TL;DR: The problems, aspects and methods of liquid storage and freeze-thawing of boar semen are discussed and a review is given on examination of spermatozoa by the recent fluorescent staining methods.

TL;DR: Factors influencing the fertility of stored semen and methods used for improvement are discussed, and fertility results of long-term frozen stored ram semen are given.

TL;DR: Stored spermatozoa may require less capacitation time in the female tract, and may readily fertilise oocytes if placed in their immediate vicinity, as with in vitro fertilisation, tubal or even intrauterine insemination.

TL;DR: It has yet to be determined whether seminal plasma would have similar effects on flow cytometrically sorted spermatozoa of other species, and what its effects might be on the in vivo fertility of flow sorted boar.

TL;DR: Cervical insemination with frozen-thawed semen had a relatively limited application in sheep because of its low Lambing results after cervicalInsemination varied depending on the parameters examined in the freezing technology or at insemination, but were low in comparison with those obtainable with fresh diluted semen.
