The sample should never be obtained through coitus interruptus for several reasons:

Some part of ejaculation could be lost. Bacterial contamination could happen. The acid vaginal pH could be deleterious for sperm motility.Also is very important to label the sample correctly the recipient with patient identification, date, hour, abstinence days, among other data required to be known. The volume of the semen sample (must be more than 1.5 ml), approximate number of total sperm cells, sperm motility/forward progression, and % of sperm with normal morphology are measured. It is possible to have hyperspermia (high volume more than 6 ml) or Hypospermia (low volume less than 0.5 ml). This is the most common type of fertility testing. Semen deficiencies are often labeled as follows:

Oligospermia or oligozoospermia – decreased number of spermatozoa in semen
Aspermia – complete lack of semen
Hypospermia – reduced seminal volume
Azoospermia – absence of sperm cells in semen
Teratospermia – increase in sperm with abnormal morphology
Asthenozoospermia – reduced sperm motility
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. This is also called as unexplained InfertilityThere are various combinations of these as well, e.g. Teratoasthenozoospermia, which is reduced sperm morphology and motility. Low sperm counts are often associated with decreased sperm motility and increased abnormal morphology, thus the terms "oligoasthenoteratozoospermia" or "oligospermia" can be used as a catch-all.
Those identifying as African American have been found to have a greater acceptance of larger body image ideals and less internalization of the thin ideal, and African American women have reported the lowest levels of body dissatisfaction among the five major racial/ethnic groups in the US.However, recent research contradicts these findings, indicating that African American women may exhibit levels of body dissatisfaction comparable to other racial/ethnic minority groups. In this way, just because those who identify as African American may not internalize the thin ideal as strongly as other racial and ethnic groups, it does not mean that they do not hold other appearance ideals that may promote body shape concerns. Similarly, recent research shows that African Americans exhibit rates of disordered eating that are similar to  or even higher than their white counterparts. American Indian and Alaska Native
American Indian and Alaska Native women are more likely than white women to both experience a fear of losing control over their eating and to abuse laxatives and diuretics for weight control purposes. They have comparable rates of binge eating and other disordered weight control behaviors in comparison to other racial groups. Latinos
Disproportionately high rates of disordered eating and body dissatisfaction have been found in Hispanics in comparison to other racial and ethnic groups. Studies have found significantly more laxative use  in those identifying as Hispanic in comparison to non-Hispanic white counterparts. Specifically, those identifying as Hispanic may be at heightened risk of engaging in binge eating and bingeing/purging behaviors.
