📊 A normal s***mogram provides essential information about male fertility. According to the World Health Organization (WHO), the reference values are:

✅ Volume: minimum 1.5 ml
✅ Concentration: at least 15 million s***m/ml
✅ Total number: over 39 million s***m/ej*****te
✅ Progressive motility: at least 32%
✅ Normal morphology: minimum 4% typical forms
✅ pH: between 7.2 - 8.0

🔬 These criteria are basic benchmarks for assessing fertility. Any deviation requires additional investigations.
👨‍⚕️ A s***mogram does not just provide numbers, but the overall picture of male reproductive health.

🧬 Male fertility is not constant throughout the day. Scientific studies have shown that s***m parameters can vary depending on the time of collection.

🔹 In the morning, testosterone levels are higher, which can influence both s***m production and motility. In addition, laboratory tests have shown that samples collected early in the day often have better quality.

🔹 Towards the evening, hormone levels gradually decrease, and this can be reflected in slight differences in s***m concentration and vitality.

📊 Even if the differences are not dramatic, for correct evaluations in fertility investigations, doctors recommend collecting the s***m sample between morning and noon.

👨‍⚕️ Attention to these details can make a difference in establishing an accurate diagnosis and choosing the right treatment.

🔬 Testicular cancer is the most common form of cancer in men between the ages of 15 and 35 and its impact on fertility is significant. Studies show that between 30% and 50% of the diagnosed patients present a reduction in s***m count or quality even before treatment begins.

📊 Chemotherapy and radiotherapy, although effective in eradicating cancer cells, can irreversibly affect s***matogenesis. Also, surgical intervention to remove the testicle (orchiectomy) can alter hormonal levels, indirectly influencing reproductive capacity.

💡 International medical associations recommend fertility assessment and, when possible, s***m collection and cryopreservation before starting oncological treatment. This measure offers the patient a real chance of becoming a parent in the future.

🩺 Early diagnosis and specialized medical counseling are essential for protecting both general health and fertility.

💧 Did you know that proper hydration can influence male fertility?

Water is not only essential for general health, but it has a direct role in supporting male reproductive function. Studies show that insufficient fluid intake can affect s***m quality, decreasing ej*****te volume, motility and even s***m concentration.

🔬 A study published in the journal "Andrology" (2020) indicated that men with an optimal level of hydration had significantly better seminal fluid quality compared to those who were dehydrated. Also, another study in the journal "Human Reproduction" confirmed that the oxidative stress caused by dehydration can damage s***m DNA

👉 What you can do:

- Drink at least 2 liters of water per day
- Avoid excessive consumption of coffee and alcohol (they have a diuretic effect)
- Monitor the color of your urine – if it is dark in color, it is a sign of dehydration

How does a single testicle affect a man's reproductive health?

Many men wonder if they can have a normal hormonal and fertile life with only one testicle. The answer is, in most cases, YES.

👉 A healthy testicle can produce enough testosterone to maintain libido, muscle mass, bone density, and other essential hormonal functions.
👉 In terms of fertility, a single testicle can produce enough s***m to allow the conception of a child, as long as there are no other associated conditions.
⚠️ However, it is important for men with a single testicle to have regular checkups, especially if the remaining testicle has been affected by trauma, surgery or by other medical problems.

MYTHS ABOUT HOW TO INFLUENCE THE S*X OF A BABY

Since ancient times, people have tried to "control" the s*x of their child through all kinds of scientifically unvalidated methods: certain s*xual positions, specific moments of intimate in*******se, special diets for the mother or even superstitions related to the phases of the moon. 🌙🥚

In reality, the s*x of the child is determined by the type of s***m that fertilizes the egg: X (female) or Y (male). This process is random and it cannot be influenced naturally by the methods mentioned above.

⛔️ Neither the s*xual position, nor the time of day, nor a specific diet can change this biological mechanism.

➡️The only methods with some proven influence are advanced medical procedures, used strictly for prophylactic purposes, such as avoiding the transmission of genetic diseases associated with a certain s*x.

It is important to inform ourselves correctly and not fall into the trap of myths passed down from generation to generation. 👨‍⚕️

🧬 What do type C s***matozoa mean in a s***mogram?

In a s***mogram, type C s***matozoa are non-progressive – that is, they can move their tail, but they cannot advance in a straight line. This type of mobility is considered low and, together with immobile s***matozoa (type D), it may indicate a decrease in male fertility.

📊 Classification of s***m motility:
- Type A: fast and progressive mobility – s***matozoa that move efficiently
- Type B: slow and progressive mobility – s***matozoa that move, but more slowly or irregularly
- Type C: non-progressive mobility – s***matozoa that move their tail, but do not advance
- Type D: immobile s***matozoa – without movement

🔍 Importance of classification
Mobility is essential for the s***matozoa to reach the egg. A high percentage of type C or D s***matozoa can signal problems in the s***m production at testicular level and it can reduce the chances of natural fertilization.
📌 A small number of type C s***m is normal, but when they are in the majority, a detailed andrological evaluation is indicated.

How long can s***m survive in a woman's body? 🧬
After ej*******on, s***m enter the va**na and can quickly migrate through the cervix to the fallopian tubes. Under ideal conditions, a s***m can survive in the female reproductive system for 3 to 5 days ⏳, if the environment is favorable (optimal cervical mucus level and appropriate pH ⚖️).

Fertility is highest during ovulation 🌸, when cervical mucus becomes more fluid and nourishing, facilitating s***m mobility and survival. Outside of this fertile window, s***m are exposed to a more acidic and less permissive environment ❌, which significantly reduces the lifespan of s***m, sometimes to just a few hours ⌛.

This survivability is an important factor in planning a pregnancy 🤰 or avoiding it, which is why it is essential to better understand how reproductive biology works 🔬.

🧬 Gut microflora and male fertility 🧫

The link between gut microflora and male reproductive health is well documented in the medical literature. Imbalances in gut flora (dysbiosis) can indirectly influence s***m quality and hormonal levels, through complex inflammatory and metabolic mechanisms.

📌 Studies show that certain gut bacteria can affect the HPG axis (hypothalamus-pituitary-gonadal), altering testosterone production and s***matogenesis. In addition, dysbiosis is associated with increased systemic oxidative stress – a major factor in s***m DNA degradation.

🔬 A study published in Frontiers in Endocrinology (2022) showed that men with poor s***m quality had significantly lower gut microbial diversity compared to fertile men. Other research suggests that probiotic supplementation could improve s***m motility and concentration.

💡 So, gut health doesn't stop at digestion - it can have a real impact on male fertility. A balanced diet, rich in fiber and low in ultra-processed foods can help maintain a healthy gut microflora.

The main types of erectile dysfunction

Erectile dysfunction does not just mean the complete inability to achieve an er****on. There are several forms, each with specific causes and treatments:

🔹 Short-term er****on – loss of er****on shortly after initiating s*xual in*******se, even before pe*******on
🔹 Absent er****on – complete lack of er****on, despite s*xual stimulation or desire
🔹 Intermittent er****on – sometimes occurs, sometimes not, without a clear pattern. This type is often associated with psychological factors
🔹 Normal nocturnal er****on, but absent during s*xual in*******se – it suggests a psychogenic rather than an organic cause

📊 It is estimated that over 50% of men between the ages of 40 and 70 experience some degree of erectile dysfunction at some point.

🔍 Correct investigation and personalized treatment can make a difference. Erectile dysfunction is a treatable condition.
