A sperm collecting apparatus that has a generally cylindrical housing and an inner sleeve disposed inside the housing and made from a gel-like material. The housing defines an interior chamber and has a proximal opening at a proximal end of the housing. The inner sleeve defines an internal insertion channel that is sized for closely receiving a human penis and has an insertion opening at the proximal opening of the housing, The length of the housing is adjustable in length. The housing includes a proximal end configured for telescopic engagement with a housing distal end so that the housing proximal and distal ends can be moved longitudinally with respect to each other to adjust the length of the housing. The housing distal portion includes two opposing side portions configured so they can be removably assembled together.
