試管嬰兒 (IVF) 的流程 < 費用約 10~15 萬 > Flow chart for In Vitro Fertilization (IVF) <About NT$ 100,000~150,000> 誘導排卵 : 進入月經週期之後, 利用排卵藥物, 刺激卵巢產生較多的卵泡排卵藥物 : GnRH Gonal-F HMG LH Stimulate ovulation: Within the menstrual cycle, use ovulatory drugs to stimulate the ovary to produce more ovarian follicles. Ovulatory drug: GnRH Gonal-F HMG LH 追蹤卵泡之成熟度 : 藉助超音波偵測儀, 定期的監測卵泡發育的情形, 並抽血檢驗追蹤血液中動情激素的數值變化, 以決定何時取卵是最佳的時機 Monitor the maturity of the ovarian follicles: Monitor the development status of the ovarian follicles regularly with ultrasound, sample the blood to test and monitor the estrogen hormone in order to determine the optimal time for oocytes retrieval. 采卵前 36 小時, 要注射人類絨毛膜性腺激素 hcg 以準備采卵作業 36 hours before oocytes retrieval, as a preparation, injection of Human Chorionic Gonadotropin (hcg) is necessary. 取卵 : 采全身麻醉, 在陰道超音波的導引下取出卵子, 手術所需時間很短, 術後沒有傷口, 不必住院 Ovum retrieval: Under general anaesthesia, retrieve the oocytes with the guidance of trans-vaginal ultrasound. The operation lasts only a short time without invasive cuts and hospitalization

取精 : 取卵當天上午請先生取精, 如需手術取精者, 請事先告知泌尿科醫師 Semen retrieval: obtain the husband's semen on the same day of oocytes retrieval. If the semen retrieval requires operation, please inform the urologists in advance. 體外授精 : 取出的卵泡液直接送入實驗室處理, 再將卵子篩選出來而先生的精液經過洗滌篩選處理後, 與太太的卵子經過 2~5 天的培養精子條件欠佳者, 可做單一精蟲顯微注射 (ICSI) In vitro fertilization: Send the obtained ovarian follicles to the laboratory for selection, and then choose the best quality oocytes. If the husband s sperm, after washed and purified, seems not quite good after 2~5days cultivation with the wife s ovum, Intracytoplasmic Sperm Injection (ICSI) can be applied. 胚胎植入 : 受精卵發育成為成熟的胚胎, 再將胚胎植入輸卵管或子宮腔內 Embryo Transfer: after the fertilized oocyte develops to mature embryo, transfer the embryo into the fallopian tube or uterus. 協助孵化 : 胚胎外殼透明層打洞説明著床 Assisted hatching: drill the outer layer (zona pellucida) of the embryo for embedding. 多餘的胚胎冷凍 Freeze the extra embryos 補充黃體素, 兩周後驗孕 Progesterone supplement. Perform pregnancy test two weeks later.

驗追蹤血液中動情激素的數值變化, 以決定何時取卵是最佳的時機 Generally speaking, during the whole process of test-tube baby, the wife must receive Gonadotropin Releasing Hormone analog (GnRHa) on the 21st day of the previous menstrual cycle, which can block the stimulation of hypothalamus on the pituitary, so that it can not excrete gonadotropin. After 14~18 days treatment when a new menstrual cycle begins, use ovulatory drugs to stimulate the ovary to product more ovarian follicles. At the same time, monitor the development status of the ovarian follicles regularly with trans-vaginal ultrasound and monitor the serum estrogen hormone level in order to determine the optimal time for oocytes retrieval. 而卵巢中最小的卵泡直徑只有 0.1~0.2mm 大小, 稱為原始卵母細胞, 月經初期卵泡直徑約 5mm 大小, 卵泡的生長情形, 會受到卵泡刺激激素 (Follicle Stimulation Hormone, FSH) 的作用, 讓卵泡繼續生長到約 8mm 大小, 動情激素就開始增加分泌, 當卵泡直徑增加到 15mm 大小時, 動情激素的分泌更為亢進, 大量的動情激素會促使腦下腺釋放出黃體刺激激素 (Luteinizing Hormone, LH), 以促使卵泡表面的部份組織變薄, 然後在采卵前 36 小時, 須提醒病人要注射人類絨毛膜性腺刺激素 (Human chorionic gonadotropin, hcg), 以準備采卵作業 The minimum ovarian follicles in the ovary is only 0.1~0.2mm in diameter, and is called as primordial oocyte. In the Menstrual phase, the diameter of the ovarian follicle is 5mm. The development of the ovarian follicle will be influenced by Follicle Stimulation Hormone (FSH). Till the ovarian follicle grows to 8mm in diameter, the estrogen hormone will be excreted. When the follicle grows to 15mm in diameter, the excretion of estrogen hormone is over active, and the enormous estrogen hormone will stimulate the pituitary to release Luteinizing Hormone (LH), which can help to thin the partial organs on the surface of ovarian follicle. 36 hours before the ovum retrieval, it is important to remind the patient to inject Human chorionic gonadotropin (hcg) as a preparation for oocytes retrieval. 采卵當天以陰道超音波導引下施行采卵, 取出的卵泡液直接送入實驗室處理, 再將卵子篩選出來, 放置到另一個新的培養皿內而先生的精液經過洗滌篩選處理後, 與太太的卵子經過 2~5 天的培養, 受精卵發育成為成熟的胚胎, 再將胚胎植入太太的輸卵管或子宮腔內通常黃體刺激激素在刺激排卵之後, 仍殘留在卵泡壁上的顆粒細胞與內膜細胞, 使之變成黃

