鼠类属Peromyscus(鹿鼠)是最普遍的原生北美的哺乳动物。 Peromyscus物种的研究范围广泛,包括毒物学,流行病学,生态,行为,和遗传研究。在这里,他们提供了一个有用的模型示范人工授精。





人工授精代替自然交配,以增加成功的机会,所有的女性会怀孕。用于每1超排的女性或在发情已知一名女2男。 caudae附睾成熟的雄性小鼠被放置在了9%的牛奶悬挂和切片18表针开放。精子被允许自由游泳几分钟,然后是附睾从混合物。悬架被评估为合流和活动精子的显微镜。钝的22号1 ½英寸长针是用来管理精子。 120 °弯曲放置约3 / 4 ,上下针方式。弯曲和0.025 - 0.05mls注射针插入阴道。如果一个助理是用来装的女性,在适当的位置,不需要使用麻醉药。


  1. 使用女6男4例
  2. 安乐死在男性的动植物公园
  3. 准备从9%的牛奶约5毫升奶粉
  4. 在小培养皿中放入1.5毫升
  5. 剪出epididymus和输精管
  6. 9%的牛奶在1.5毫升
  7. 使用两个18表针,并使用针长切割运动,切片打开epididymus和输精管释放精子
  8. 留过组织在显微镜下检查精子


  1. 使用120 °角的钝针
  2. 拿在手里的鼠标和注入的混合物。如果一个人持有和注射感到不舒服,两个人都可以使用。没有麻醉剂的使用,应在一个知道如何这可能会影响程序。
  3. 使用每个女性的精子/牛奶混合0.05毫升


  1. 对受援国的女性阴道涂片(此时收件人女性应在发情前期/发情)
  2. 都没有达到第5天发情女性可能不应该使用

  2. The total magnification to do the AI is between 10-²0x depending on the user for basic dissection. The sperm can be seen at 400x

  3. Hello Amanda!  Thank for this article. I d like if you can give me more information about the powered milk, and if there is any posibility of create "make in home" powered milk.

  4. Hi Carolina, The milk is a commercial powdered milk bought from a regular grocery store. I am not sure what it contains if you wanted to make it at home. A little less than 1 cm of the needle was inserted into the vagina for sperm delivery but if you want to test it...I would use a dead mouse to check the insertion length when making a new needle. Good luck Amanda

  5. Would there be any difference in the dimention of the insemination needle for rats. Is there a non-invasive method of extracting sperm in rats. How can the vaginal smear indicate prŒstrus/estrus.

  7. Amanda, Our lab is just beginning to look into artificial insemination.  After watching your video and looking at a few other artificial insemination protocols, I have a couple of questions: (1) How to you assess or induce ovulation? (²) How do you induce pseudopregnancy? Thank you, Rob

  8. Hola, respuesta para Robert Stiles, mira si tu problema es matar a los machos, lo que puedes hacer castrar a los animales, de esa manera no es necesario sacrificarlos. Por lo tanto puedes obtener los espermas necesarios sin sacrificar al animal.   Saludos desde México Roberto Lazzarini, Biologo experimental

  9. Hy Amanda, I would like to know  some things: 1 - what is your success rate? ² - Do you use the vaginal tampon like described by LECKIE et al, 1973 (Biology of Reproduction, Vol 9, 4²0-4²5)? 3 - I tested the techinique using dye solution and, afterwards, I sacrified the female, but I didn't see any solution inside the uterus. Do you introduce the needle in the cervix (like in human intra-uterine insemination) or you just put the needle very closely to it. Because don't have how to have sure about introducing into the cervix, unless using a special speculus. Thank you Daniela

  13. do you induce pseudopregnancy in the recipient female or do
    you literally just inject the donor sperm??
    If you induce how do you do this?
    What are the pregnancy rates like from using this AI?
