在辅助孵化，然后将其转移到子宫中的激光用于受精卵的薄的透明带（外壳）。 This outer shell is believed to become thicker and hardened with aging of the oocyte (egg).
女性年事已高，或在第三天的促卵泡激素增高（FSH）水平，可能对胚胎着床的机会降低。 The embryos of women with endometriosis and poor quality embryos may also have this problem. The assisted hatching technique was introduced to enhance the embryos' ability to hatch, and thus implant, after transfer.
囊胚培养是发展胚胎超越文化的第三天的技术。 Typically with IVF, embryos are transferred into the uterus about three days after the egg retrieval. On the third day, embryos generally are between six to eight cells. Over the years, improved culture environments have allowed us to culture the embryos two additional days. During this additional culture period, the embryos continue to grow to become "blastocysts."
胚胎发育的自然过程开始于在输卵管的外方面卵子的受精。 As the newly formed embryo develops, it moves slowly toward the uterine cavity where it will ultimately implant. This process takes approximately six to seven days. When the embryo reaches the "blastocyst" stage, it is ready to implant.
在某些患者中，胚泡培养bob彩票vip投注允许胚胎用于转移的最佳选择，导致增加的植入率每胚转移。 However, it is important to understand that this technology may not necessarily increase your chance for pregnancy. The main advantage is that fewer embryos may be transferred to eliminate the possibility of multiple pregnancies, while maintaining a high pregnancy rate.
一般来说，这个过程应该仅限于患者的胚胎数量过多 - 超过五 - 在这种情况下超越了天胚胎的进一步选择三级将是有利bob彩票vip投注的。 As a general rule, patients under age 37 are candidates for this culturing technique.
对于年轻患者，所有的胚胎bob彩票vip投注高达50％将继续增长到囊胚阶段。 However, 10 percent of patients won't have an opportunity for embryo transfer due to the absence of blastocyst development. As patients get older, fewer and fewer numbers of embryos are capable of developing in culture to the blastocyst stage.
胚胎共培养是用他们转移到母亲的子宫前位，提高胚胎的整体质量的技术。 It was initiated in the UCSF IVF Laboratory, but several other IVF programs in the world have used this technique since 1996. Co-culturing uses human granulosa or endometrial cells that may secrete nutritional products that help growing embryos improve their chances for survival.
采用共培养，我们所看到的取卵后72小时胚胎质量和相对生长的改善。 Eggs fertilize within 18 to 24 hours after egg retrieval.
我们只建议技术谁在加州大学旧金山分校或与其他程序已经与胚胎质量较差以前不bob彩票vip投注成功的IVF周期，无论是这里的病人。 We do not recommend it to patients who have never been through IVF before, or who have had treatment cycles with excellent embryo quality in the past.
要了解的一个重要概念是，你实现怀孕，不论你的年龄的可能性，取决于你的胚胎的整体素质。 If you have generally good embryo quality, then you have a higher chance of conceiving from your IVF treatment cycle. Conversely, if you have generally poor embryo quality, then your chance for success diminishes.
与联合培养相关的风险是未知在这个时候。 Because it has never been tested extensively, there is no information regarding children born of co-culture using these specific cells. Because of this fact, we remain cautious about using this technique on patients who clearly may not benefit from it. It is important to understand that some patients may not have improved embryo quality, despite the use of co-culturing.
如果你和你的医生同意使用共培养的试管婴儿治疗周期，那么我们会在孵化共培养环境，所有的胚胎，只要我们的胚胎学家确认施肥。 We will continue co-culture until the day of your embryo transfer.
这是可能冻结共培养胚胎。 Co-culture will not affect the ability of your embryos to freeze well. We use the same standards for freezing co-cultured embryos as we do for standard cultured embryos. If your embryo quality is improved with co-culture, there is a greater likelihood that we will be able to freeze more embryos for you.
