Why are the eggs one big and one small?

Inconsistency in the size of male testicles is mostly a normal physiological phenomenon and may be caused by congenital developmental differences, varicocele, orchitis, epididymal cysts, trauma or surgical history and other factors.

1. Congenital developmental differences:

About 85% of men have testicular volume differences. Usually the right side is slightly larger than the left side. The difference within 1-2 ml is within the normal range. Developmental asymmetry may be caused by hormone levels or local pressure during testicular descent during the embryonic period. This difference will not affect reproductive function and sex hormone secretion and does not require special treatment.

2. Varicocele:

The left testicle is more prone to varicocele, with a prevalence of about 15%. Obstruction of venous return will lead to an increase in temperature and a reduction in the size of the affected testicle, which may be accompanied by a feeling of scrotal swelling. Mild cases can be alleviated by scrotal support, while moderate to severe cases require high ligation of the spermatic vein under a microscope.

3. Testicular inflammation:

Orchitis secondary to viral mumps can cause permanent testicular atrophy, and bacterial epididymo-orchitis can cause temporary enlargement. In the acute phase, the affected side is red, swollen, hot and painful, and antibiotics such as levofloxacin need to be used promptly. Chronic inflammation may leave behind fibrotic changes.

4. Epididymal cyst:

Cysts in the head of the epididymis are common and can be palpated to the size of a soybean, and can be diagnosed by B-ultrasound examination. Cyst resection is required when the cyst is large and creates a sense of pressure. Most small cysts do not require treatment. The disease may be related to vas deferens obstruction or inflammatory reaction.

3. History of trauma or surgery:

Scrotal trauma may cause testicular hematoma organization or atrophy, and inguinal hernia repair may damage the testicular blood supply. Patients who have had previous cryptorchidopexy may have testicular dysplasia. It is recommended to apply ice immediately after trauma and to regularly review testicular blood flow after surgery.

It is recommended to perform testicular self-examination every year. After bathing in warm water, hold the scrotum flatly with your hands to observe the morphological changes. Sudden obvious size differences or accompanying pain and induration require prompt medical treatment to rule out testicular torsion or tumors. Avoid wearing tight pants on a daily basis, and regular cold compresses are recommended for workers working in high-temperature environments. Pay attention to supplementing the diet with zinc, oysters, pumpkin seeds, vitamin E, nuts and spinach, and moderate exercise to improve pelvic blood circulation. Men over the age of 40 are recommended to have annual andrological ultrasound examinations.
