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. The ...
Many women have reported finding treatment for infertility stressful and a cause of relationship difficulties with their partners. The fear of failure was the most important barrier to treatment. Females, in studied cases, typically experience more adverse effects of infertility and treatments than do males.
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.

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 ...
Furthermore, hyperthyroidism, an excess of thyroid hormones, has been associated with reduced semen volume, reduced sperm density, motility, and morphology. Studies in humans show that an excess of circulating thyroid hormones during thyrotoxicosis results in asthenozoospermia, oligozoospermia, and teratozoospermia. These abnormalities ...
Various studies in Finland, Southern Tunisia, and Argentina also showed a decline in sperm count, motility, morphology, and seminal volume. Males from India had a 30.3% decline in sperm count, 22.9% decline in sperm motility, and a 51% decrease in morphology over a span of a decade.
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 ...
Necrospermia is usually confused with asthenozoospermia, which is the inability of the sperm to move even when alive. To check for necrospermia, samples with a high percentage of immobile sperm are stained to check for vitality. If they are dead sperm they will be stained, as the membrane is broken and the dye enters indiscriminately.
