A Comprehensive Guide to Male Infertility: Diagnosis, Treatment Options, and Success Rates in Istanbul

What is Male Infertility?

Male infertility is a significant issue that affects many couples, resulting in both psychological and physiological challenges. Approximately one in seven couples struggles to conceive after one year or more of regular, unprotected intercourse. This article will explore the causes of male infertility, particularly in the context of IVF treatment in Istanbul.

Historically, infertility has often been attributed solely to women; however, male infertility is a considerable contributor, accounting for about 40-45% of cases in couples unable to conceive. The reasons behind male infertility can include low sperm production, abnormal sperm function, or blockages that prevent sperm from being released. In this article you will learn the various factors, such as diseases, injuries, chronic health issues, lifestyle choices, and environmental influences, those contribute to male infertility.

What are the Signs and Symptoms of Male Infertility?

Most men may not experience overt symptoms of infertility; instead, the primary indication is often their partner's difficulty in achieving pregnancy. However, certain underlying conditions can lead to noticeable symptoms, such as genetic disorders, hormonal imbalances, enlarged veins around the testicles, or other obstructive issues.

Common signs and symptoms may include:

• Sexual Function Issues: Difficulties in ejaculation, decreased libido, or challenges in maintaining an erection (erectile dysfunction).
• Testicular Discomfort: Pain, swelling, or lumps in the testicular area.
• Recurrent Respiratory Infections: Frequent respiratory illnesses.
• Anosmia: Loss of the sense of smell.
• Gynecomastia: Abnormal breast enlargement.
• Reduced Body Hair: Decrease in facial or body hair.
• Abnormal Chromosomal or Hormonal Indicators: Signs suggesting genetic issues.
• Low Sperm Count: Results showing fewer than 15 million sperm per milliliter or under 39 million total sperm in an ejaculate.

When to Seek Medical Help for Male Infertility?

Men should consult a doctor if they have been unable to conceive after a year of regular, unprotected intercourse or if they experience any of the following:

• Issues related to erection or ejaculation, diminished sexual drive, or other sexual function problems.
• Discomfort or swelling in the testicular area.
• A history of issues related to the testicles, prostate, or sexual function.
• Previous surgeries involving the groin, testicles, penis, or scrotum.
• The female partner is over 35 years of age.

What are the Key Conditions for Female Conception?

For a woman to conceive, several conditions must be met regarding male fertility:

Healthy Sperm Production: Proper development and maturation of male reproductive organs during puberty are essential. At least one testis must function correctly, producing sperm while testosterone and other hormones are secreted at normal levels.

Transport of Sperm: After production, sperm must be transported from the testes through thin tubular channels, mixing with seminal fluid for ejaculation.

Adequate Sperm Count: A low sperm count in semen reduces the likelihood of fertilizing the woman’s egg. A sperm count of fewer than 15 million per milliliter or under 39 million total sperm indicates a low sperm count.

Functional and Mobile Sperm: Sperm must be motile; if not, it may struggle to reach and fertilize the egg.

What are the Causes of Male Infertility?

The causes of male infertility can vary widely, influenced by multiple factors, including:

• Frequency and timing of sexual intercourse.
• Duration of infertility and the partner's fertility history.
• Childhood illnesses and developmental history.
• Existing medical conditions (e.g., diabetes, respiratory issues).
• Past surgeries and their implications.
• Medication use and allergies.
• Exposure to environmental and chemical toxins.
• Sexual history, including sexually transmitted diseases (STDs).
• Overall health status, including diet and exercise habits.
• Congenital abnormalities.

A comprehensive medical and reproductive history, including lifestyle factors and any hormonal treatments or drug use, is essential for diagnosing male infertility.

What are the Medical Causes of Male Infertility?

