Ultrasound measured testicular volume in Nigerian adults: Relationship of the three formulae with height, body weight, body-surface area, and body-mass index

Relationship between Body Mass Index (BMI) and testicular and hormonal parameters of sexually active male greater cane rats (Thryonomys swinderianus)

“…Wikramanayake (1995) and Spyropoulos et al (2002) reported relationship between testicular volume and body weight while Sobowale and Akiwumi (1989) and Bahk et al (2010) reported no correlation. The recent account of Innocent et al (2016) however reported relationship between left testicular volume and body weight but no relationship between right testicular volume and body weight. The observation in the cane rat reported in this work is consistent with our previous findings (Adebayo et al, 2009).…”

Morphological peculiarities of the testes in 41–50-years-old men

“…Th e right testes were signifi cantly higher than the left (2.68±0.39 cm and 2.48±0.31 cm respectively, p<0.05). Figure 4 shows that the total volume of the right and left testes in 41-50-years-old men was 25.53±6.06 cm 3 . Th e right testes had larger volume than the left (27.31±6.44 cm 3 and 23.75±5.23 cm 3 respectively, p<0.05).…”

“…Figure 4 shows that the total volume of the right and left testes in 41-50-years-old men was 25.53±6.06 cm 3 . Th e right testes had larger volume than the left (27.31±6.44 cm 3 and 23.75±5.23 cm 3 respectively, p<0.05). Th e weight of both testes was 20.93±4.75 g. Th e weight of the right and the left testes diff ered statistically signifi cantly (21.87±4.98 g and 19.98±4.44 g respectively, p<0.05, Figure 5).…”

“…Scientists have off ered various formulas for determining the testicular volume: (a) for a prolate ellipsoid: volume = length × width × height × 0.52; (b) for a prolate spheroid: volume =length ×width 2 ×0.52; (c) the empiric formula of Lambert: volume = length × width × height × 0.71, and (d) volume = length × width × height × (π/6), and others [3,6,8,9,11]. Mbaeri with co-authors [8] determined that the most rigorous method for calculating of testis volume is the empiric formula of Lambert.…”

“…However, this method can be used only for dead patients or aft er orchiectomy. For live patients, scientists have established some formulas for determining of testicular volume [3,6,8,9].…”
