Hi! I canât say I know what your problem is but I did read that the clumps in the sperm may be nothing harmful and are not necessarily a sign of an underlying disease. They can however, be painful sometimes and their cause might not always be found.
In addition to differences between genes, the arrangement of nucleic acids can differ between copies of the same gene. This results in different forms of individual genes. Different forms of a gene are called alleles. Organisms that reproduce sexually receive one complete copy of their genetic material from each parent.
If an individual has the same two alleles for a gene, this is called homozygous. If an individual has two different alleles for a gene, this is called heterozygous. The combination of alleles an individual inherits is called the genotype. What that individual actually looks like is called the phenotype.
