The New Jersey Center for Fertility and Reproductive Medicine and Dr. Eric Daiter review current information on
sperm and male factor fertility on this website.
Mature motile sperm (spermatozoa) are required for natural human fertilization and reproduction. Semen that
is released into the female reproductive tract normally contains greater than twenty million (20,000,000) sperm
in every milliliter (mL). Sperm cells are formed in the human testes (testicles), they continue to mature and
develop motility within a structure called the epididymis (located on top of the testis), and these motile sperm
cells (spermatozoa) are then released during ejaculation. Following release of sperm in semen, the sperm
cells undergo a change called "capacitation" to become "hypermotile" (very agitated with rapid movement) and
become able to penetrate the egg�s outer gelatinous shell (zona pellucida) to fertilize the egg.
A semen analysis is the most common diagnostic test for sperm, with a low sperm count representing the most
common abnormality. Sperm motility studies and sperm morphology (shape) may also suggest a problem with
male infertility.
Sperm abnormalities are not uncommon and these abnormalities may result in decreased fertility. Up to one
third of all human infertility is thought to be primarily due to a male factor. There are several different causes for
sperm disorders, including problems with the testes or within the scrotal sac, the pituitary gland, the
hypothalamus or the central nervous system (CNS).
Dr. Eric Daiter and The New Jersey Center for Fertility and Reproductive Medicine encourage the viewer to
explore the contents of this site, which reviews the physiologic events that result in normal sperm production,
tests currently available to detect abnormal sperm, known causes for abnormal sperm production or male
infertility, and clinically available treatment options.
The information within these tutorials is intended to be solely educational. The knowledge and competence
that the viewer may expect to develop within the complex medical field of infertility is not a substitute for the
medical education that physicians obtain during their medical curriculum and training.
With this in mind, many couples are able to effectively use the knowledge that they gain about human
reproduction to guide them through the difficult (and often expensive) process of obtaining medical (infertility)
care.
