Fertility Is a Shared Medical Question
For many years, infertility was discussed primarily as a women’s health issue. Women often underwent repeated examinations, blood tests, treatments, and procedures before the male partner received a complete evaluation.
Modern reproductive medicine has changed this understanding. Male factors may be the main cause of infertility or may contribute together with female factors in a substantial proportion of couples. Fertility evaluation should therefore involve both partners from the beginning.
At Jinemed, male infertility has developed as part of a multidisciplinary model connecting reproductive medicine, urology, andrology, embryology, genetics, and the IVF laboratory. The objective is not simply to obtain any sperm cell for treatment. It is to understand the cause, identify conditions that may be treatable, protect the man’s wider health, and select the most appropriate reproductive pathway for the couple.
Male infertility is not a single diagnosis. It is a broad field that begins well beyond the numbers written on a semen analysis report.
More Than One Laboratory Result
Semen analysis is usually the first laboratory step in evaluating male fertility. It provides information about several characteristics, including:
- Semen volume
- Sperm concentration
- Total sperm count
- Motility
- Morphology
- Vitality when clinically relevant
- Additional findings such as white blood cells or abnormal liquefaction
These measurements are important, but they do not divide men neatly into “fertile” and “infertile” categories. Semen parameters can vary between samples because of fever, illness, medication, abstinence period, collection conditions, stress, laboratory methods, or normal biological fluctuation.
For this reason, an abnormal result may need to be repeated under appropriate conditions. The findings should be interpreted together with the couple’s reproductive history, the duration of infertility, previous pregnancies, medical and surgical history, physical examination, and the female partner’s evaluation.
A semen analysis is a starting point. It is not the whole diagnosis.
Understanding the Possible Causes
Male infertility can arise from difficulties in sperm production, transport, function, ejaculation, or sexual activity. In some cases, more than one factor is present.
Potential causes include:
- Varicocele
- Hormonal disorders
- Obstruction of the reproductive ducts
- Undescended testis or previous testicular surgery
- Genetic or chromosomal conditions
- Infections and inflammation
- Cancer or previous chemotherapy and radiotherapy
- Diabetes and other chronic diseases
- Certain medications
- Sexual or ejaculatory dysfunction
- Testicular injury or torsion
- Heat, toxins, smoking, anabolic steroids, and other lifestyle exposures
- Unexplained impairment of sperm production
Some causes can be treated directly. Others cannot be reversed but can be managed through assisted reproduction. A careful evaluation helps distinguish between these pathways.
It is also important to recognise that male infertility can sometimes be a sign of a broader health issue. Hormonal abnormalities, genetic findings, testicular disease, or metabolic conditions may require medical attention beyond fertility treatment itself.
The Role of the Urologist
When male-factor infertility is suspected, evaluation by a urologist or andrology specialist may be necessary.
The assessment may include a detailed reproductive and medical history, examination of the testes and reproductive tract, and evaluation for conditions such as varicocele, obstruction, testicular abnormalities, or hormonal signs.
Depending on the findings, additional investigations may include:
- Hormone tests such as FSH, LH, and testosterone
- Scrotal or reproductive tract ultrasound
- Repeat or specialised semen analysis
- Genetic testing in severe sperm-production disorders or azoospermia
- Assessment of sexual or ejaculatory function
- Evaluation before surgical sperm retrieval
Not every patient needs every test. The investigation should be guided by the history, physical examination, and initial semen results.
At Jinemed, the connection between urology and reproductive medicine allows the male partner’s evaluation to become part of the couple’s treatment plan rather than a separate process that delays care.
Azoospermia: Absence of Sperm in the Ejaculate
Azoospermia means that no sperm cells are identified in the ejaculated semen sample after appropriate laboratory examination. It does not automatically mean that the testes contain no sperm or that biological parenthood is impossible.
The first responsibility is to confirm the finding and investigate its cause.
Azoospermia is generally divided into two broad categories:
Obstructive Azoospermia
Sperm production may be present, but a blockage prevents sperm from reaching the ejaculate. Possible causes include congenital absence of reproductive ducts, previous infection, vasectomy, injury, or surgery.
