At Wilmington Reproductive Laboratories, we work with your physician to diagnose infertility issues through laboratory analysis.

Semen Analysis

Diagnosing male infertility starts with a semen analysis. A semen analysis provides information about:

  • The volume of semen ejaculated
  • The concentration of sperm within the ejaculate
  • Motility and quality of movement of sperm cells
  • Normal and abnormal morphological forms


Our lab staff prepares the patient’s sperm specimen for intra-uterine insemination (IUI), a preliminary therapy to help physicians treat infertile couples.

Washing the semen prepares the sperm for IUI by

  • Separating sperm from seminal fluid, thereby increasing uterine compatibility
  • Concentrating the number of motile sperm available
  • Improving motility, or movement, of the sperm cells

Sperm washing improves the odds that a man’s sperm will survive and fertilize his female partner’s egg. This increases a couple’s chances of conception.

Wilmington Reproductive Labs’ staff uses a prewashing analysis to help determine the methodology to optimize sample quality. In most cases a density gradient wash is preferable to a simple pellet wash. Additional processing techniques are available to help improve your sample at Wilmington Reproductive Labs.

Wilmington Reproductive Laboratories will be opening an in vitro fertilization (IVF) laboratory in the near future in conjunction with Dr. Karenne N. Fru, MD PhD, of Coastal Reproductive Endocrinology and Infertility, in order to expand our infertility services.
