چکیده

Various techniques constitute assisted reproduction, one of which is gamete intra-fallopian transfer (GIFT). The first example of GIFT involved primates during the 1970s, however, the technology was unsuccessful until 1984 when an effective GIFT method was invented by Ricardo Asch [4] at the University of Texas Health Sciences Center [5] and the procedure resulted in the first human pregnancy [6]. The GIFT technique was created in hopes of generating an artificial insemination [7] process that mimicked the physiological sequences of normal conception [8]. The technique was further advanced at the Center for Reproductive Health at the University of California [9], Irvine, when Asch and his associate Jose Balmaceda [10] employed a newly developed catheter into the GIFT procedure that eliminated the need for general anesthesia in the later stages of the procedure.

A possible effect of different light sources on pregnancy rates following gamete intra-fallopian transfer.

A retrospective study of 34 sequential gamete intra-Fallopian transfer (GIFT) procedures suggested a significant effect on pregnancy rates associated with the different laparoscopic light sources, with a pregnancy rate of 50% in 22 cycles using a halogen light source and 9% in 12 cycles using a xenon light source. Other explanatory variables were explored, but none was to have a significant eff...

Is the male involved in the aetiology of ectopic pregnancy?

We have previously observed a low incidence of ectopic pregnancies in couples having gamete intra-Fallopian transfer (GIFT) with donated spermatozoa. Based on findings in both animal and human models, we proposed the hypothesis that sperm defects may be associated with the expression of paternal genes which cause abnormal early embryo development and predispose the embryos to interact inappropr...

Effect of time of oocyte collection and site of insemination on oocyte transfer in mares.

The objective of the study was to compare embryo development rates after transfer of oocytes collected 22 or 33 h after hCG injection into recipients inseminated within the uterus or the oviduct. Oocytes were collected at approximately 22 or 33 h after hCG injections and incubated for approximately 16 or 1.5 h, respectively, before transfer. Intrauterine inseminations using 1 x 10(9) progressiv...