體細胞, 黃體會分泌大量的黃體激素 (Progesterone, P4), 以利於胚胎的著床 On the very day, with the guidance of trans-vaginal ultrasound, oocytes are retrieved. Send the obtained ovarian follicles to the laboratory for treatment, and then select the good quality oocytes and place them on a new cultivate dish. The husband s sperm, after washed and purified, is applied to cultivate with the wife s oocytes for 2~5days. After the fertilized oocyte develops to mature embryo, transfer the embryo into the fallopian tube or uterus cavity. Generally, after stimulating the ovulation, the luteotropic hormone will still remain on the granular cells and endometrial cells to change them into corpus luteal cells. The corpus luteum will excrete enormous Progesterone, which is helpful for embedding. 一般試管嬰兒植入術, 其施行植入的方式可以分為 : Generally, the method for In Vitro Fertilization include: ( 一 ) 體外受精 / 胚胎植入術 (In-Vitro Fertilization/Embryo Transfer, IVF/ ET) 先生的精液經過洗滌篩選後, 直接在胚胎培養室與卵子進行體外培養, 經受精作用後, 受精卵培養到 48 小時以上, 發展到 2 個以上的細胞期 ( 包括 :4 個細胞期,8 個細胞期, 桑椹期或囊胚期, 分別有第 2,3,4 天植入和第 5 天植入等不同時間, 依病人臨床狀況需要決定 )( 圖 1-20, 圖 1-21, 圖 1-22, 圖 1-23, 圖 1-24), 胚胎再經過陰道及子宮頸, 將其植入子宮腔內, 適合於兩側輸卵管皆阻塞或粘黏的婦女, 或是經過多次人工授精失敗的不孕婦女, 都適合做體外受精 / 胚胎植入術 After washed and purified, the husband s semen is directly cultivated with the oocyes in vitro in the Embryo Cultivation Room. After fertilized, the fertilized oocyte is cultivated for more than 48 hours till it develops into over two-cell stage, including four-cell ovum stage, eight-cell stage, morula stage, and blastula stage, which requires transfer respectively on the 2nd, 3rd, 4th, and 5th day according o the clinic status of the patients (see Figure 1-20, 1-21, 1-22, 1-23, and 1-24). Then, through the vagina and cervix, the embryo is transfer into the uterus cavity. IVF/ET is applicable to women whose fallopian tubes

are both obstructed, or who suffers from infertility after several failure in artificial insemination. 圖 Figure 1 二前核期 (Two-Pronuclear phase, 2PN) 圖 Figure 2 胚胎發育進入 2 個細胞期 (Two-cell phase) 圖 Figure 3 胚胎發育進入 4 個細胞期 (Four-cell phase) 圖 Figure 4 胚胎發育進入 8 個細胞期 (Eight-cell phase) 圖 Figure 5 胚胎發育進入桑椹期 (Morula phase) 圖 Figure 6 胚胎發育進入囊胚期 (Blastula stage)
