What is Male Infertility – Causes of Infertility And Male Infertility tests

Infertility is emerging as a major problem even among young men these days. Most often a female is blamed for infertility. But the case can be different as well. Males-related infertility is responsible for almost 40% of infertility. In almost all cases Assisted Reproductive Technique is used for the treatment of all sorts of infertility. Let’s dive into the topic of what is male infertility and how you manage it.

Male infertility is a topic often shrouded in misconceptions and stigma, yet it affects countless individuals and couples around the world. Understanding the causes and diagnosis of male infertility is crucial for those navigating the challenging journey of starting a family. In this comprehensive guide, we delve into the intricacies of male infertility, exploring its various facets and shedding light on the diagnostic methods available. Whether you’re personally affected or seeking knowledge on the subject, this article is we will discuss symptoms, causes, tests, and treatment of male infertility.

Key Takeaways on Male Infertility:

Prevalence and Impact: Male infertility contributes significantly to overall infertility cases.

Sperm Health: Sperm count, motility, and morphology are crucial for fertility.

Reproductive System: Testicles and vas deferens play central roles in sperm production and transport. Diagnostic

Tool: Semen analysis is vital for assessing sperm health and diagnosing infertility.

Common Causes: Hormonal imbalances, genetic factors, and lifestyle choices contribute to male infertility.

Symptoms and Evaluation: Recognizing symptoms and a comprehensive evaluation aid in diagnosis.

Treatment Options: Assisted reproductive technologies, hormonal therapies, and lifestyle changes are viable treatments.

Lesser-Known Factors: Conditions like cystic fibrosis and erectile dysfunction can impact male fertility.

Male Infertility: An Overview

Male infertility is a condition where a man experiences difficulties in achieving conception with his female partner. Contrary to common misconceptions, infertility is not solely a female issue; it affects both genders, with male infertility contributing to 7-27 times the cases. Understanding the prevalence of male infertility is crucial, as it impacts couples worldwide who aspire to build a family.

The concern about male infertility arises from its significant role in the dynamics of reproduction. In heterosexual couples, approximately one-third of infertility cases are attributed to male factors. This emphasizes the importance of considering both partners when fertility issues arise.

Why should we be concerned about male infertility? The implications extend beyond the desire for biological children. Male infertility can be an indicator of underlying health issues, including hormonal imbalances and genetic conditions. Additionally, it can take a toll on the emotional well-being of individuals and strain relationships.

By addressing male infertility, we not only enhance the chances of conception but also promote overall reproductive and mental health.

Understanding Sperms and Fertility

Sperm, the microscopic agents of reproduction, play a pivotal role in fertility. The average ejaculate contains millions of sperm, each armed with the mission of fertilizing the egg. Male fertility is closely tied to the quality and quantity of sperm produced. Sperm count, a key metric in fertility assessment, is mentioned 25-46 times in relevant literature.

Sperm production is a complex process regulated by various factors, including hormonal signals from the pituitary gland. Hormonal imbalances, mentioned 1-2 times, can disrupt this delicate symphony, leading to decreased sperm production and fertility issues.

Understanding the factors affecting sperm production is crucial for diagnosing male infertility. Lifestyle choices, environmental factors, and genetic predispositions can all influence the health and viability of sperm. By unraveling the intricacies of sperm and fertility, individuals and healthcare professionals can better navigate the path to conception.

Behind the Numbers: Semen Analysis in Male Infertility

Semen analysis, mentioned 1-3 times, is a cornerstone in diagnosing male infertility. This diagnostic tool provides valuable insights into the health and functionality of sperm. During semen analysis, various parameters are assessed, including sperm count, motility, and morphology.

Sperm count, mentioned 1-5 times, refers to the number of sperm present in a given semen sample. Motility gauges the sperm’s ability to move effectively, while morphology evaluates the shape and structure of the sperm. Anomalies in any of these parameters can indicate potential fertility issues.

Interpreting the results of semen analysis requires a nuanced understanding of the factors influencing sperm health. Lifestyle choices, exposure to environmental toxins, and genetic predispositions can all impact the outcomes. A comprehensive analysis of semen provides a roadmap for addressing male infertility, guiding healthcare professionals toward appropriate interventions.

What can cause infertility in males?

So, what causes this infertility? Here are some of the medical, health, lifestyle, and environmental issues –

Medical Causes

• Varicocele–Varicocele is marked by testicular swelling in the veins. It is male infertility’s most reversible and common cause. The cause of the varicocele may be unclear, but it may be linked to testicular irregular temperature. Varicocele contributes to sperm count loss. Varicocele care and treatments can help to increase sperm count and function.
• Problems with ejaculation— Retrograde ejaculation happens when semen enters the bladder instead of the tip of the penis throughout orgasm. Different health conditions can cause retrograde ejaculations (, including diabetes, spinal injuries, medication, and bladder, prostate or urethra surgery. Ejaculatory duct obstruction is one of the causes of infertility in such men.
• Tumors— Cancers and non-malignant tumors may directly influence male reproductive organs by releasing reproductive hormones such as the pituitary gland or by unexplained causes. In some cases, surgery, radiation, or chemotherapy can affect male fertility in order to treat tumors.
• Hormonal Imbalances — Infertility can result from testicular disease or an abnormality affecting other hormonal structures, including the hypothalamus, thyroid, pituitary, and adrenal glands. There are several possible underlying causes of low testosterone (male hypogonadism) and other hormonal problems.
• Sexual intercourse issues — These may include erectile dysfunction problems, painful intercourse, hypospadias, or sex-interfering psychological problems.
• Celiac disease— Celiac disease is a gastrointestinal condition caused by gluten sensitivity that can lead to male infertility.
• Medicines–Long-term use of anabolic steroids, testosterone replacement therapy, cancer drugs (chemotherapy), certain ulcer drugs, certain antifungal drugs, and other medicines that impair sperm production and reduce male fertility.
• Infections— Some infections may interfere with the production of sperm or sperm. Such diseases may include epididymis inflammation or the testicles known as orchitis. The sperm can most often be removed, but in some cases, the infection leads to testicles being permanently damaged.
• Chromosome defects— Inherited diseases such as Klinefelter syndrome— where a male is born with two X chromosomes and one Y chromosome (rather than one X and one Y) — cause abnormal development of male reproductive bodies. Cystic fibrosis, the syndrome of Kartagener, and the syndrome of Kallmann are other infertility-related hereditary syndromes.
• Previous surgery — Some surgery can prevent you from ejaculating. Such procedures may include vasectomy, repairs to a hernia, prostate surgery, scrotal surgery, and large abdominal surgery.

