In situ hybridization on human sperm using HPV type-specific probes.

<p>Specific hybridizations are indicated by arrows. (<b>A</b>–<b>C</b>): In situ hybridization on an HPV-16 positive sperm sample using a probe specific for HPV-16. The sample in picture <b>A</b> was simultaneously background stained with hematoxylin. (<b>D</b>–<b>I</b>): In situ hybridization on an HPV-6 positive sperm sample using a probe specific for HPV-6. (<b>J</b>–<b>L</b>): In situ hybridization on an HPV negative sperm sample using a probe specific HPV-6. This figure is a representative of three independent in situ hybridization experiments using two different HPV-6 positive samples and two different HPV-16 positive samples.
