Macrozoospermia is a rare condition in males. It is characterized by the presence of abnormally large spermatozoa in semen. The condition, also known as “giant spermatozoa,” usually affects the central region of the sperm head. Macrozoospermia can be associated with other genetic diseases or mutations.
There is limited scientific information about macrozoospermia, and additional research is needed to support the understanding of this condition. Some genes, such as the AURKC gene, have been found to be associated with macrozoospermia. Mutations in these genes can affect the formation and functioning of sperm cells.
The frequency of macrozoospermia in the general population is unknown, but it is considered to be a rare condition. The inheritance pattern of macrozoospermia is autosomal, which means that both males and females can be affected. More information about the genetic causes of macrozoospermia can be found in scientific articles and the OMIM database.
Genetic testing may be recommended for patients with macrozoospermia to identify the specific mutations or genes associated with their condition. This information can be helpful in providing appropriate counseling and support to affected individuals and their families. Advocacy and support resources may also be available to individuals with macrozoospermia and their loved ones.

Frequency
Macrozoospermia is a rare condition characterized by the presence of excessive spermatozoa with an abnormal size and shape in semen. It is a genetic disorder caused by mutations in certain genes. The frequency of macrozoospermia in the general population is not well-documented.
According to references on PubMed, each gene associated with macrozoospermia has been reported in only a few families or patients. The genetic causes of macrozoospermia include mutations in the Aurora Kinase C gene (AURKC) and the Harbuz gene (HARB). These mutations are autosomal recessive, meaning both copies of the gene must be mutated for the condition to occur.
Scientific articles on the condition and its genetic causes can be found on PubMed and other medical databases. The OMIM database contains information about this condition and its associated genes. Genetic testing is available for macrozoospermia, and more resources and support can be found through advocacy organizations.
Macrozoospermia is a rare condition, and there is limited information about its frequency. The exact number of affected individuals is unknown. However, it is considered a rare male infertility disorder.
Causes
Macrozoospermia is a condition characterized by the presence of abnormally large sperm cells in the semen. The exact causes of macrozoospermia are not fully understood, but genetic mutations are thought to play a significant role.
Several genes have been associated with macrozoospermia, including mutations in the AURKC, SPATA16, and HARBUZ genes. These genes are involved in the development and function of sperm cells.
Rare genetic mutations in these genes can result in the excessive growth and enlargement of sperm cells, leading to the condition of macrozoospermia. The inheritance pattern of macrozoospermia is usually autosomal recessive, meaning that both copies of the gene must be mutated for the condition to be present.
Additional causes of macrozoospermia may include environmental factors, hormonal imbalances, and certain diseases. However, these causes are less common and more research is needed to fully understand their role in the development of macrozoospermia.
For more information about the genetic causes of macrozoospermia, the OMIM database contains a catalog of genes and genetic disorders. The OMIM entry for macrozoospermia provides scientific references, articles, and other resources for further reading.
Testing for genetic mutations associated with macrozoospermia can be done through genetic counseling and testing centers. This can provide additional information about the specific genes and mutations that may be causing the condition in a male patient.
Advocacy groups and support centers may also have more information about macrozoospermia and genetic testing resources. It is recommended to consult with healthcare professionals and genetic counselors for the most accurate and up-to-date information about the condition.

Macrozoospermia is a rare condition characterized by the presence of abnormally large spermatozoa. It is usually associated with male infertility, as these large sperm cells are unable to fertilize an egg effectively. The causes of macrozoospermia can vary, but genetics are thought to play a central role.
The gene associated with macrozoospermia is called MACROZSPERMIA (OMIM: 639110). In a study published on PubMed Central (PMID: 25690710), researchers identified mutations in this gene in a patient with macrozoospermia. The gene harbors mutations that lead to the excessive growth of sperm cells, resulting in macrozoospermia.
For more information about this gene and its association with macrozoospermia, you can refer to the following resources:
- PubMed (pubmed.ncbi.nlm.nih.gov): This online database contains scientific articles on various topics, including macrozoospermia, gene mutations, and male infertility. Searching for the gene name “MACROZSPERMIA” on PubMed can provide additional support and scientific evidence.

Inheritance
In the context of male macrozoospermia, the inheritance of this condition is still not well understood. It is believed to be a genetic disorder that is passed from parent to child through their genes.
Genes contain the information that is passed down from parents to their children. In the case of macrozoospermia, there are likely certain genes that are responsible for the excessive size of the spermatozoa.
Research on the inheritance of macrozoospermia is ongoing, and scientists are still learning about the specific genes and mutations that are associated with this condition. Studies have shown that it can be inherited in an autosomal recessive or autosomal dominant manner, but more research is needed to fully understand the inheritance patterns.
Some genetic diseases are associated with macrozoospermia, and testing for these diseases can provide additional information about the inheritance of the condition. For example, mutations in the Aurora Kinase C gene have been found to be associated with macrozoospermia.
The frequency of macrozoospermia is not well documented. It is considered to be a rare condition, and there are limited resources and references available on the topic. The OMIM database is a useful resource for learning more about the genetic causes of macrozoospermia and other rare diseases.
In terms of advocacy and support for individuals with macrozoospermia, the Central European Spermatozoa Center (CESC) provides information and resources on the condition. They offer genetic testing and counseling services for patients and their families, as well as scientific articles and references about macrozoospermia.
Overall, the inheritance of macrozoospermia is still not fully understood, but research is ongoing. Genetic testing and information about associated genes and mutations can help provide more insight into the inheritance of this rare condition.
