– Most hormones work through interactions with the brain and have either a direct or indirect influence on each other. Testing key hormone levels for either over or underproduction can identify irregularities that may adversely affect sperm production, or development.
– Identifies chromosomal abnormalities and DNA mutations that correlate with various infertility related disorders. The effects can range from causing a spontaneous abortion to having no sperm production capabilities.
– In some cases the male immune system itself can react to its own sperm as if they were invading cells. The immune system attacks the sperm and significantly impedes their ability to fertilize an egg.
|Infectious Disease Screen
– During the diagnostic work-up various blood tests have to be conducted prior to assisted reproduction attempts in order to verify the presence or absence of various infectious diseases. Having one of these infections could be a contributing factor to a couple’s infertility issues thereby affecting the outcome of an assisted reproduction attempt. Another important reason for this testing is the fact that many of these infections can be passed along to the baby, potentially jeopardizing their health and the pregnancy.
|Sperm DNA Structure and Function
– Sperm are essentially made up of two components: 1.) the DNA (the message) that combines with the DNA from an egg to create an embryo and 2.) the proteins that make up the sperm (the vehicle) whose job it is to house, protect and deliver the message (DNA). Most sperm tests look almost exclusively at the vehicle to assess things like how many, what shape and how the sperm bind to the egg. Sperm DNA tests look at the message to make sure it can be opened and read properly once it has reached its destination, the egg.
