BACKGROUND One of the challenges faced by equine breeders is ensuring delivery of good quality semen doses for artificial insemination when the mare is due to ovulate. Single Layer Centrifugation (SLC) has been shown to select morphologically normal spermatozoa with intact chromatin and good progressive motility from the rest of the ejaculate, and to prolong the life of these selected spermatoz...

The Warnock Committee decided not to sanction artificial insemination by donor (AID) and in vitro fertilisation (IVF) for single heterosexual women orfor lesbian women on the grounds that it is betterfor children to be born into a two-parent heterosexual family. From an examination of the effects on children ofgrowing up in fatherless heterosexual and lesbianfamilies, thispaper questions that a...

background: research supports that in vitro fertilization causes anxiety and that anxiety can continue into the resulting pregnancy. most women who have ivf will have a less invasive treatment for infertility prior to ivf; however, it is unclear if specific less invasive treatment cycles impact anxiety that is experienced in the pregnancy resulting from ivf. methods: a prospective study was con...

This review focuses on the platform of recent advances in reproductive biotechnologies in sheep and goat. Here, we discuss some aspects of veterinary and biomedical importance in artificial insemination using sexed semen, in vitro/in vivo fertilization, interspecies in vitro fertilization, multiple ovulation and embryo transfer (MOET), somatic cell nuclear transfer and transgenic animal product...

This study follows 40 older single-mother families created with the aid of sperm donation using either insemination or in vitro fertilization. The study is based on qualitative data obtained from the mothers 3 years after a previous study with these families. The mean age of the mothers at this time was about 47 years and of the children 7 years. The findings provide insights into the mothers' ...

BACKGROUND Knowledge about the lives of single women who choose to become mothers by sperm donation is very limited. METHODS This study comprises 62 families headed by formally single women who, following their decision to give birth to a child with the aid of sperm donation, by means of insemination or in vitro fertilization (IVF), used the services of one sperm bank in Israel. RESULTS The...

The widespread debates arising from medical advances have become a familiar aspect of contemporary society, and the clinical application of man's increasing control over his physiological and biochemical systems is bound to stimulate further controversy. This review is concerned with the current debate on one of these novel advances-the fertilization of human oocytes in vitro, and their reimpla...

OBJECTIVE To examine the characteristics of women in the 1988 National Survey of Family Growth who reported having obtained medical services for impaired fecundity. METHODS From a national sample of 8450 women between the ages of 15-44, drawn from the civilian, noninstitutionalized population of the entire United States in 1988, we estimated the use of infertility services in the United State...

BACKGROUND/AIM Unknown cause of infertility exists in 10%-26% of couples with infertility problems. Treatment of these couples depends on the posibility of correcting the unidentified defect over time. Intrauterine insemination (IUI) and ovaluation stimulation are methods of choice in treatment of unexplained fertility, but if a woman is older than 37 years, in vitro fertilization (IVF) could b...

The cause of infertility is unexplained in about 22-28% of all infertile couples. The prognosis for spontaneous pregnancy in such couples is better than in those with diagnosed causes of infertility. Traditional treatment options in this group have included expectant management, clomifene citrate, intrauterine insemination with (super ovulation plus intrauterine insemination) or without (intrau...
