Penile retraction may be caused by obesity, lower temperature, emotional stress, older age and so on. 1. Obesity: If the body is too obese, the perineum and the root of the penis will have a thickened fat layer, resulting in the accumulation of fat, and the penis will be buried under the fat layer, resulting in the retraction of the penis. 2. Lower temperature: In the case of cold weather or lower temperature, penis retraction may also occur. 3. Emotional stress: If you are overly nervous, overly excited or frightened, it can lead to penile retraction. 4. Older age: As men grow older, the secretion of androgen in the body decreases. And insufficient congestion of the corpus cavernosum of the penis will cause the penis to start getting smaller. Penile retraction occurs. When penis retraction occurs, you should keep a good mindset and adopt healthy eating habits. If penile retraction is accompanied by discomfort, you should go to the hospital in time and follow the doctor’s instructions for treatment.
