For all mares studied, a greater percentage of oviductal sperm were recovered from the ipsilateral oviduct following uterine horn insemination (77.3%) than resulted from uterine body insemination (53.8%). The number of oviductal sperm recovered from reproductively normal mares and mares with delayed uterine clearance was not different. Authors’ Addresses: Dept. of Large Animal Medicine & Surger...

In all domestic species, acceptable pregnancy rates with frozen-thawed semen are only achievable with intrauterine insemination. Unlike the cow and the goat, the cervix of the ewe is a formidable barrier to penetration for transcervical intrauterine insemination not only due to the physical size of the canal and a narrow luminal diameter (even at estrus), but also due to it’s caudally facing, e...

This Article attempts to untangle Jewish law regarding assisted reproductive technologies (ARTs), namely artificial insemination with husband’s sperm, artificial insemination with donor sperm, and in vitro fertilization. The author examines teachings by prominent Jewish law scholars and clarifies basic schools of thought regarding each method. He explores Jewish law prohibitions on incest and a...

insemination by artificial or natural means, thereby minimizing the amount of error introduced in experimental work by the use of females in unknown physiological condition. In critical experiments by using for an indicator a vasectomized male, homozygous for one color factor, and for the later insemination sperm from a male homozygous for another color factor, one will have a definite breeding...

Natural service boars and boars who’s semen is collected for artificial insemination make up a relatively small portion of the pig population. This may partially explain the limited amount of data on the nutritional requirements and feeding practices of adult boars. Several research and literature reviews have been done, Kemp and den Hartog (1989), Colenbrander and Kemp (1990), Close and Robert...

The present article reviews the empirical research regarding the parent-child relationships and the development of children in donor insemination (DI) families. Over the years, follow-up studies have appeared sporadically and, despite the varying quality of the research methods, preliminary findings have emerged. Heterosexual DI parents were psychologically well adjusted and had stable marital ...

A national data set of artificial inseminations in US Holsteins was used to obtain genetic evaluations for conception rate (CR). The objective of this study was to investigate the feasibility and resulting accuracy from using all available phenotypic, pedigree, and genomic information. Evaluations were performed by regular BLUP or by BLUP with the traditional pedigree and genomic relationships ...

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.

Given the complex and dramatic array of issues currently facing us in reproductive ethics, bioethicists working on the topic might be forgiven feelings of trepidation when they cast their minds toward the next century. Currently, technologies such as artificial insemination by donor (AID), once the source of intense controversy, are used on a routine basis; mainstream newspapers carry advertise...
