Although nowadays most oocyte retrievals for in-vitro fertilization (IVF) are performed using a transvaginal, ultrasound-directed technique, monitoring of follicular development is still often performed via the abdominal route. On the bases of 106 sonographies carried out on 71 patients during ovulation monitoring within an IVF programme, we demonstrated that the number of follicles visualized endovaginally was significantly higher than that visualized by the abdominal route: n = 1124 versus n = 772 respectively, and that their size was significantly greater using the transvaginal approach: 20.8 mm versus 18.8 mm respectively, for the largest follicle. Consequently, if ovulation monitoring is carried out transvaginally, the follicular size criteria on which human chorionic gonadotrophin is administered must be reconsidered.
尽管如今大多数用于体外受精（IVF）的卵母细胞采集是通过经阴道超声引导技术进行的，但卵泡发育监测仍常常通过腹部途径进行。基于在一项IVF计划的排卵监测期间对71名患者进行的106次超声检查，我们证明经阴道可视化的卵泡数量明显高于经腹部途径可视化的卵泡数量：分别为n = 1124和n = 772，并且使用经阴道方法时卵泡大小明显更大：最大卵泡分别为20.8 mm和18.8 mm。因此，如果经阴道进行排卵监测，那么必须重新考虑给予人绒毛膜促性腺激素的卵泡大小标准。
