Normal spermatogenesis in a man with mutant luteinizing hormone.

3 Nov 2009 Men with mutations in LHB, the gene encoding the beta subunit of luteinizing hormone (LHB), have azoospermia with absent or few fetal Leydig cells. We report a mutation in LHB in a man and his sister. The man presented with absence of virilization, ... Read more...

Transcriptional profiling of the hormone-responsive stages of spermatogenesis reveals cell-, stage-, and hormone-specific events.

29 Sep 2009 Spermatogenesis occurs within the highly complex seminiferous epithelium. This cyclic process is accompanied by dynamic stage-specific transcriptional changes and is driven by androgens and FSH by mechanisms that are unclear. Here we report the ... Read more...

TSPY1 copy number variation influences spermatogenesis and shows differences among Y lineages.

20 Sep 2009 CONTEXT: TSPY1 is a tandemly-repeated gene on the human Y chromosome forming an array of approximately 21-35 copies. The testicular expression pattern and the inferred function of the TSPY1 protein suggest possible involvement in spermatogenesis. ... Read more...
