The authors examine the implications for individuals and society of how semen is provided for use in donor insemination treatment. In particular, they focus on whether 'donors' make a gift of their semen or are paid. The role of health professionals in shaping the nature and meaning of semen provision is also explored. The currently predominant practice of buying semen is compared with other re...
Epidemiological data indicate a sexual route of transmission of acquired immune deficiency syndrome (AIDS) associated Kaposi's sarcoma. Recently human herpes virus 8 (HHV-8) has been proposed as the aetiological agent for development of Kaposi's sarcoma. Further the virus has been reported in semen obtained from healthy men. In Denmark strict biochemical and microbiological criteria are used in...
In a prospective, randomized study of insemination with donor semen, intracervical insemination by straw was compared with insemination using a cervical cap with an intracervical reservoir. A total of 91 patients completed 486 treatment cycles. There were no significant differences in age, parity, indication for insemination by donor, or method of cycle monitoring between women who became pregn...
Sperm donation in China is different from that in other countries due to cultural, social and political factors. This research presents the current status of sperm donation in Mainland China and highlights some problems. Between January 2003 and December 2009, 19 471 sperm donors were screened totally and 6467 donors (33.2%) were recruited. The primary reasons for non-recruitment were either in...
Newill is sympathetic to the problems and motivations of infertile couples who seek to reproduce through artificial insemination by donor (AID). He refutes social, genetic, and moral objections to the procedure and favors protecting the anonymity of semen donors.
The article reports qualitative research findings which explored the meanings of kinship and genetic knowledge of fifteen pre-1990 semen donors in the UK. This is presented in the context of public and academic debates about the regulation of access to genetic information, genetic information as intellectual property and kinship knowledge, and the multiple ownership of genetic information. Seme...
Cryopreservation has the capacity to extend spermatozoa’s lifespan and viability. In addition, the semen samples can be collected, preserved and stored or sent to distant locations and still be used long after the death of the semen donor. In this study for the vitrification of dog sperm (fresh and swum-up sperm), different cryopreservation mediums on the basis of glycerol, milk and egg yolk we...
A retrospective analysis of sixty one prospective donors who visited the cryobank in person from August 1999 to December 2001 was done. The study evaluated the acceptance rate of prospective semen donors and semen characteristics in order to assess the fertility potential of the supposedly normal population of young men. The outcome of the various screening processes--history taking, infection ...
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...
