Purpose of semen analysis in male fertility
The main purpose of a semen analysis is to assess fertility in men who, together with their partner, have had difficulty conceiving. This test is essential because it allows the identification of possible abnormalities in the quality of the semen that could hinder the fertilization process.
The results obtained from the semen analysis can influence the choice of fertility treatments. If significant deficiencies are detected in any of the parameters analysed, doctors can recommend a series of tactical approaches to improve the chances of conception.
The semen analysis can also be used to monitor assisted reproduction treatments. It is therefore a key tool not only for diagnosing problems, but also for monitoring the progress of the chosen treatment.
Differences between semen analysis, spermiogram and spermogram
There are terms that are often used interchangeably, but which can have different nuances. Below is a brief description of each:
- seminogram: It refers specifically to the analysis of the parameters that affect semen fertility, such as its concentration, mobility and morphology.
- spermiogram: This term is sometimes used as a synonym for seminogram, but generally emphasizes sperm count and its morphological characteristics.
- Spermogram: It is often used in a similar way to the above, although it may include a more general analysis of the semen sample that is not limited to male fertility.
The differences between these terms may depend on the context in which they are used. However, it is important for both doctors and patients to understand that, in essence, they are all related to the evaluation of semen and its quality.
Procedure for performing a semen analysis
The process of carrying out a semen analysis involves several steps that ensure the correct collection and analysis of the semen sample. These steps are essential to obtain accurate and reliable results.
Preparation prior to semen analysis
Proper preparation before sample collection is essential. Below are some recommendations to follow:
- Sexual Abstinence: Abstinence is advised for 2 to 7 days prior to collection. This period is crucial to obtain a more accurate sperm count, avoiding variations that may occur if collection is done after a short period without ejaculation.
- Avoid substance use: Alcohol and tobacco should be avoided in the days prior to the semen analysis, as they can affect semen quality.
- Medical consultations: If you are undergoing any medical treatment or have had any recent illness, it is advisable to consult with your doctor to assess the suitability of the analysis.
Collection and transportation of the semen sample
The way in which the semen sample is taken and transported influences the final results of the semen analysis. The procedures are as follows:
- Sampling: It is usually obtained through masturbation. It is important to collect the entire sample, as the first few drops usually contain the largest amount of sperm. Lubricants and condoms should not be used as they may contaminate the sample.
- Shipping cost: Once the sample has been obtained, it must be taken to the laboratory within a maximum of 30 minutes. It is advisable to keep the sample at body temperature, so it can be carried close to the body, wrapping it in aluminium foil to protect it from light.
Conditions for an accurate analysis
To ensure that the semen analysis is effective, there are certain conditions that must be met:
- Controlled environment: The sample must be analyzed in a specialized laboratory, where environmental factors that could affect semen quality can be controlled.
- Time between collection and analysis: It is preferable that the sample be analyzed as soon as possible after collection. This limited time helps minimize changes in semen quality.
- Sample preservation: During transport, the sample must be kept in optimal conditions, avoiding extreme temperatures or exposure to direct light.
Parameters analyzed in a semen analysis
The semen analysis examines various semen parameters that are essential for assessing male fertility. Each of these elements provides valuable information on semen quality and, therefore, on the ability to conceive.
Semen volume
The volume of the ejaculated semen sample is a key factor in the assessment of male reproductive health. A volume considered normal ranges from 1.5 to 6 milliliters. Lower values may suggest problems in the seminal glands, which could affect semen production and quality. An excessively high volume may also indicate certain abnormalities that deserve attention.
Semen pH
Semen pH is another crucial parameter, which should generally be between 7.2 and 8.1. A low pH below 7.2 can be a sign of infections or inflammation in the reproductive tract. On the other hand, a pH above 8.1 is not necessarily problematic, but its alteration can influence the dynamics of sperm and their ability to fertilize the egg.
sperm concentration
This parameter measures the number of sperm present per milliliter of semen. The World Health Organization considers a normal count to be 15 million sperm per milliliter. Situations such as oligozoospermia, which occurs when the concentration is lower than this figure, can be classified as:
- Moderate oligozoospermia: between 10 and 15 million/ml.
- Severe oligozoospermia: between 0.1 and 10 million/ml.
- Cryptozoospermia: less than 0.1 million/ml.
- Azoospermia: absence of sperm in the semen.
Sperm motility
Motility is a critical indicator of the sperm's ability to move efficiently toward the egg. It is classified into different categories:
- A class: Fast sperm with straight trajectories.
- Class B: Sperm with moderate speed and straight trajectories.
- Class C: Slow sperm, with limited movement.
- Class D: Immotile spermatozoa.
An adequate percentage of motile sperm is essential to increase the chances of conception, since their mobility allows them to reach the egg at the right time.
Progressive mobility
Progressive motility specifically refers to sperm that display rapid, straight-line movement. This type of motility is crucial for fertilization, and a good percentage of sperm in this category is a positive indicator of fertility.
