Abstract: The present invention relates generally to a method for predicting the fertility potential in a male mammal. In particular it relates to a method for predicting the fertility potential in a male mammal by determining the expression of at least one protein of the vitamin D metabolising machinery in a semen sample. The expression level of the at least one protein of the vitamin D metabolising machinery is then indicative of the fertility potential of the subject. An object of the present invention relates to a method, which can predict whether the semen quality is sufficient to achieve pregnancy spontaneously or if the couple should proceed to assisted reproduction or further investigation.

Abstract: The present invention provides a method for the detection of testicular cancer and/or precursors hereof by screening a sample for the presence of at least two markers in the same cell, wherein the sample is a semen sample and/or an ejaculate from a male human being.

Abstract: The present invention relates to methods and kits for identification of testicular carcinoma in situ (CIS), gonadoblastoma (a CIS-like pre-cancerous lesion found in dysgenetic gonads) and CIS-derived cancers based on at least one of the biomarkers included in the invention. It also relates to diagnosis of a subject's status of the testicular carcinoma in situ and the derived cancers based on the measurement of a relative abundance of one of the biomarkers.