Depending on the diagnosis, reconstruction may be considered in selected cases, or sperm may be retrieved directly from the epididymis or testis for use with IVF and ICSI.
Non-Obstructive Azoospermia
Sperm production within the testes is severely reduced or occurs only in small, scattered areas. Possible causes include genetic conditions, testicular failure, undescended testes, previous chemotherapy, or unexplained impairment of sperm production.
In selected patients, surgical exploration using techniques such as TESE or micro-TESE may identify small areas containing sperm. However, retrieval cannot be guaranteed. The likelihood of finding sperm depends on the underlying diagnosis and individual testicular function.
Distinguishing between obstructive and non-obstructive azoospermia is essential because the expected treatment, counselling, and sperm-retrieval strategy are different.
Genetic Evaluation in Severe Male Infertility
Severe oligospermia or azoospermia may sometimes be associated with chromosomal findings or changes involving genes important for sperm production.
Depending on the clinical situation, genetic evaluation may include chromosome analysis, Y-chromosome microdeletion testing, or testing related to congenital absence of the vas deferens.
Genetic counselling is important for several reasons. A result may help explain the cause of infertility, provide information about the likelihood of surgical sperm retrieval, identify wider health implications, or reveal a finding that could be passed to a child.
The purpose of genetic evaluation is not merely to complete a checklist before IVF. It is to help the patient understand the diagnosis and make informed reproductive decisions.
Treating Reversible Factors
Assisted reproduction is not always the first or only treatment.
When a specific, reversible cause is identified, the medical team may discuss direct treatment. Depending on the patient, this may include management of a clinically significant varicocele, treatment of an endocrine disorder, correction of an obstruction, treatment of infection when present, or support for sexual and ejaculatory dysfunction.
Medication must also be reviewed carefully. Testosterone injections, gels, anabolic steroids, and some performance-enhancing substances can suppress the hormonal signals that stimulate sperm production. A man may have a normal or high blood testosterone level while producing very few or no sperm cells.
Stopping or changing medication should take place under medical supervision. Recovery of sperm production can take time and is not identical in every patient.
Lifestyle factors also matter, particularly smoking, excessive alcohol use, obesity, heat exposure, poor sleep, and recreational drugs. Improving general health may support reproductive function, but lifestyle advice should not be presented as a guaranteed cure for severe male infertility.
The ICSI Milestone
The development of intracytoplasmic sperm injection, or ICSI, transformed the treatment of male-factor infertility.
In conventional IVF, many sperm cells are placed around an egg and fertilisation occurs when one sperm penetrates it. In ICSI, an embryologist selects a single sperm cell and injects it directly into a mature egg.
Jinemed became one of the early adopters of ICSI in Türkiye in 1995. This milestone expanded treatment possibilities for couples affected by very low sperm count, poor motility, severe morphology problems, previous fertilisation failure, or sperm obtained surgically from the epididymis or testis.
ICSI removed several barriers to fertilisation, but it did not eliminate the importance of male diagnosis. The presence of a sperm cell does not explain why sperm production is impaired, whether a genetic condition is involved, or whether the man has a treatable medical problem.
For Jinemed, ICSI became part of a broader male-infertility pathway rather than a replacement for proper evaluation.
Surgical Sperm Retrieval
When sperm cannot be obtained from the ejaculate, sperm may sometimes be retrieved directly from the male reproductive tract.
The appropriate technique depends on whether the problem is obstructive or related to sperm production. Procedures may include aspiration from the epididymis or testis, conventional TESE, or microdissection TESE in selected cases.
These procedures require close coordination:
- The urologist evaluates the diagnosis and performs the retrieval.
- The embryology laboratory examines the collected fluid or tissue for sperm.
- Suitable sperm may be used with ICSI or frozen when appropriate.
- The reproductive medicine team coordinates timing with the female partner’s IVF cycle.
Jinemed’s integration of TESE, ICSI, and embryology allowed complex male-factor cases to be managed through a coordinated clinical and laboratory system.
