How is it performed?是如何表现呢？ of IVF对试管婴儿
The main IVF technique was developed in the 1970’s. This involves giving the woman fertility drugs to stimulate egg production, and then surgically retrieving the eggs from the ovaries. She is then given hormones to prepare her uterus for pregnancy, while the eggs are fertilised with the sperm in a laboratory. The embryos are then implanted into the woman’s uterus, and if all goes well a normal pregnancy is achieved.主要试管婴儿技术的发展，在1970â € ™美国这涉及到给该名女子的生育率药物，以刺激产蛋量，然后手术检索鸡蛋从卵巢，她是那么给予激素作好准备，她的子宫内怀孕，而鸡蛋是受精与精子在实验室里。胚胎，然后植入到womanâ € ™ s子宫，如果一切进展顺利的一正常妊娠的实现。
The Human Fertilisation and Embryology Authority's code of practice for clinics, states the number of embryo transfers should be limited to two for most women.人类受精和胚胎学管理局的业务守则的诊所，国家的数目胚胎转让应只限于两个，大部分是妇女。 However,women over 40, whose chances of a baby are smaller may have more than two embryos transfers.然而， 40岁以上的妇女，其机会一名女婴的是规模较小的可能有两个以上的胚胎转移。
IVF procedures developed more recently include Intra-cytoplasmic Sperm Injection (ICSI). This helps those men for whom the ‘standard’ IVF technique would fail, eg if their sperm are unable to penetrate the egg, to achieve pregnancy with their partner.试管婴儿的程序，开发更多，最近，包括内部的细胞质精子注射（ ICSI ） ，这有助于这些男子为谁â € 〜 standardâ € ™试管婴儿技术将失败，例如，如果他们的精子是无法穿透卵子，以达到怀孕与他们的合作伙伴。
Egg selection enables only the healthiest eggs to be taken from the ovaries for fertilisation. It can be useful for women with diminished number and quality of eggs. Procedures such as sperm washing can also be carried out to only retrieve sperm strong and healthy enough for inclusion in IVF techniques. This is particularly successful with men who have a low sperm count.蛋的选择，使只有最健康的卵子将要采取的从卵巢为受精，它可用于妇女与减少的数量和质量的鸡蛋。程序，如精子洗涤也可以进行只撷取精子稳固和健康的足够列入在试管内受精技术，这是特别成功的与男子谁拥有一个低税率的精子计数。
New assisted conception techniques are constantly being developed, and existing procedures refined. For example, 3D ultrasound can now be used to detect pre-pregnancy fertility problems, such as blocked fallopian tubes.新的辅助概念，技术正在不断发展，现有的程序完善。举例来说，三维超声，现在可以用来探测孕前生育问题，如输卵管阻塞。
