The only way a retrovirus can change the DNA in a sperm cell is if it successfully implants its own DNA into the sperm DNA.
Studies have been done with the HIV retrovirus to show that the virus can successfully get inside a sperm cell - but it has never been shown that the HIV virus successfully implants its DNA into the sperm DNA.
In order to get to sperm in the first place, a retrovirus has to get past the blood-testes barrier - which protects developing sperm from outside infections.
The only way HIV is able to do this is because it infects white blood cells which are able to sneak past those defenses.
So, any retrovirus that has a chance of infecting a sperm cell must first be able to get past the blood-testes barrier - which seems to be limited to only retroviruses who are able to bind to white blood cells. Cells have unique binding cites, and only certain viruses are able to attach to certain ones.

Where is the human sperm cell made?
Sperm cells are made in the testes.
Some human inherited traits are transmitted by Blood cells Bone cells Sperm cells Liver cells?
Some human inherited traits are transmitted or passes from parent to offspring by sperm cells.
How many chromosomes in normal human eggs and sperm is the same as in the body cells?
There are 23 chromosomes in human egg/sperm. In other human body cells there are 46 chromosomes.
The human immunodeficiency virus may infect what cells?
sperm cells
What are two example of sex cells and how are they formed?
Sperm and Egg cells are formed by Meiosis.
Where are human sperm cells formed?
In a man's testicles
When are human cells diploid?
All human somatic (body) cells are diploid. Only the gametes, sperm and egg cells, are haploid.
What are some types of human cells?
blood cells, white blood cells, sperm cells, brain cells.
What is one of the human differences between human egg and sperm?
The eggs are the biggest cells in the body, while the sperm is the smallest.
What are Sperm only human cells to have?
Sperm are the only human cells to have a flagellum. This is their "tail". They are also one of only two cells to have haploid number of chromosomes. The ova in females is also haploid.
Has how many chromosomes withn the egg cells?
All human gametes (sex cells), which means egg cells and sperm cells, have 23 chromosomes. When the sperm fertilises the egg, the 23 chromosomes from the egg cell and the 23 chromosomes from the sperm cell join to make cells with 46 chromosomes. In summary, all cells in the human body have 46 chromosomes, except sperm cells and egg cells, which have 23.
Number of chromosomes in eggs and sperm cells?
I assume you mean human egg and sperm cells. There is a haploid number of chromosomes in these cells. 23 chromosomes. n.
