Pre-ejaculate (also known as pre-ejaculatory fluid, pre-seminal fluid or Cowper's fluid, and colloquially as pre-cum) is a clear, colorless, viscous fluid that is emitted from the urethra of the penis during sexual arousal and in general during sexual activity. It is similar in composition to semen but has distinct
When performing cryopreservation of semen, it is the sperm quality after reviving the sample that is of importance, because many sperm cells die in the process. To be of use in assisted reproductive technology , the sample should after thawing have more than 5 million motile sperm cells per ml with a good grade of mobility.
A 1992 World Health Organization report described normal human semen as having a volume of 2 mL or greater, pH of 7.2 to 8.0, sperm concentration of 20×10 6 spermatozoa/mL or more, sperm count of 40×10 6 spermatozoa per ejaculate or more, and motility of 50% or more with forward progression (categories a and b) of 25% or more with rapid ...
Sperm quantity and quality are the main parameters in semen quality, which is a measure of the ability of semen to accomplish fertilization. Thus, in humans, it is a measure of fertility in a man . The genetic quality of sperm, as well as its volume and motility, all typically decrease with age . [ 17 ]
Spermatocele is a fluid-filled cyst that develops in the epididymis. [3] The fluid is usually a clear or milky white color and may contain sperm. [4] Spermatoceles are typically filled with spermatozoa [5] and they can vary in size from several millimeters to many centimeters.
According to one preliminary study, the bulbourethral gland fluid might not contain any sperm, [10] whereas another study showed some men did leak sperm in potentially significant quantities (in a range from low counts up to 50 million sperm per ml) into the pre-ejaculatory fluid, [9] potentially leading to conception from the introduction of ...

Necrozoospermia – all sperm in the ejaculate are dead; Leucospermia – a high level of white blood cells in semen; Normozoospermia or normospermia – It is a result of semen analysis that shows normal values of all ejaculate parameters by WHO but still there are chances of being infertile.
