Is erection in the morning due to holding back urine? Normal men get hard in the morning. This is generally called morning erection. Many people think that erection in the morning is due to holding back urine. So, is erection in the morning due to holding back urine? If there is a relationship between erection in the morning and the feeling of urination, then what is the actual relationship and what are the reasons for erection in the morning?

1. Having an erection in the morning is not due to holding back urine.
After men enter puberty and reach middle age, it is a normal physiological need to have an erection in the morning. Due to individual differences, the daily changes are also different, that is, the intensity, size, and duration of the erection are different. As long as the structure and function of the nerves, blood vessels, and cavernous bodies are normal, this phenomenon will occur, and it is not caused by urination resistance. Morning erections are caused by complex influences on the central nervous system and endocrine system, which mainly affect the blood vessels of the penis. When sexual desire is stimulated, information will be generated in the human brain and chemical information will be sent to the nerves responsible for controlling the blood vessels of the penis, promoting blood injection into the male genitals. Blood is trapped in the muscles of the male genitals, which causes the penis to become thicker and harder.

2. Reasons for morning erection
1. Drugs Anti-tumor drugs, anti-hypertensive drugs, hypoglycemic drugs, acid-suppressing drugs, sedative drugs and Chinese medicinal materials such as Anemarrhena and Phellodendron, etc., can reduce morning erections; while wild ginseng, skullcap, deer antler tablets and other drugs can improve morning erections.

2. Age. Under normal circumstances, age is the determining factor for morning erections. After estrus, as the age increases, the frequency of erections in the morning gradually becomes more frequent, and the duration also gradually increases. After the age of 30, as age increases, morning erections will gradually weaken or decline. However, some elderly people can still have a satisfactory married life although they do not have morning erections.
3. Sleep quality. Adequacy of sleep time and quality of sleep all affect androgen metabolism to varying degrees, which in turn affects morning erections.

4. Excessive emotional distress, depression, etc. can significantly reduce morning erections. Human life is too short, and happy days are too simple and clear, so why waste time on negative emotions.

5. Food ingredients: Donkey meat, fish, amaranth, wolfberry and other food ingredients can significantly enhance morning erections.
