Abstract

Recent progress in female sterility of Japanese women is reported in this study. The causes of sterility in the female side, the most popular sterile factor is a tubal factor due to the increase of the endometriosis and pelvic inflammatory disease. The main treatment of the tubal factor is an IVF-ET technique. The ovulatory disturbances occupy the second position of the female sterile factor. The precise endocrinological examinations must be done for the diagnosis of the ovulatory disturbances. In case of the hypergonadotropic hypogonadism, the ovulation induction is almost impossible. Generally, clomiphene citrate is used for moderate hypothalamic anovulations, and bromocriptine or terguride is for prolactin related diseases (hyperprolactinemia, occult hyperprolactinemia, galactorrhea) and endocrinological PCO (LH/FSH > 1) in the beginning. If these treatments are not effective, hMG-hCG therapy will be performed. During hMG-hCG therapy, we must take care for the occurrence of the ovarian hyperstimulation syndrome. For the treatment toward the cervical factor, the artificial insemination with husband semen will be done, however, if it is not effective, IVF-ET must be performed. For the uterine factor (such as after hysterectomy state, adhesion of uterine cavity, etc.) surrogate mothers are hired in some foreign countries, however, it is prohibited in Japan. If patients have anti-phospholipid antibodies, low dose aspirin and/or heparin administration will be done for the treatment of infertility. Recently, the assisted reproductive technology (ART) have made much progress. IVF-ET is performed widely in Japan. Cryopreservation of the fertilized ovum and intracytoplasmic sperm injection (ICSI) are also performed. However, the legal and ethical problems are occurring, and much discussion must be done for the acceptance of such new technologies.

Does previous response to clomifene citrate influence the selection of gonadotropin dosage given in subsequent superovulation treatment cycles?

PURPOSE: To determine whether ovarian response to previous clomifene treatment could influence the selection of the starting dose of gonadotropins in subsequent in vitro fertilization (IVF) or intra uterine insemination (IUI). METHODS: Forty three anovular women who had received clomifene for ovulation induction followed by gonadotropins for IUI or IVF superovulation were reviewed retrospectively. Data on gonadotropin dose were compared between clomifene-resistant patients and clomifene responders. RESULTS: IVF patients who had had prior superovulation/IUI treatment received similar doses of gonadotropins regardless of response to clomifene (1610 IU versus 1560 IU, p = 0.74). In IVF patients not receiving prior IUI treatment, the clomifene-resistant women were given higher doses of gonadotropins than those responding to clomifene (2500 IU versus 1440 IU, p = 0.042). CONCLUSIONS: We found that, in our Unit, clinicians appeared to use prior non-response to clomifene as a reason for prescribing a higher starting dose of gonadotropins in IVF treatment, a practice that is not evidence-based.

The use of a decremental dose regimen in patients treated with a chronic low-dose step-up protocol for WHO Group II anovulation: a prospective randomized multicentre study.

BACKGROUND: In women with chronic anovulation, the choice of the FSH starting dose and the modality of subsequent dose adjustments are critical in controlling the risk of overstimulation. The aim of this prospective randomized study was to assess the efficacy and safety of a decremental FSH dose regimen applied once the leading follicle was 10-13 mm in diameter in women treated for WHO Group II anovulation according to a chronic low-dose (CLD; 75 IU FSH for 14 days with 37.5 IU increment) step-up protocol. METHODS: Two hundred and nine subfertile women were treated with recombinant human FSH (r-hFSH) (Gonal-f) for ovulation induction according to a CLD step-up regimen. When the leading follicle reached a diameter of 10-13 mm, 158 participants were randomized by means of a computer-generated list to receive either the same FSH dose required to achieve the threshold for follicular development (CLD regimen) or half of this FSH dose [sequential (SQ) regimen]. HCG was administered only if not more than three follicles >or=16 mm in diameter were present and/or serum estradiol (E(2)) values were <1200 pg/ml. The primary outcome measure was the number of follicles >or=16 mm in size at the time of hCG administration. RESULTS: Clinical characteristics and ovarian parameters at the time of randomization were similar in the two groups. Both CLD and SQ protocols achieved similar follicular growth as regards the total number of follicles and medium-sized or mature follicles (>/=16 mm: 1.5 +/- 0.9 versus 1.4 +/- 0.7, respectively). Furthermore, serum E(2) levels were equivalent in the two groups at the time of hCG administration (441 +/- 360 versus 425 +/- 480 pg/ml for CLD and SQ protocols, respectively). The rate of mono-follicular development was identical as well as the percentage of patients who ovulated and achieved pregnancy. CONCLUSIONS: The results show that the CLD step-up regimen for FSH administration is efficacious and safe for promoting mono-follicular ovulation in women with WHO Group II anovulation. This study confirms that maintaining the same FSH starting dose for 14 days before increasing the dose in step-up regimen is critical to adequately control the risk of over-response. Strict application of CLD regimen should be recommended in women with WHO Group II anovulation.
