Exercise 49

Follow-up testing for a low sperm concentration would include testing for:

A. Antisperm antibodies

B. Seminal fluid fructose

C. Sperm vitality

D. Prostatic acid phosphatase

Step 1 of 2

Seminal fluid fructose:

The fructose is present in the seminal vesicles.

• Reduction of support medium in the seminal vesicles causes low sperm concentration.

• This indicates that the level of fructose absent in the semen is very low.

The reasons for low fructose level are as follows:

• Deformities of the seminal vesicles.

• Absence of bilateral congenital in vas deferens.

• Unfinished backward ejaculation.

• Insufficiency of androgen.

Presence of fructose in semen is detected by resorcinol test.

Therefore, after the low sperm concentration, the follow up test is “seminal fluid fructose”. Hence, the correct answer is option.
