  IMPLANTACIÓN REDUCIDA EN EMBRIONES CON DIVISIÓN DIRECTA MEDIANTE IMÁGENES TIME-LAPSE
La presencia del fenómeno de división directa en los embriones de una cohorte condiciona el potencial de implantación de dichos embriones. Mediante tecnología time-lapse es posible detectar este fenómeno y así evitar la transferencia de los embriones que la presentan.

  CONCENTRATION OF SEMINAL PLASMA ZINC IN VARIOUS CLASSES OF INFERTILE MALE
The present study was designed to analyze the level of seminal zinc among different groups of infertile males and to correlate it with sperm concentration, active, sluggish and immotile fractions of seminal parameters, with an objective being to establish the role of zinc. This descriptive analytical study was carried out in the Department of Reproductive Physiology/Health, Public Health Laboratories Division, National Institute of Health, Islamabad in a 5 years period from 2002 to 2006. The result showed that seminal zinc was 702.92 ± 10.60, 598.48 ± 12.95, 617.54 ± 9.55, 542.29 ± 22.75, 710.36 ± 7.87, 712.06 ± 7.96, 789.36 ± 21.33 and 762.06 ± 8.99 in azoospermic, oligozoospermic, asthenozoospermic, oligoasthenozoospermic, teratozoospermic, normozoospermic, polyzoospermic and proven fathers group, respectively. Findings of the study showed that semen zinc was several folds higher in polyzoospermic subjects as compared to other groups, while it was found to be lower in oligozoospermic, azoospermic and oligoasthenozoospermic groups. In case of proven fathers, the levels of semen zinc varied non significantly (p > 0.05) with polyzoospermic cases. It is concluded from the results of the study that decreased concentration of seminal plasma zinc affect sperm count while increased level causes decreased sperm motility.

  STUDENT'S KNOWLEDGE REGARDING AGE AND FERTILITY DECLINE
The findings demonstrate entrenched fertility myths among Israeli students, particularly the false belief in the possibility of late (beyond 35 years) and very late genetic motherhood. This can be explained by technological ‘hype’ and favorable media coverage of very late pregnancies. Since this may culminate in involuntary childlessness, it is highly important to increase the awareness of the Israeli public on the subject of fertility. However, as our sample is not representative of the Israeli student population, our findings should be tested in future studies.
