Male
Phenotype

In vitro clinic:  Low testis weight, low seminal vesicle weight, low epididymal sperm concentration, abnormally shaped sperm heads with missing or short sperm tails, variable motility, very low IVF success.

Histology evaluation: Abnormal spermatogenesis (see 1-3) with low/abnormal spermatogonia and spermatocytes. Abnormal spermiogenesis with abnormal spermatid heads (see 2), low number of spermatids in testis lumen (see 3).

Hormone analysis: High levels of luteinizing hormone and testosterone.

*The scope of our funding includes mapping of the mutation to a chromosomal region, but in most cases does not include cloning of the gene responsible for the infertile phenotype.
