Sperm motility describes the ability of sperm to move properly through the female reproductive tract (internal fertilization) or through water (external fertilization) to reach the egg. Sperm motility can also be thought of as the quality , which is a factor in successful conception ; sperm that do not "swim" properly will not reach the egg in ...
In some cultures, including Botswana [70] and Nigeria, [63] women can select a woman with whom she allows her husband to sleep with in hopes of conceiving a child. [63] Women who are desperate for children may compromise with her husband to select a woman and accept duties of taking care of the children to feel accepted and useful in society. [70]
The presence of abnormally-shaped sperm can negatively affect fertility by preventing transport through the cervix and/or preventing sperm from adhering to the ovum. Achieving a pregnancy may be difficult. [3] In testing for teratozoospermia, sperm are collected, stained and analyzed under a microscope to detect abnormalities.
Collecting the sperm at home gives a higher sperm concentration, sperm count and motility, particularly if the sperm is collected via sexual intercourse. [35] If the semen sample is to be collected by masturbation, a specimen from the early stages of the ejaculate should be into a clean, unused, sealed collection cup.
In both men and women, ASA production are directed against surface antigens on sperm, which can interfere with sperm motility and transport through the female reproductive tract, inhibiting capacitation and acrosome reaction, impaired fertilization, influence on the implantation process, and impaired growth and development of the embryo.

Terms oligospermia, oligozoospermia, and low sperm count refer to semen with a low concentration of sperm [1] and is a common finding in male infertility. Often semen with a decreased sperm concentration may also show significant abnormalities in sperm morphology and motility (technically oligoasthenoteratozoospermia ).
There is evidence suggesting a significant association between vitamin D serum concentrations and the quality of sperm in men, characterized by the sperm's motility and progress motility. [23] Because the quality of men's sperm is influenced by genetics, results should be interpreted cautiously.
Males may also experience issues in sperm motility and morphology, which means the sperm are less likely to make it to the egg or to be able to fertilize the egg. [6] Female infertility could be a result of an issue regarding their uterus, ovaries, or fallopian tubes and can be impacted by various diseases, endocrine/hormone disruption, or ...
