Abstract

Women undergoing in vitro fertilization with multiple embryos implanted simultaneously may be at increased risk for multiple births. The multiple birth rate in 734 successfully implanted pregnancies was analyzed in reference to the number of embryos implanted. The multiple birth rate rose significantly with two or three implanted embryos but more than three embryos did not significantly increase the multiple birth risk. Of the 31.3% overall multiple births, 0.8% were quadruplets, 5.8% were triplets, and 24.7% were twins.

20. Cryopreservation of zygotes and early cleaved human embryos

Author

Cohen, Jacques, DeVane, Gary W., Elsner, Carlene W., Fehilly, Carole B., Kort, Hilton I., Massey, Joe B., and Turner, Thomas G.

Abstract

Zygotes and 2- to 5-cell human embryos were frozen in 1,2-propanediol and sucrose; results of the first 50cycles (45 patients) are presented. A total of 41 zygotes (17 attempts at thawing) were thawed, resulting in six singleton clinical pregnancies (15% per embryo; 35% per cycle), of which three delivered, one aborted, and two are ongoing. Fifty-seven cleaved embryos were thawed in 33 other cycles, resulting in four singleton and one twin pregnancy (11% per embryo; 15% per cycle), of which four delivered and one is ongoing. Depending on the cell stage, 61% to 81% of embryos survived cryostorage, but 2-cell embryos did not implant. One fifth of cryoinjury was due to the formation of cracks in the zona pellucida. The incidence of implantation was not enhanced when more than one freeze/thawed embryo was replaced, most pregnancies being obtained from single embryo replacements. At least 8% more births are expected in addition to conventional in vitro fertilization methods when the current policy of replacing three fresh embryos and freezing the remainder using this technique is applied. This method will result in two to four times more pregnancies per spare embryo, compared with other cryopreservation methods using older embryos.

Abstract

Body mass index (BMI) has been demonstrated to affect female fertility; however, little information is available on the impact of BMI on male fertility or semen parameters. Therefore, the study objective was to determine the relationship between BMI and semen parameters, including sperm chromatin integrity. We analyzed data on semen samples from 520 men who were grouped based upon calculated BMI values (normal, 20-24 kg/m(2); overweight, 25-30 kg/m(2); obese, >30 kg/m(2)). The data collected included patient height and weight, semen volume, sperm concentration, percent sperm motility, percent sperm morphology (normal forms), and sperm chromatin integrity (DNA fragmentation index [DFI]). Data were analyzed by regression analysis and analysis of variance (ANOVA) with Tukey's test for multiple pairwise comparisons. The overall BMI mean (+/-SEM) was 27.5 (+/-0.49) kg/m(2). Linear regression revealed a significant (P < .05) and negative relationship between BMI and the total number of normal-motile sperm cells. ANOVA revealed a significant difference (P < .05) in the total number of normal-motile sperm cells among the different BMI groups. The number of normal-motile sperm cells per BMI group was as follows: normal, 18.6 x 10(6); overweight, 3.6 x 10(6); and obese, (0.7) x 10(6). All multiple pairwise comparisons were found to be significantly (P < .05) different. The overall DFI mean (+/-SEM) was 24.7 (+/-2.57). Linear regression revealed a significant (P < .05) and positive relation between BMI and DFI. Men presenting with a BMI greater than 25 kg/m(2) have fewer chromatin-intact normal-motile sperm cells per ejaculate. Therefore, to ensure maximum fertility potential, patients may be advised to reduce body weight.
