The aim of the present study was to compare the effects of two culture media on in vitro fertilized embryo produced by fresh and cryopreserved buck semen respectively. The in vitro fertilized embryos from both semen sources were cultured separately in the two media groups viz., Research Vitro Cleave-BSA (RVCL-BSA) and RVCL-Blast-BSA media. Under RVCL–BSA medium, the fresh semen produced higher ...

The genetic improvement of agriculturally important species and disease control are of fundamental importance to the success of a sustainable agri-food industry. In this sense, artificial insemination (AI) is arguably the most important tool contributing to the advancement of modern animal production. Through AI, 1 ejaculate from a genetically superior male can be used to impregnate multiple fe...

BACKGROUND Adult cancer patients are routinely offered pre-treatment sperm cryopreservation. However, only recently has the welfare of adolescent cancer sufferers gained momentum, including their infertility, and unsurprisingly relatively little is known about their semen quality and feasibility of cryopreservation. METHODS AND RESULTS A total of 238 adolescent cancer patients referred to our...

This study was carried out to investigate effects of copper sulphate (CuSO4) additive to semen extenders on sperm parameters: progressive motility, viability, membrane integrity and DNA damage, after semen dilution and cryopreservation. Semen samples of 5 buffalo bulls of 3-5 years old were collected at 5 different occasions during the autumn 2011. A total number of 25 samples were used in each...

In mares, a physiological endometritis ensues following the deposition of semen into the uterus. This response is thought to be due to the antigenic nature of spermatozoa, specifically the activation of complement, and may be modulated by the presence of seminal plasma component of the semen. The removal of seminal plasma during cryopreservation of spermatozoa may account for the longer duratio...

to construct a semen bank, the collection of donated semen has to be done and an important concern is the safety of collected semen. the contamination is a big problem. basically, the infectious pathogens can exist within donated semen, hence, a good donor screening is very important. although viruses have an indirect role in sperm quality, but the evidence in banked semen is presently lack. th...

Environmental influences on reproduction and semen production in the buck, the problem of interaction between seminal plasma and egg yolk or milk constituents in diluent, liquid storage and processing of semen for freezing are discussed. A review is given on the use of frozen-thawed semen for artificial insemination (AI) in spontaneous and induced oestrus and factors influencing the fertility.

Methods of semen collection and artificial insemination (AI) in poultry, requirement for diluents, methods of liquid and frozen storage of avian semen and evaluation of spermatozoa after storage for fertilizing ability are reviewed. Frozen storage of semen from non-domestic birds is also briefly discussed.

The present study was conducted to determine correlation of semen quality with libido in different breeds of bulls. Four mature cattle bulls from each of Friesian, Jersey, Achai, Cross (Friesian x Sahiwal) and Sahiwal in different age (1-3, 3-5 and above 5 years) were selected. For age grouping, data of the entire breed was pooled. Libido was measured in terms of time (seconds) taken for the en...
