Pre-weighted container for semen analysis. Volume can be determined by measuring the weight of the sample container, knowing the mass of the empty container. [29] Sperm count and morphology can be calculated by microscopy. Sperm count can also be estimated by kits that measure the amount of a sperm-associated protein, and are suitable for home use.
In some cases the hamster zona-free ovum test may also be used to diagnose fertility. Genetic testing and chromosomal analysis can rule out some other causes of male infertility, such as Klinefelter syndrome. A recent study identified epigenetic patterns in male sperm that may contribute to infertility. [21]

Male collection kits are used for sending semen to a laboratory for analysis, for sending semen to a partner for artificial insemination if the male is absent, and, most commonly, by private sperm donors or sperm donors donating through an agency. A sperm agency will generally supply the male collection kit to donors.
