infertility) is diagnosed in the male.
Factors affecting Male infertility
Male fertility depends on three elements:
- Sufficient spermatozoa production and release from the testes.
- The sperm must have the ability to travel unobstructed through the seminal duct.
- The sperm should be able to reach the ovum properly without any delay.
- These elements if not met generally affect the fertility and lead to the fertility problems.
- These problems include
- Low sperm count: In scientific terms, this means less than 20 million sperm per milliliter. The “normal” sperm count is considered to be 200 million per ejaculation.
- Low sperm motility: This signifies lower than 50% of the sperm that have purposeful forward movement which occurs towards the ovum.
- Poor sperm morphology: This is actually less than 30% of the cases in which the sperm lacks normal form and shape.
How common is male infertility?
Infertility is a common and widespread problem that is addressed to in a positive way today. For about one in five infertile couples this condition possibly occurs solely in the male partner. It is estimated that one in 20 men is diagnosed with a certain kind of fertility problem with very low numbers of sperm in his ejaculate.
What are the symptoms of male infertility?
Many cases see no obvious signs of infertility. Intercourse, erections and ejaculation usually occur without any kind of difficulty. It is crucial to note that the quantity and appearance of the ejaculated semen generally appears normal to the naked eye and therefore Medical tests are needed to find out if a man is infertile.
What causes male infertility?
Male infertility is generally caused by problems that affect either sperm production or sperm transport. Through medical testing, the doctor might be capable of finding the root cause of the problem.
Approximately two-thirds of infertile men have an issue with making sperm in the testes. Either low numbers of sperm are made and/or the sperm that are made do not actually function properly.
Sperm transport issues are generally noticed in the ratio of about one in every five infertile men. This number includes men who desire to have more children after a vasectomy. Obstructions or Blockages in the tubes that lead the sperm away from the testes to the penis can possibly lead to a complete lack of sperm in the ejaculated semen.
Certain causes of infertility that are not that common encompasses sexual issues that determine whether semen is capable of entering the woman’s vagina for fertilisation to occur (one in 100 infertile couples), reduced levels of hormones produced by the pituitary gland that finally signals the testes to release it (one in 100 infertile men); and sperm antibodies (discovered in one in 16 infertile men). In most men sperm antibodies will not affect the probability of a pregnancy but in some men sperm antibodies does decrease fertility.