Several medical conditions can contribute to male infertility:

1. Varicocele: One of the most common causes, varicocele refers to enlarged veins within the scrotum, leading to decreased sperm production and quality.
2. Infections: Certain bacterial and viral infections can cause inflammation in the testes, affecting fertility.
3. Ejaculatory Issues: Conditions like retrograde ejaculation, where sperm enters the bladder instead of exiting through the penis, can impact fertility.
4. Sperm Antibodies: The immune system may mistakenly attack sperm, reducing their viability.
5. Tumors: Cancer or benign tumors can affect reproductive hormones or lead to infertility through treatment.
6. Undescended Testicles: Testes that do not descend properly during development can hinder sperm production and increase cancer risk.
7. Hormonal Disorders: Issues with the hypothalamus, pituitary gland, or testicles can impact testosterone and sperm production.
8. Blockages: Congenital or acquired obstructions in sperm transport channels can cause infertility.
9. Celiac Disease: Gluten sensitivity may affect fertility, often reversible with a gluten-free diet.
10. Chromosomal Abnormalities: Genetic disorders can impair normal reproductive functions.
11. Sexual Dysfunction: Issues related to achieving or maintaining an erection can affect fertility.
12. Environmental Factors: Exposure to toxins, radiation, or certain medications can reduce sperm production.
13. Medications: Some drugs, including anabolic steroids and certain cancer treatments, can impact fertility.
14. Previous Surgeries: Surgical procedures affecting the reproductive organs may result in fertility issues.

How is Male Infertility Diagnosed?

Diagnosing male infertility typically begins with a comprehensive history and physical examination, followed by a semen analysis. A thorough sexual history, family history of infertility, history of STDs (Sexulally Transmitted Diseases),medications, and lifestyle factors are crucial in the assessment. According to the World Health Organization, a semen analysis after a 3-5 day abstinence is considered normal if the sperm count exceeds 15 million per milliliter, with at least 50% motility and 4% normal morphology according to Kruger criteria.

When sperm count is low, achieving pregnancy naturally becomes challenging. Factors influencing spermatogenesis may result in conditions such as azoospermia (no sperm),oligospermia (low sperm count),asthenozoospermia (poor motility),or teratozoospermia (abnormal morphology). Genetic tests may also be performed for men with significant sperm issues, including chromosomal analysis and Y chromosome microdeletions.

What are the Treatment Options of Male Infertility?

The choice of treatment for male infertility depends on the underlying cause, the issues identified in the semen analysis, the severity of the problem, and whether sperm is present in the semen. If a treatable condition is identified, addressing that issue is crucial. However, many male fertility issues remain unexplained.

Treatment options for male infertility may include:

• Lifestyle Modifications: Adjusting diet and nutrition, incorporating antioxidant-rich foods, and avoiding harmful substances like alcohol, drugs, and excessive heat can enhance sperm health.
• Medical Treatments: Hormonal therapies may be used for men with hormonal imbalances impacting sperm production. Antioxidant supplements may improve sperm count and motility.
• Injectable Treatments: For men with hypogonadotropic hypogonadism, hormone injections may restore sperm production and enable natural conception or assist with IVF treatment.
• IUI (Intrauterine Insemination): This method involves concentrating sperm and placing it directly into the uterus, improving the chances of conception, especially in cases of low sperm count or motility.
• Assisted Reproductive Technologies: IVF (In Vitro Fertilization), ICSI (Intracytoplasmic Sperm Injection) and other advanced techniques may be used to aid couples struggling with infertility. Procedures like TESE (Testicular Sperm Extraction) and micro-TESE are employed when no sperm is found in the semen.

What are the Success Rates of IVF and IUI Treatments in Istanbul?

The success rates of IVF and IUI treatments vary based on numerous factors, including the specific protocols used, the woman’s age, and the underlying causes of infertility. In Istanbul, fertility clinics have a range of success rates. For IUI, the pregnancy rates can range from 6-10% without ovulation medications to 20-25% with gonadotropin injections. IVF success rates may also differ, typically averaging around 30-50%, depending on individual circumstances.

Couples facing infertility challenges should consult with a fertility specialist to explore the best treatment options tailored to their needs. IVF treatments in Istanbul offer advanced technology and expert care to help couples achieve their dream of parenthood.
