Amy E.T. Sparks
Background: Whether anesthetic agents administered during gamete intrafallopian transfer (GIFT) affect reproductive outcome is controversial. This multicenter pilot trial and survey had two purposes: to evaluate the effect of propofol, nitrous oxide, midazolam, and isoflurane on pregnancy outcome after GIFT, and to determine if a larger prospective, randomized study is warranted. Methods: A written invitation was mailed to all 50 fertility programs in the United States that are members of the Society for Assisted Reproductive Technology and perform more than 30 GIFT procedures per year. They were invited to contribute information from the medical records of women who underwent GIFT …

Development Of An Immunocontraceptive Vaccine. Current Status, H. Feng, J. Sandlow, Amy Sparks, A. Sandra
Amy E.T. Sparks
Development of an effective and modern contraceptive vaccine is a key factor in the global issue of regional population growth as well as agricultural, medical, economic and social development. A review was done of the current medical literature concerning development of an immunocontraceptive vaccine and relative molecular biology technology. Various approaches have been taken to identify candidate-specific antigens for immunocontraceptive development, such as sperm, zona pellucida and hormonal antigens. Suppressed fertility and the reversibility of these effects on mammalian species, including humans, have been demonstrated. The successful results obtained so far support the continued investigation for an effective immunocontraceptive vaccine.

Need For Sperm Retrieval And Cryopreservation At Vasectomy Reversal, C. Schrepferman, M. Carson, Amy Sparks, J. Sandlow
Amy E.T. Sparks
Purpose: Controversy exists on whether to obtain sperm for cryopreservation routinely at vasectomy reversal. With recent improvements in in vitro fertilization with intracytoplasmic sperm injection, it is now possible to obtain a small amount of testicular tissue for cryopreservation in the event of reversal failure. However, to our knowledge no studies exist of who is most likely to benefit from this procedure. Materials and Methods: We reviewed 84 consecutive vasectomy reversals performed by 1 surgeon (J. I. S.) between July 1996 and March 2000 with followup available for 77. We grouped cases by procedure as vasovasostomy, vasoepididymostomy and vasovasostomy with …

Culture Systems: Embryo Culture And Monozygotic Twinning, Amy Sparks
Amy E.T. Sparks
The incidence of monozygotic twinning in pregnancies achieved with assisted reproductive technologies (ART) is significantly higher than spontaneously conceived pregnancies. The factors associated with ART that predispose the embryos to splitting are not well-characterized. Assisted hatching and extended embryo culture are two ART laboratory methods that have been risk factors for monozygotic twinning. The methods and strategies that may be employed to avoid monozygotic twinning are discussed in this chapter.

BACKGROUND: Rodent and in vitro studies have demonstrated the estrogenicity of bisphenol A (BPA). However, few studies have examined the relationship between human exposure to BPA and male reproductive function. OBJECTIVES: We investigated the relationships between environmental BPA exposure and reproductive parameters, including semen quality and male reproductive hormones, in prospectively recruited fertile men. METHODS: Participants (n = 375) were partners of pregnant women who participated in the Study for Future Families in four U.S. cities, and all of the men provided blood, semen, and urine samples. BPA was measured in urine. Serum samples were analyzed for reproductive hormones, including …

In vivo fertilized embryos were surgically collected from superovulated dairy cows to evaluate microinjection on embryo development and utilized the polymerase chain reaction technique for selection of transgenic embryos. Seventy-two percent of the embryos with visible pronuclei or nuclei were microinjected with DNA, and the remaining 28% served as uninjected controls. All embryos were cocultured with bovine oviductal epithelial cells. Mean final development scores of embryos within the same initial cell stage at collection were unaffected by microinjection. After 144 h of culture, 45% of the microinjected embryos developed to the morula or blastocyst stage. The transgene was detected in …

Amy E.T. Sparks
Since 1986, we have performed microscopic reconstruction in 18 men following failed microscopic vasectomy reversal. Between 1994 and 1996, nine couples have undergone microscopic epididymal sperm aspiration (MESA)/ intracytoplasmic sperm injection (ICSI) treatment for male infertility due either to congenital absence of the vas deferens (CAVD) or inoperable excurrent duct obstruction. We compared the cost efficiency of repeat vasectomy reversal to that for MESA combined with ICSI/in-vitro fertilization (ICSI/IVF). The cost of male partner procedures (vasectomy reversal, MESA) was based on physician and hospital charges, while the cost of ICSI/IVF included preparation of the female partner (medications and physician charges) …

Follicular development and ovulation were examined in superovulated Nubian and Nubian-cross dairy goats following prostaglandin F-2 alpha (PGF(2 alpha)) and/or gonadotropin releasing hormone (GnRH) treatment. Estrus was synchronized with Synchromate-B(R) implants. Superovulation was induced with follicle stimulating hormone (FSH) and augmented with GnRH and/or PGF(2 alpha). The PGF(2 alpha) treatment was administered on Day 2 of superovulation. Implants were removed from all goats on Day 3 of superovulation. The GnRH treatment was administered 24 h after implant removal. All does were exposed to fertile males for 48 h at the time of GnRH injection. Surgical embryo recovery and ovarian response …

PURPOSE OF REVIEW: Cystic fibrosis (CF) is the most common genetic disease within the white population and leads to premature respiratory failure. Approximately, 60 000 individuals are currently living with CF in North America and Europe, almost half of whom are adults. RECENT FINDINGS: Dozens of studies across the globe indicate that CF adults have low bone density and increased rates of fractures. This genesis of the problem appears to be in late childhood to adolescence. SUMMARY: Prevention and treatment of CF-related bone disease must address the myriad risk factors (decreased absorption of fat-soluble vitamins due to pancreatic insufficiency, altered …

Gamete Microsurgery For Assisted Fertilization, Amy Sparks
Amy E.T. Sparks
Several methods of gamete microsurgery have been proposed to facilitate the union of the spermatozoon and oocyte in infertile couples, Partial zona dissection, subzonal sperm insertion, and intracytoplasmic sperm insertion are the three techniques currently being used for assisted fertilization in human in vitro fertilization laboratories. Fertilization and pregnancy rates after partial zona dissection and subzonal insertion have been Variable and rather low. Recent reports of relatively high fertilization and pregnancy rates achieved after intracytoplasmic sperm insertion have rejuvenated interest in gamete microsurgery. Methods for each procedure are described, Studies which have attempted patient selection for gamete microsurgery are discussed. …
