Gamete intrafallopian transfer (GIFT): an alternate method of conception in couples with unexplained infertility, endometriosis and oligo-asthenospermia.

138 treatment cycles of GIFT were carried out in couples with mainly unexplained infertility, endometriosis and male factor. The overall pregnancy rate was 24.6%, abortion 29.2%, multiple pregnancy 20.6% and ectopic pregnancy 0%. Four oocytes seem to be the optimal number of oocytes to be transferred. Patients with male factor infertility fared the worse in comparison with the other groups. Successful in-vitro fertilization of excess eggs did not correlate with a positive outcome of the GIFT procedure.

Successful pregnancy after ZIFT in a patient with congenital cervical atresia.

We report the third patient with a successful pregnancy following operative correction of congenital cervical atresia. The pregnancy was achieved through zygote intrafallopian transfer (ZIFT). Although stenosis of the newly formed cervical canal causes considerable morbidity, therapy should be aimed at the creation of a conduit for menstrual blood and for possible future pregnancy. New techniques in assisted reproduction such as in vitro fertilization-embryo transfer, gamete intrafallopian transfer, and ZIFT increase the chances of pregnancy in patients with congenital cervical atresia. A hysterectomy, as advocated until very recently, should not, in our opinion, be the first treatment of choice.

Assisted procreation in the presence of a positive direct mixed antiglobulin reaction test.

Twenty-five infertile couples in which the male had antisperm antibodies were treated by in vitro fertilization (IVF), zygote intrafallopian transfer, or gamete intrafallopian transfer in 38 cycles. In 10 females a tubal pathology was present, and in the normal female patients repeated intrauterine insemination with husband sperm had failed. The presence of an andrological factor in 17 male patients did not influence the fertilization and the cleavage of the retrieved oocytes. Although the fertilization rate of 45.8% was significantly lower than in patients with tubal pathology, the pregnancy rate was 34.2% per started cycle and 44.8% per replacement. Furthermore, the embryos were of lesser quality than in couples with tubal and idiopathic infertility. This study suggests that IVF could be considered as a useful therapeutic approach for couples with a positive direct mixed antiglobulin reaction test before advising them the use of heterologous sperm.

The incidence of multiple pregnancy after in vitro fertilization and embryo transfer, gamete, or zygote intrafallopian transfer.

This retrospective study concerns the incidence of multiple pregnancy after the replacement of three conceptus using different techniques of assisted reproduction. During a 2-year period, 713 in vitro fertilization-embryo transfers (IVF-ETs) with three embryos, 190 gamete intrafallopian transfers (GIFT) with three oocytes, and 161 zygote intrafallopian transfers (ZIFT) with three zygotes were performed. Although we observed significant differences in implantation and pregnancy rates (PRs), the three techniques resulted in high multiple PR. At 20 weeks, 16% of GIFT pregnancies, 27% of ZIFT pregnancies, and 32% of IVF-ET pregnancies were multiple. Therefore we recommend to limit the number of conceptus transferred to a maximum of three in all cases.

Assisted conception and immunological infertility.

Our work with a group involved in Assisted Conception (AC) has provided us with a perfect opportunity for making an assessment of the efficiency of the techniques used for the treatment of Male Antisperm Autoimmunization (MAA) and Female Antisperm Isoimmunization (FAI). The aim of this study is to present all the most important methods of AC used by our group for the treatment of immunological infertility, such as intrauterine insemination, intraperitoneal insemination, intrafallopian gamete transfer, in-vitro insemination and intrauterine embryo transfer, intrafallopian zygote transfer, intrafallopian embryo transfer, and gamete micromanipulation. In-vitro fecundation would appear to be particularly efficient in cases of FAI, while MAA would seem to benefit more from the use of gamete micromanipulation.

Ejaculatory failure.

Although anejaculation is a relatively uncommon occurrence in the general population, over 12,000 new cases are reported annually. Anejaculation may result from spinal cord injury (SCI), retroperitoneal lymph node dissection (RPLND), diabetes mellitis, transverse myelitis, multiple sclerosis, or psychogenic disorders. At least 30% of men with this problem are or will be married and many will seek help to remedy their infertile state. The evolution of technique and instrumentation over the least 30 years has made electroejaculation an accessible and acceptable form of therapy. Recent successes in inducing ejaculation by means of rectal probe electrostimulation or vibratory stimulation combined with assisted reproductive techniques, such as zygote intrafallopian transfer (ZIFT), gamete intrafallopian transfer (GIFT), and in vitro fertilization (IVF), have provided these men a means of producing their own biologic offspring.

Elevated day 3 serum follicle stimulating hormone and/or estradiol may predict fetal aneuploidy.

OBJECTIVE: To determine whether baseline serum FSH and/or E2 concentrations can predict the risk for fetal chromosomal abnormalities. DESIGN: Case control study. SETTING: Reproductive technology program at a university hospital. PATIENT(S): Patients who underwent dilation and curettage (D + C), and whose products of conception were karyotyped. INTERVENTION(S): Patients underwent natural conception or controlled ovarian hyperstimulation followed by intrauterine insemination, in vitro fertilization and embryo transfer, gamete intrafallopian transfer, or zygote intrafallopian transfer. MAIN OUTCOME MEASURE(S): Baseline serum FSH and E2 concentrations and fetal karyotype. RESULT(S): Genetic evaluation of 78 D + C specimens revealed 34 normal and 44 abnormal fetal karyotypes. A significantly greater proportion of women with abnormal fetal karyotype had elevated baseline serum FSH (> or =15 mIU/mL [RIA] or 10 mIU/mL [Immulite]) and/or E2 > or = 50 pg/mL [Immulite]) compared with women of normal fetal karyotype. Among karyotypically abnormal abortuses, autosomal trisomy was the most common abnormality noted (79.5%), followed by mosaicism (6.8%), triploidy (6.8%), monosomy XO (4.5%), and balanced translocation (2.3%). CONCLUSION(S): Baseline serum FSH and/or E2 concentrations may be valuable as predictors of fetal aneuploidy.
