This test may be used as a screen to asist in determining which men may need the assistance of "ICSI" fertilization by our embryology team. Sperm from the man being tested are exposed to one half of the split zona pellucida, while sperm from a man known to have "normal-fertile" sperm are exposed to the other half. There have been many attempts made to develop a Laboratory test that will accurately predict the ability of a human sperm to fertilize a human egg. Some of the common causes of male infertility are extremely high fever, failure of the testicles, obstruction of the tubes that carry semen to the penis, and a less than normal amount of sperm in the sample.

Abnormal Sperm Counts
Putting it all together, one looks for the total number of "good" sperm in the sample: The importance of diet, vitamins, malnutrition, and nutrient deficiencies in male infertility. A sperm analysis is completed through masturbation so it is noninvasive. Any positive changes you've made won't show up for several months. There are steps you can take at home to increase your chances of getting your partner pregnant, including:. For a detailed explanation of the "hamster test" click here.
Semen analysis: MedlinePlus Medical Encyclopedia

Very low volume may indicate a problem with producing seminal fluid, a duct blockage or a prostate problem. The SpermCheck Fertility Test is an inexpensive, at-home test that can be used to determine if your sperm count is in the normal range over 20 million per milliliter. A semen analysis showing no sperm with evidence of testis atrophy in a couple considering testis sperm extraction with IVF and ICSI Y microdeletion assay and karyotype analysis 3. With a change to an even lower cut-off value of 15 million spermatozoa per mL as suggested in the new WHO manual, more subfertile men may be used as normal controls, making the studies less powerful or, in some cases, even meaningless. High mitochondrial membrane potential MMP was attributed to cells with an intense red fluorescence signal. For most men, concerns about the quality and quantity of their sperm arise only… Read More.
By testing for sperm DNA fragmentation, many cases of formally "unexplained" infertility can now be explained. Even the previous WHO cut-off value of 20 million spermatozoa per mL was probably too low to identify a significant group of males who need to be referred to andrology experts 7. Fertility Preservation Egg freezing can free you from the biological clock to extend your age of fertility. What is a normal sperm count?