Surgical sperm retrieval should never be presented as certain to find sperm. Patients need realistic counselling about the expected chance of retrieval, possible need for tissue analysis, procedure-related risks, and the plan if no usable sperm is identified.
Sperm Freezing
Sperm cryopreservation can preserve an important future reproductive option.
It may be considered before chemotherapy, radiotherapy, testicular or reproductive surgery, or when sperm production may decline. It can also be used to secure a sample before an IVF cycle or preserve surgically retrieved sperm when sufficient material is available.
The sample is processed, divided into labelled storage units, frozen, and stored in liquid nitrogen. When needed, it is warmed and assessed for use with insemination, IVF, or ICSI depending on the number and quality of surviving sperm.
Not all sperm cells survive freezing and warming, and cryopreservation does not guarantee future pregnancy. Nevertheless, it may protect a possibility that would otherwise be lost, particularly when medical treatment must begin quickly.
Sperm DNA Fragmentation
Standard semen analysis evaluates concentration, movement, and appearance but does not directly measure the integrity of the DNA carried within sperm cells.
Sperm DNA fragmentation testing may be discussed in selected clinical situations, such as particular patterns of recurrent pregnancy loss, repeated treatment failure, significant risk factors, or unexplained findings after specialist evaluation.
However, it should not become a routine test offered to every man regardless of history. The interpretation of results, laboratory methods, and evidence for changing treatment can be complex.
A high result does not by itself identify the cause or automatically determine one treatment. A normal result does not guarantee fertility. The test is most useful when the medical team has a clear question and a plan for how the result may influence management.
Choosing the Appropriate Treatment Pathway
The treatment of male infertility depends on the cause, severity, duration of infertility, female partner’s age and ovarian reserve, previous pregnancies, and the couple’s priorities.
Possible pathways may include:
- Treatment of an identified medical or surgical cause
- Timed intercourse after appropriate evaluation
- Intrauterine insemination in suitable cases
- IVF
- IVF with ICSI
- Surgical sperm retrieval combined with ICSI
- Sperm freezing before medical treatment
- Genetic counselling and testing
The most advanced treatment is not automatically the most appropriate. A couple with a mild, potentially reversible male factor requires a different strategy from a couple facing non-obstructive azoospermia.
Good care begins by defining the problem before selecting the procedure.
International Male-Factor Patients
International patients with severe male infertility often need more preparation before travelling than standard IVF patients.
The medical file may need to include at least one properly performed semen analysis, hormone results, ultrasound or examination findings, previous TESE or pathology reports, genetic tests, cancer-treatment records, and details of prior IVF fertilisation.
In some cases, evaluation should be completed before the female partner begins ovarian stimulation. If surgical sperm retrieval is planned, the team must decide whether retrieval should occur in advance with freezing or be coordinated with egg collection.
Through Jinemed and IVF Turkey, the aim is to review these questions before travel so that the couple understands the clinical plan, possible alternatives, and what will happen if sperm retrieval is unsuccessful.
Complex male infertility should not be organised around flight dates alone. The biology and the medical diagnosis must determine the schedule.
A Shared Journey
Male infertility can affect identity, confidence, relationships, and emotional wellbeing. Some men experience shame or avoid evaluation because they associate fertility with masculinity.
This stigma can delay diagnosis and place an unnecessary physical and emotional burden on the female partner.
At Jinemed, the male partner is approached as a patient with his own medical history—not simply as the provider of a laboratory sample. Respectful communication and shared decision-making help couples understand that infertility is a medical condition, not a measure of personal worth.
The most effective treatment journey is one in which both partners are evaluated, informed, and supported.
Beyond the Semen Analysis
The history of male infertility care at Jinemed reflects the wider evolution of reproductive medicine: from basic semen testing to urologic evaluation, hormonal and genetic investigation, ICSI, TESE, sperm cryopreservation, and coordinated laboratory care.
Yet technology is only part of the story.
The central principle remains simple: first understand the man, then understand the sperm, and only then decide how treatment should proceed.
By bringing urology, reproductive medicine, embryology, and genetics together, Jinemed continues to treat male infertility as a complete medical field and an essential part of the couple’s shared fertility journey.
