A semen analysis (plural: semen analyses), also called seminogram or spermiogram, evaluates certain characteristics of a male's semen and the sperm contained therein. [1] [2] [3] It is done to help evaluate male fertility, whether for those seeking pregnancy or verifying the success of vasectomy. Depending on the measurement method, just a few ...
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 ...
Laboratory examination of seminal vesicle fluid requires a semen sample, e.g. for semen culture or semen analysis. Fructose levels provide a measure of seminal vesicle function and, if absent, bilateral agenesis or obstruction is suspected. [13] Imaging of the vesicles is provided by medical imaging; either by transrectal ultrasound, CT or MRI ...
Some researches shows gross measures of body strength suggest that females are approximately 50-60% as strong as males in the upper body, and 60-70% as strong in the lower body. [31] One study of muscle strength in the elbows and knees —in 45 and older males and females—found the strength of females to range from 42 to 63% of male strength ...
Pineapple may also have anticancer effects. A review of studies on the effects of bromelain found that this group of digestive enzymes, which can be found in pineapple, may be a cancer prevention ...
The acidity can also impact you in other ways, she notes: "Eating more pineapple than one's body can tolerate can lead to irritations in the mouth, tongue, esophagus and lining of the stomach."
A semen analysis typically measures the number of sperm per millilitre of ejaculate, and analyzes the morphology (shape) and motility (ability to swim forward) of the sperm (the typical ejaculate of a healthy, physically mature young adult male of reproductive age with no fertility-related problems usually contains 300–500 million spermatozoa ...
The semen in ejaculate contains sex cells called sperm. After intercourse, sperm travel to the egg through the female reproductive tract, typically causing fertilisation to occur in the fallopian tubes. Fertility testing for men involves semen testing and genetic testing, as other factors such as impotence are obvious.
