Semen Analysis

The semen analysis- The semen analysis is one of the most important fertility tests because male infertility is present in up to 47% of infertile couples. The female should usually not undergo any fertility therapy until the semen analysis has been completed.

The semen analysis measures several sperm characteristics defined by the Kruger Strict Criteria, some of which are listed below. If possible, the semen analysis should be performed by a reproductive laboratory because of their extensive infertility experience.

The "major" sperm evaluation characteristics include:

• Number of live sperm in the ejaculate. Normal = > 20 million per milliliter
• Presence of white blood cells that could indicate an infection. Normal= < 5 white blood cells per microscopic field.
• Volume of fluid in the ejaculate. · Motility (ability to swim in a straight line). Normal = > 50%
• Shape and size of the sperm. Normal = >14% "highly normal forms"

Abnormalities may indicate the need for treatment with technologies such as intrauterine insemination (IUI) or intracytoplasmic sperm injection (ICSI). Fortunately, ICSI makes it possible for men with little or no sperm in their ejaculate to father children. IUI is often successful for mild male factor or cervical factor infertility. Male treatments, including IUI and ICSI, are discussed in the male infertility section.
