A sperm collecting apparatus includes a plurality of rings wherein each ring includes an inner sleeve comprising a gel-like material. The inner sleeve defines an internal insertion channel portion that is sized for closely receiving a human penis. Each ring can be placed in a concentric stacked relationship with other similar rings so that the insertion channel portions of the rings form an elongated insertion channel. A connecting case holds the rings in the concentric stacked relationship. The length of the insertion channel can be adjusted by varying the number of rings in the concentric stacked relationship. Each of the rings is removable from and replaceable within the connecting case.