Total mobility
Total motility includes all sperm that move, regardless of the quality of their movement. A high percentage in this parameter is desirable, as it reflects a greater ability of these sperm to reach the egg.
Sperm morphology
Morphology refers to the shape and structure of sperm. A percentage of more than 30% of sperm with adequate morphology is considered normal. Alterations in shape can affect the ability of sperm to penetrate the egg, affecting fertility rates.
Sperm vitality
Sperm vitality assesses the proportion of spermatozoa found alive in the sample. This parameter is significant, since the presence of dead spermatozoa can significantly compromise the chances of fertilization. A high percentage of live spermatozoa is expected to be a positive indicator of seminal health.

Semen analysis results and their interpretation
The results obtained from a semen analysis are essential for understanding male reproductive health. Below are the normal values, the most frequent anomalies and the impact that these results can have on fertility and natural pregnancy.
Normal values of spermiogram
The seminogram establishes reference values that are key in the evaluation of semen quality. These values allow the categorization of a man's reproductive health and may vary slightly according to clinical guidelines. Typical ranges include:
- Volume: between 1.5 and 6 milliliters per ejaculation.
- Sperm concentration: at least 15 million per milliliter.
- Motility: At least 40% of sperm must be motile.
- Morphology: more than 30% must have a normal shape.
- pH: A suitable range is between 7.2 and 8.1.
These parameters provide an overview of semen quality and help determine whether a patient has a chance of conceiving naturally.
Common abnormalities and their meaning
When semen analysis results indicate abnormalities, it is crucial to understand their meaning. The most common alterations include:
- Azoospermia: complete absence of sperm in the semen, which may be indicative of problems in testicular production or blockages in the seminal ducts.
- Oligozoospermia: low sperm count (less than 15 million/ml), which can make fertilization difficult.
- Asthenozoospermia: insufficient sperm mobility, affecting their ability to reach and fertilize the egg.
- Teratozoospermia: high percentage of sperm with abnormal morphology, which can interfere with the fertilization capacity.
Each of these abnormalities presents the possibility of requiring further evaluation and, depending on the case, specialized treatment. A single semen analysis may not give a complete picture of fertility, and additional analyses are generally recommended to corroborate the findings.
Impact on fertility and natural pregnancy
Semen analysis results are crucial in the assessment of male fertility and can influence the prognosis of a natural pregnancy. Semen quality is related to conception capacity, where parameters such as concentration and mobility are considered critical. A semen analysis showing significant abnormalities suggests that there is a higher risk of difficulty in achieving pregnancy, which can often lead to considering assisted reproduction options.
The impact of the results is profound. In cases of mild abnormalities, lifestyle improvement measures such as dietary or exercise changes can be applied. However, in more severe situations, such as azoospermia or severe Oligozoospermia, advanced treatments may be necessary, including techniques such as in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI).
Understanding the results and their interpretation allows physicians to formulate an appropriate plan to address fertility issues and increase the chances of achieving a successful pregnancy.
Semen analysis and assisted reproduction treatments
Semen analysis is essential to determine the best treatment options for male infertilityDepending on the results, various assisted reproduction techniques can be considered, offering solutions tailored to the needs of each couple.
Artificial insemination and other treatments
Artificial insemination is one of the most common options for treating fertility problems. This procedure involves introducing sperm directly into the woman's uterus, increasing the chances of fertilization.
There are two main types of artificial insemination:
- Intrauterine insemination (IUI): Sperm that has been previously selected and prepared in the laboratory are used. This method is appropriate when the cause of infertility is mild or moderate.
- Insemination with donor sperm: This option is used in cases of severe male infertility or when there are problems with sperm production. Sperm are selected from anonymous donors who meet certain health criteria.
Other treatments that may be considered, depending on the results of the semen analysis, include:
- In vitro fertilization (IVF)In this procedure, eggs are fertilized by sperm in a laboratory, and the resulting embryos are transferred to the uterus.
- Intracytoplasmic sperm injection (ICSI): In cases of low sperm concentration or morphological problems, a single sperm is injected directly into the egg to facilitate fertilization.
Options for male infertility
Semen analysis results can reveal a variety of problems that may have contributed to infertility. This may include a low sperm count, poor sperm motility, or problems with sperm morphology. Depending on these results, treatment options may vary:
- Antioxidant supplementation: It is suggested in cases of oxidative stress, which can affect semen quality.
- hormonal injections: These may be indicated if there are hormonal problems that affect sperm production.
- Surgery: In some cases, surgical procedures may be necessary to correct physical problems that are obstructing the production or transport of sperm.
Current trends in assisted reproduction
Research in the field of assisted reproduction continues to evolve. New techniques and improvements to existing procedures are being developed, allowing for better outcomes. Some of the current trends include:
- Improvements in sperm selection: Use of advanced technologies to select sperm with greater viability and fertilization potential.
- Personalization of treatments: Increasingly individualized approaches based on the genetic profile and general health of patients.
- Revolution in egg and sperm freezing: With the improvement in cryopreservation techniques, the options for those who wish to delay motherhood or fatherhood have increased.
