Reduced erectile function. Loss of body hair. Less beard growth. Loss of lean muscle mass.
Testosterone home testing kits are widely available from several companies, including LetsGetChecked, Everlywell, and Progene. They use your blood or saliva to test your hormone levels. After taking the test, you'll send your sample to a laboratory for testing.
Causes of low testosterone levels
Conditions that may cause hypogonadism include: testicular injury or infection. chemotherapy or radiation cancer treatments. pituitary gland disease or other hormone disorders.
Age-specific middle tertile levels were 409-558 ng/dL for men 20-24 years old, 413-575 ng/dL for 25-29 years old, 359-498 ng/dL for 30-34 years old, 352-478 ng/dL for 35-39 years old, and 350-473 ng/dL for 40-44 years old.
Short index finger, more testosterone
An index finger that is relatively short compared to the ring finger indicates that one has been exposed to a lot of testosterone in utero, whereas a relatively long index finger suggests a lower exposure to testosterone in the womb.
There are many symptoms of low testosterone in men, including flagging energy levels, low libido, weight gain, and hair loss. If you are experiencing any of these symptoms, consider getting your testosterone levels tested.
Living with a testosterone deficiency long-term will increase your likelihood of developing age-related diseases, including osteoporosis and heart disease, among others.
Finger length ratio (2D:4D) is a sexually dimorphic trait. Men have relatively shorter second digits (index fingers) than fourth digits (ring fingers). Smaller, more masculine, digit ratios are thought to be associated with either higher prenatal testosterone levels or greater sensitivity to androgens, or both.
Previous research has found that this "2D:4D" ratio — the ratio of the length of the second digit (the index finger) to that of the fourth digit (the ring finger) — reveals the amount of male hormones, mainly testosterone, a person is exposed to in the womb. The more testosterone, the longer the ring finger grows.
We show that total testosterone peaks [mean (2.5–97.5 percentile)] at 15.4 (7.2–31.1) nmol/L at an average age of 19 years, and falls in the average case [mean (2.5–97.5 percentile)] to 13.0 (6.6–25.3) nmol/L by age 40 years, but we find no evidence for a further fall in mean total testosterone with increasing age ...
This sex hormone usually peaks in adolescence and early adulthood. As men age, the ability to produce testosterone begins to decline such that testosterone levels begin to drop about 1 to 3 percent a year beginning around age 40 years.
Testosterone exhibits diurnal variation, peaking in the morning (between 8-10 am) with a nadir in the evening (about 8 pm).
Bananas can boost testosterone as well as improve energy levels. Other beneficial fruits include watermelon and grapes. Citrus fruits can help testosterone production and reduce the hormones that make testosterone production less effective.
Resistance training, such as weightlifting, has been shown to boost testosterone levels in the short term ( 13 ). High intensity interval training (HIIT) can be very effective as well, although all types of exercise should work to some extent ( 14 , 15).
Sorry boys, but it does seem the size of your fingers is a pretty good guide to your manhood. Long regarded as a myth and source of much amusement, scientists have now confirmed that the length of a man's index finger relative to his ring finger can reveal his penis size.
Signs and symptoms of high testosterone in men
Excess testosterone can lead to more aggressive and irritable behavior, more acne and oily skin, even worse sleep apnea (if you already have it), and an increase in muscle mass.
It turns out, whether you have a longer index or ring finger means a lot. Research suggests that having a longer ring finger compared to index finger reflects greater exposure to male hormones during an individual's time in their mother's womb.
Testosterone replacement therapy, in the form of injections, pellets, patches or gels, can improve the signs and symptoms of low testosterone in these men.
