In general, the size of the testicles does not directly affect health. However, some studies in animals suggest that testicle size may affect the amount of sperm that a male produces. For example, a 2011 study in sheep found that testicle size directly related to the production of both testosterone and sperm.
The average length of a testis or testicle is between 1.8 inches to 2 inches. Testicles lesser than 1.4 inches can be considered as small and they indicate low production of the male sex hormone testosterone.
Most men's testicles are about the same size, but it's common for one to be slightly bigger than the other. It's also common for one testicle to hang lower than the other. The testicles should feel smooth, without any lumps or bumps, and firm but not hard.
Testicle abnormalities
The size of your testicles isn't directly related to fertility, but unusually small and soft testes could be a sign that something's wrong with your reproductive system.
The causes of small testes are either congenital or acquired. Chromosomal abnormalities such as primary and secondary hypogonadism induce testicular underdevelopment [2]. Klinefelter syndrome is the most common cause of primary hypogonadism in men [2].
The majority of the time, sagging testicles are a normal part of the aging process. The testicles naturally sag, even at a young age, to protect the sperm inside and keep them viable. Anyone worried about saggy balls or other associated symptoms should contact a doctor for a diagnosis.
Normal adult testes are ovoid and measure approximately 3 cm (AP) x 2-4 cm (TR) x 3-5 cm (length), with a volume of 12.5-19 mL 2. However, the size of the testes decreases with age. From the mediastinum testis, several radiating septa extend into the testis forming 250-400 lobules.
Most adult males have two testicles, and each typically measures around 4 x 3 x 2 centimeters (cm). However, testicle size can vary. It is also common to have one testicle that is smaller than the other.
Age. Over time, the testes will likely begin to shrink. This is a natural process, as the body produces less testosterone or sperm after the peak reproductive years.
If your scrotum looks or feels like it's full of fluid on one or both sides, you may have a hydrocele. A hydrocele may be caused by inflammation or injury but it's not usually painful.
The tuberous bush cricket wrests the record for largest testes in relation to body weight from a tiny species of fruit fly, Drosophila bifurca, whose testes account for 10.6% of its bodyweight.
Calcifications: These are small structures in the testicle or along the main sperm pipeline (vas) can become hard, almost rock like. These are always painless and rarely need to be removed.
The smallest? A squash ball is just a little smaller than the golf ball. At the other end of the scale, the largest is the basketball.
There is no specific frequency with which a man should ejaculate. There is no solid evidence that failure to ejaculate causes health problems. However, ejaculating frequently can reduce the man's risk of getting prostate cancer. Ejacu-lation can be through having sex or masturbating a few times a day.
Ejaculating is a natural bodily function that can bring pleasure and release tension. Ejaculating daily is unlikely to cause any harm to men who are in good overall health, but excessive ejaculation can lead to temporary fatigue or discomfort in the genital area and may affect sperm count over time.
Some studies suggest that moderate ejaculation (2–4 times per week) is associated with a lower prostate cancer risk. However, ejaculating more often doesn't mean your cancer risk drops even more.
Testicular volume rapidly increases during puberty and peaks at age 30 years.
Similarly, testicular size in men with supplement intake on fewer than 60 days was 0.8 (95% CI, −0.2 to 1.9) mL larger and in men with fish oil supplement intake on 60 or more days was 1.5 (95% CI, 0.2 to 2.8) mL larger compared with men with no supplement intake (P for trend = . 007).
Balls drop after birth
After that they slowly get bigger and heavier during puberty. Lots of boys and men (with balls) think that balls just kinda 'drop' again overnight during their teenage years. Balls don't drop like that, it's a gradual process.
When you climax, it's normal for testicles to "ride up" into your body. In some males, an "overactive" cremaster muscle pulls one (or both) of the testicles all the way out of the scrotum up into the groin. This condition, called retractile testicle, may explain your experience.
