Cytomegalovirus detection in cryopreserved semen samples collected for therapeutic donor insemination.

Clinical Variables Affecting The Pregnancy Rate of Intracervical Insemination Using Cryopreserved Donor Spermatozoa: A Retrospective Study in China

Sperm Characteristics in Cryopreserved Buffalo Bull Semen and Field Fertility

Semen quality and its relationship to fertility are major concern in animal production. The aim of this study was to assess the relationship between frozen thawed sperm characteristics and fertility following in vivo fertility through Artificial Insemination(AI). Semen samples were collected from four buffalo bulls. Semen volume and sperm concentration appeared to be significantly different (P0...

Birth of the first mithun ( Bos frontalis) calf through artificial insemination.

The study describes the standardization of a suitable semen cryopreservation protocol for the first time in mithun (Bos frontalis) and birth of the first mithun calf through artificial insemination. The semen samples were collected from adult bulls through the rectal massage method and cryopreserved in liquid nitrogen using tris-egg yolk-glycerol diluent. The diluted semen samples were packaged...

PCR assessment of Chlamydia trachomatis infection of semen specimens processed for artificial insemination.

In order to ascertain the microbiological quality of stored semen specimens processed for artificial insemination by a donor (AID), we developed a PCR assay targeting the chlamydial plasmid to detect Chlamydia trachomatis in semen. The lower limit of detection of this assay corresponded to 2.5 to 5 elementary bodies per microl of semen. A total of 669 cryopreserved ejaculates from 97 asymptomat...

Sexually communicable micro-organisms in human semen samples to be used for artificial insemination by donor.

Two hundred and thirty seven semen samples from 10 institutes for artificial insemination by donor (AID) in Belgium and the Netherlands were tested for the presence of Neisseria gonorrhoeae, Chlamydia trachomatis, Mycoplasma hominis, Ureaplasma urealyticum, herpes simplex virus, and cytomegalovirus. The incidence of these micro-organisms in the semen samples was 0%, 6.3%, 4.6%, 35.9%, 0%, and 0...
