The amount of sperm in a normal person may vary depending on the time of abstinence, generally 2 to 5 ml, and less than 1.5 ml or more than 8 ml is considered abnormal. There is a negative correlation between the amount of ejaculation and the frequency of ejaculation. If the amount of ejaculation is still less than 2ml for 5 to 7 days, it is considered as a reduction of semen; if it is not ejaculation, it is called aspermia. Seminal plasma is the medium for sperm activity and neutralizes the acidic secretions of the vagina so as not to affect sperm motility. The reduction in semen volume (insufficient seminal plasma) is not conducive to sperm entering the uterus and fallopian tubes through the vagina, affecting fertilization.

Clinical significance

Abnormal results:

1. The amount of ejaculation is negatively correlated with the frequency of ejaculation. If the amount of ejaculation is still less than 2ml for 5 to 7 days, it is considered as a reduction of semen; if it is not ejaculation, it is called aspermia. Seminal plasma is the medium for sperm activity and neutralizes the acidic secretions of the vagina so as not to affect sperm motility. The reduction in semen volume (insufficient seminal plasma) is not conducive to sperm entering the uterus and fallopian tubes through the vagina, affecting fertilization. Common in the prostate and seminal vesicles have lesions, especially tuberculous diseases, congenital hypoplasia or inflammatory discharge tube obstruction, semen retention has room for abnormal parts.

2. If the amount of ejaculation exceeds 8ml, the sperm is diluted, which is not conducive to fertility. This can be caused by the hypersecretion of the anterior pituitary gonadotropin, which leads to an increase in androgen levels, and can also be seen in those who have been abstinent for too long.
