In vitro maturation of immature human oocytes in culture medium containing follicular fluid

Abstract: In clinical IVF programs often immature oocytes are retrieved. Under such circumstances, numerous workers have advocated the procedure of pre-incubation in insemination medium for 12-36 hours, prior to insemination to induce maturation. We describe here the supplementation of follicular fluid in insemination medium to induce maturation of immature oocytes. The culture characteristics of the insemination medium containing follicular fluid appears to be better than the insemination medium without follicular fluid. Previous reports suggest the presence of a meiosis-inducing substance in follicular fluid which could trigger the resumption of meiosis and hence contribute to oocyte maturation. Other factors in follicular fluids which are yet to be elucidated, may also contribute to oocyte maturation. It is concluded that superior culture characteristics can be obtained if immature oocytes are preincubated for 16-36 hours in insemination medium containing 50% follicular fluid.

Maternal reciprocal translocation t(1p;6p) in a couple with recurrent spontaneous abortion
Item Type: Article

Abstract: G-banded chromosome complements were analyzed from peripheral blood lymphocytes of a couple who had experinced for spontaneous abortions. The karyotype of the husband was designated as 46,XY, while the wife's karyotype was designated as 46,XX, t(1p;6p). Balanced reciprocal translocations appear to be associated with the recurrent spontaneous abortions experienced by the couple. We report here a case of a maternal (1p;6p) reciprocal translocation in a couple with repeated fetal loss.

A prospective study of the acceptability of today vaginal contraceptive sponge among Malaysian women
Item Type: Article

Abstract: Fifty volunteers were selected in a two month prospective study to evaluate the acceptability of the Today vaginal sponge contraceptive among Malaysian women. One participant developed allergic reaction to the sponge and was taken off at an early stage of the study. Fourty- nine participants completed one month follow-up.Thirteen subjects discontinued for various reasons which are related and not related to the sponge. The remaining 36 participants completed the study. Few side effects were observed among the sponge users who completed the trial. One subject complained that the Loop of the sponge hurt her husband's penis. Most of the women who are on the sponges claimed that sexual intercourse is no longer messy. Four subjects claimed that the sponges pontentiated sexual feeling to their male partners. The sponge is generally accepted by the study group, which suggest that the general impression 'Asian Women abhor any form of vaginal contraception' is not totally correct. It is suggested that the contraceptive efficacy of the sponge be evaluated among our women in the future.
