Premature ejaculation is one of the common sexual dysfunction in men which can have a negative impact on a fife of both a man and his partner. Research suggests that around 30% of men experience premature ejaculation at some point in their lives.
Premature ejaculation is defined as a medical problem in which ejaculation happens too quickly. This means a condition in which a man ejaculates much sooner during sexual intercourse than desired. Premature ejaculation is categorized into two types - primary premature ejaculation and secondary premature ejaculation.
- Primary ejaculation - It is also known as lifelong premature ejaculation. It is a type in which a man experiences this problem from the first sexual encounter and stays with a man throughout life.
- Secondary ejaculation - It is also known as acquired premature ejaculation. It is a type in which a man does not experience any problem with ejaculation for years but suddenly he begins to experience it. It can result from some medical condition such as diabetes, high blood pressure, and depression.
Premature ejaculation can have a significant impact on the quality of life. Sexual dysfunctions are associated with a wide range of difficulties, including difficulties in maintaining a healthy relationship. Studies have shown that men who suffer from premature ejaculation tend to have lower intimacy level as compared to those men who do not suffer from premature ejaculation. Lack of intimacy in between a couple significantly affect their relationship.
The process of ejaculation involves two phases, namely emission, and expulsion.
Emission is a phase in which seminal fluid is secreted from the prostate and seminal vessels. It also involves other functions such as the contraction of smooth muscles of the seminal tract from the epididymis to the prostate to transport the ejaculate, a closure of the bladder neck and the internal urethral sphincter, and the ejection of sperms into the posterior urethra.
Expulsion is another phase of ejaculation in which semen is forcefully advanced through the urethral meatus by rhythmic contractions of the pelvic floor muscles and the bulbospongiosus muscles.
Causes of premature ejaculation
Premature ejaculation can occur due to multiple causes. The cause of premature ejaculation can greatly vary from one person to another. Some of the causes of premature ejaculation are as follows:
1. Problems with neurotransmitters
The process of ejaculation is controlled by neurotransmitters, which are chemicals released by the nerve cells in the brain. The primary neurotransmitter that prevents ejaculation is known as serotonin. Serotonin signals the brain. Whenever the level of serotonin in the brain fluctuates, premature ejaculation may occur.
2. Psychological problems
Psychological problems such as stress and depression can also contribute to premature ejaculation. Several studies have shown that the mechanism for many men who suffer from premature ejaculation is associated with stress or depression. Stress can have a large number of effects on the human body as it affects almost all systems, including the reproductive system.
3. Metabolic disorders
Metabolic disorders like diabetes and obesity are associated with premature ejaculation. Diabetes is a chronic disease which is characterized by high blood sugar level in the bloodstream. Diabetes can occur due to insufficient insulin production, a problem with insulin usage or both. The uncontrolled sugar level in the blood is associated with impairment of nitric oxide metabolism and serotonergic activity, which contributes to premature ejaculation. Ejaculation largely depends on the autonomic nervous system.
Obesity which is characterized by the accumulation of excessive body fat is another metabolic disorder which acts as a risk factor for premature ejaculation. Multiple studies suggest that there are various mechanisms through which obesity contributes to premature ejaculation. One of the common mechanism is that obesity increases the blood pressure in the body, which in turn lead to an increase in blood pressure in the urethra, which results in premature ejaculation.
4. Thyroid disorders
The prevalence of thyroid disorder is high among people throughout the world. The thyroid is one of the most important glands in the human body which performs many important functions in the body. The primary function of thyroid gland is to produce hormones that primarily plays a role in metabolism, growth, and development. It produces two hormones - thyroxine and triiodothyronine. Primarily there are two types of thyroid disorders - hyperthyroidism and hypothyroidism.
Evidence suggests that hyperthyroidism is associated with premature ejaculation. Hyperthyroidism is a condition which occurs when the thyroid gland becomes overactive and produces hormones in excess. In one of the studies, it was observed that treatment of hyperthyroidism leads to an improvement in the patients suffering from premature ejaculation. Thus it can be said that there is a correlation between the hyperthyroidism and premature ejaculation.
