What Is Sperm Concentration?

A semen analysis test describes the presence and severity of male infertility. Its various parameters show the quantity and quality of sperm cells.

One of these parameters is sperm concentration.

Men often have low fertility levels because their sperm concentration is compromised. This article will discuss the reasons for low sperm concentration and potential measures to enhance it.

Sperm concentration is the density of sperm per unit volume. Your sperm cells are present in semen. The semen analysis test also measures your seminal volume. The average semen volume should be more than 2ml for a successful pregnancy.

The discussion of semen volume is critical because sperm concentration and semen volume determine your total sperm count.

Sperm Concentration And Male Fertility

The role of sperm concentration in male fertility is hardly linear. You may have a low sperm concentration in semen analysis test but conceive, or vice versa. It is why many experts agree that total sperm count is a better indicator of fertility.

The principle is that sperm concentration is not the only deciding factor. Alone it does not give a complete idea of sperm health. Even if the concentration of sperm is adequate in 1 mL of semen, the total sperm may not add up to a pregnancy. In contrast, many men achieve fertilization even with a low concentration of sperm.

It is probably due to other parameters like sperm motility, semen volume, total sperm count, etc. For instance, you have adequate sperm, but they are either not motile or structurally robust enough to cause pregnancy.

In short, there is considerable variability in the relationship between sperm concentration and male fertility. Nevertheless, it is crucial to keep it in a healthy range to assure fertilization. It is the bare minimum, and you may need to work more to regain other sperm parameters.

Normal Sperm Concentration For Pregnancy

The sperm concentration ranges typically between 15 million to 259 million.

Oligospermia is a sperm concentration less than 15 million per mL, while azoospermia refers to the complete absence of sperm cells.

The sperm concentration less than 15 million may create fertility challenges.

What Are The Causes of Sperm Concentration?

The sperm concentration can be low due to less production, incomplete transport, or sperm destruction.

The Faulty Spermatogenesis

The production of sperm cells is governed by hormonal factors and the performance of testes.

The function of testes disturbs due to:

  • Genetic disorders leading to small size testes
  • Undescended testes
  • High temperature due to prolonged sitting or tight clothes

The under-secretion of testosterone or other reproductive hormones also causes poor sperm formation and maturation. Inadequacies of the hypothalamus in your brain can be the reason behind hormonal imbalance. Weight gain and nutritional deficiencies also may play a role.

Stress also disturbs hormonal health because it increases the levels of cortisol in your body. Cortisol stops testosterone from exerting its effect and leads to poor spermatogenesis.

Sperm Outflow Obstruction

If your sperm cells do not travel from the testes to the urethral bulb, their concentration declines because it is where they mix with seminal fluid.

The hindrance in outflow is due to remnants of sexual infections. Many sexually transmitted diseases ascend in your reproductive tract. They cause blockage of tubular structures that bring sperm from the testes to the penis for ejaculation.

Retrograde ejaculation refers to the transport of sperm to the urinary bladder. An injury to the abdomen or pelvis can cause this phenomenon, which leads to low sperm concentration.

Sperm Death

Sperm cells need nutrition to survive. If your seminal fluid lacks necessary nutrients like zinc or fructose, they die before reaching the female reproductive tract. Seminal fluid often has harmful antibodies as well that kill sperm cells.

How Can I Save My Sperm?

You can guarantee sperm safety exactly like you secure your money- in a bank. Sperm concentration is not always in your control. The things you can control are:

  • Eating healthy
  • Performing exercise
  • Wearing loose-fitting garments
  • Wearing condoms to avoid sexually transmitted diseases
  • Avoiding stress to keep hormonal balance

However, you cannot control aging, which often declines the quantity of sperm. Stress is also tricky to manage and not always under your control. So, you may want a backup plan as well. Sperm freezing provides you with such assurance.

Take an in-home sperm analysis to look at your sperm parameters. If they are up to the mark, opt for sperm freezing service and take the stress off your mind.

Some sperm is lost and damaged during the transport, storage, freezing, and thawing process. The semen analysis reflects values at the time of the analysis, after transport and before freezing. These values will decrease throughout the freezing and thawing process. A semen analysis alone cannot be used to predict fertility.
