When a semen sample measures less than 0.5 mL it is referred to as hypospermia. This abnormality can be the result of many different underlying factors such as hypogonadism, retrograde ejaculation, and obstruction of the lower urinary tract or a congenital bilateral absence of the vas deferens. It is also important to note that the first couple of drops of ejaculate typically have a high sperm concentration. Any incomplete sample or split ejaculates must be reported by the patient and should be documented in the analysis report. An incomplete sample can account for reduced semen volumes. Some patients do not produce an ejaculate after orgasm and instead produce dry ejaculate. This is more commonly referred to as aspermia. An accurate record of semen volume is essential. The laboratory may use a graduated serological pipette, a graduated 15 mL conical centrifuge tube or weight for accuracy. The WHO recommends using a preweighed sterile collection container for the most accurate volume [3].

In this study, there was a statistically significant difference between men with hypospermia and men with a normal semen volume regarding seminal Cd levels [(0.20 (0.18–0.25) µg/l) and 0.19 (0.16–0.22) µg/l, respectively (p = .049)]. In contrast, there was no statistically significant difference between two groups in terms of median seminal Pb levels. The values were 1.61 (1.44–1.77) µg/l in men with hypospermia and 1.52 (1.43–1.66) µg/l in men with normal seminal volume (p = .13).
Testicular protective effects of ellagic acid on monosodium glutamate-induced testicular structural alterations in male rats
Published in Ultrastructural Pathology, 2019
Reham Z. Hamza, Najah M. Al-Baqami
In this study MG caused several histopathological and ultrastructural changes, like spermatogenic arrest, edema, and hypospermia and, sometimes, azoospermia. These may be related to oxidative effects of MG on the testis cell membrane and testis tissues damage.
Decline in semen quality of North African men: a retrospective study of 20,958 sperm analyses of men from different North African countries tested in Tunisia over a period of 6 years (2013–2018)

Tunisian and Algerian men presented higher rates of hypospermia in 2015 and 2016 (Figure 3). Libyans presented a significant increase in hypospermia rate (2018 and 2015) and a significant decrease in sperm vitality rate in 2015 (Figure 3).