Environmental Causes

• Exposure or X-rays- Long-term exposure to X-rays or any type of radiation leads to decreased sperm counts.
• Testicular overheating — Temperature rise will damage the production and function of sperm. Using the sauna bath regularly will affect your sperm count.
• Industrial chemicals — Long-term exposure to benzene, pesticides, herbicides, organic solvents, xylene, and paint products can result in low sperm counts.
• Heavy metal exposure — Exposure to lead and other heavy metals can contribute to male infertility.

Health and lifestyle causes

• Stress — Stress can interfere with the hormones required for sperm production. It can also contribute to male infertility as well.
•  Depression — If the male has severe depression, the risk of pregnancy is lower. It may be due to low libido, erectile dysfunction, or delayed ejaculation.
•  Weight— Being overweight can contribute to hormonal changes that may further reduce male infertility.
• Drug consumption— Drinking alcohol can lead to reduced levels of testosterone which can lead to a reduction in erectile function and sperm count. Liver disease caused by excessive drinking can also cause problems with infertility.
• Tobacco-smoking men have a lower fertility rate than non-smoking men. Passive smoking can harm male fertility as well.
• Drug use–Anabolic steroids are used to improve muscle power and development can contribute to testicular shrinkage and sperm reduction. Use cocaine or cannabis, the sperm count and performance may also decrease momentarily.

Medical Tests for male infertility

So, how to know that a male is infertile? We know the causes but how to decipher which cause has caused the problem? Here comes the list of the diagnostic tests that can determine the reason why the male is infertile –

• Semen Analyses– Semen analyzes the number, quality, and viability of a man’s sperm, also known as a sperm count test. Semen is the sperm-containing liquid that is produced during ejaculation (plus other sugar and protein substances). A semen analysis checks three major sperm health factors:

1. Shape of sperm

2. Movement of sperm

3. Number of sperm

Sperm counts also fluctuate significantly from one specimen to another. In most cases, to ensure accurate results, multiple semen analysis procedures are conducted over some time. If your sperm sample is fine, your doctor will probably suggest that your female partner be tested before further male infertility tests.

• Post-ejaculation urine analysis – Sperm in your urine may indicate that during ejaculation (retrograde ejaculation) your sperm travels back into the bladder instead of out your penis.
• Genetic tests – If the amount of sperm is extremely low, a genetic cause may exist. A blood test can show whether the Y chromosome has subtle changes — signs of genetic abnormality. Genetic testing may be required to treat specific syndromes that are congenital or inherited. DNA Sperm fragmentations are recommended in case of unexplained infertility.
• TESA or MESA – TESA and MESA are two testicular biopsy forms. There are also others as well. MESA: epididymis sperm aspiration by microsurgery. TESA: Testicular sperm collection by biopsy.
• Testicular biopsy – This test involves the extraction of specimens with a needle from the testis. If the testicular biopsy results show that sperm production is normal, your problem is likely caused by a blockage or other sperm transport problem.
• Transrectal ultrasound – In your rectum, a thin, lubricated wand. This allows your doctor to check your prostate and scan for semen-carrying pipe blockages
• Scrotal ultrasound – This experiment uses sound waves of high frequency to create images inside the body. A scrotal ultrasound can help your doctor see if the testicles and supporting structures have a varicocele or other problems.
• Hormone screening– Hormones released by the pituitary gland, hypothalamus, and testicles play a key role in the production of sperm and sexual growth. Abnormalities may also contribute to infertility in other hormonal or organ systems. A blood test tests testosterone levels and other hormones.
• Physical test – A complete physical test can give a hint of varicocele and other hormonal imbalance insights.

The Role of Medical Interventions

In vitro fertilization (IVF) and its effectiveness in cases of low sperm motility IVF is a widely used assisted reproductive technology that can overcome challenges posed by low sperm motility. This section explores how IVF works, its success rates, and considerations for couples considering this option.

Intracytoplasmic sperm injection (ICSI): A breakthrough in male infertility treatment ICSI is a specialized form of IVF designed to address male infertility, including low sperm motility. This segment provides an in-depth look at ICSI, its success rates, and the specific scenarios where it may be recommended.

Surgical interventions: Varicocele repair and its impact on sperm motility Varicocele, a condition characterized by swollen veins in the scrotum, can impact sperm motility. This section explores surgical interventions, such as varicocele repair.
