RESUMO
Adequate vitamin B(2), vitamin B(6), folate and vitamin B(12) nutrition is known to be important for reproductive function in women of childbearing age. The purpose of this study was to evaluate serum vitamin B(2), vitamin B(6), folate and vitamin B(12) status and serum homocysteine levels in 115 women aged 33.2 +/- 4.0 years, who had been diagnosed with infertility, and 49 women aged 34.5 +/- 3.8 years having at least one born child. Total vitamin B(2) and vitamin B(6) intakes in infertile women were significantly lower than those in control. Serum vitamin B(2), vitamin B(6), folate and vitamin B(12) concentrations were significantly lower in infertile women than those in control and serum homocysteine levels were significantly higher in infertile women than those in control. Thirteen percent in infertile women and zero percent in control were assessed as hyperhomocysteinemic and there was a significant difference in the prevalence of hyperhomocysteinemia between infertile women and control. 41% infertile women were assessed as folate deficiency. Serum folate concentrations was negatively correlated with serum homocysteine of the infertile women and control. Total vitamin B2 intakes was negatively correlated with serum homocysteine of the infertile women and control. Total vitamin B6, folate intakes were negatively correlated with homocysteine of infertile women only. In conclusion, infertile women are needed to intake more B vitamins intakes. Furthermore researches are needed to estimate adequate B vitamin supplementation in infertile women.

Pulsatile secretion of GnRH from the hypothalamus is a prerequisite for both the initiation and maintenance of the reproductive axis in humans. Failure of this episodic GnRH secretion results in the clinical syndrome of hypogonadotropic hypogonadism. Deficient GnRH secretion may occur in isolation (idiopathic hypogonadotropic hypogonadism: IHH), in association with anosmia (Kallmann syndrome), or as a result of a variety of structural and functional lesions of the hypothalamic pituitary axis. The familial occurrence of hypogonadotropic hypogonadism associated with anosmia, color blindness, synkinesia, and mental defect is the classic Kallmann syndrome. Affected individuals respond readily to pulsatile administration of exogenous GnRH, and clearly this is the most physiologic approach to ovulation induction. For women not seeking pregnancy, replacement therapy with exogenous estrogen and progestin is indicated. We have experienced a case of Kallmann syndrome which was conceived by administration of gonadotropin. So we report this case with a brief review of literatures.

OBJETIVE: To analyze the antithrombin III deficiency in patients with recurrent spontaneous abortion. MATERIALS AND METHOD: The blood samples were tested by chromogenic assay to evaluate the activity of antithrombin III. RESULTS: There was only one case of antithrombin III deficiency. This patient experienced one neonatal death after delivery and one FDIU (fetal death in utero). And also this patient showed a lupus anticoagulant and the prolongation of PTT. CONCLUSIONS: Women with recurrent miscarriage who have no obvious identified cause should consider hematologic screening. Antithrombin III deficiency could be a cause of recurrent spontaneous abortion. But the incidence is very rare in Korean patients.

OBJECTIVE: To evaluate the abnormality of protein S in patients with recurrent spontaneous abortion due to antiphospholipid syndrome. MATERIALS AND METHOD: Antigen and activity of protein S were analyzed by enzyme immunoassay and clotting method, respectively. RESULTS: Of 18 patients with antiphospholipid syndrome, 4 patients were found to have no abnormality of protein S. There were 14 cases of protein S abnormality. Among them, there were 8 cases of type 1, 1 case of type 2, and 5 cases of type 3 protein S deficiency. CONCLUSION: So in the workup of patients with recurrent spontaneous abortion due to antiphospholipid syndrome, the evaluation for protein S is required.

OBJECTIVE: To analyze the clinical characteristics of obese infertile women. MATERIAL AND METHOD: Height, weight, body mass index, menstrual pattern, glucose, insulin, glucose / insulin ratio, dehydroepiandrosterone sulfate (DHEA-S), testosterone, free testosterone and plasminogen activator inhibitor (PAI-1) of 15 obese infertile women were tested. RESULTS: Of 15 obese infertile women, the number of diabetes mellitus, hyperinsulinemia, and insulin resistance was 2 (13%), 2 (13%), 2 (13%), respectively. The incidence of increased DHEA-S, testosterone, and free testosterone was 7 (47%), 1 (7%), 6 (40%), respectively. Notably, all patients showed increased PAI-1. CONCLUSIONS: Obesity is associated with infertility as well as many kinds of health problems. Obesity is closely related to insulin resistance and it also causes hyperandrogenism. Increased PAI-1 is one of the important causes of thrombophilia. Consequently, in the workup of obese infertile patient, many aspects of health problems should be considered.

OBJECTIVE: To analyze the interrelationship between homocysteine and methylenetetrahydrofolate reductase (MTHFR) mutation in patients with recurrent spontaneous abortion. MATERIAL AND METHOD: Homocysteine and MTHFR mutation were tested by fluorescent polarizing immunoassay and PCR-RFLP method, respectively. RESULTS: In patients with homocysteine level less than 5 mmol/L, there was no case of normal group but there were four cases of heterozygosity and one case of homozygosity. In patients with homocysteine level 5~10 mmol/L, the number of normal, heterozygosity and homozygosity group were eleven, eighteen and eight, respectively. In patients with homocysteine level 10~15 mmol/L, the number of normal, heterozygosity and homozygosity group were four, one and one, respectively. In patients with homocysteine level more than 15 mmol/L, there was no case of normal and heterozygosity group but there were two cases of homozygosity. CONCLUSIONS: Hyperhomocysteinemia due to MTHFR mutation is a cause of recurrent spontaneous abortion. And there was a significant relationship between homocysteine and MTHFR mutation.

OBJECTIVE: To report the pedigree of Kallmann syndrome inherited in autosomal dominant mode with variable expressivity. MATERIAL AND METHOD: Case report. RESULTS: The patient had amenorrhea and anosmia but did not have a sign of absolute hypogonadotropic hypogonadism. Her father had an anosmia and her two elderly sisters also had an anosmia but delivered babies uneventfully. Her two male siblings did not show any signs of hypogonadotropic hypogonadism. CONCLUSION: Kallmann syndrome has many different modes of inheritance such as autosomal dominant, autosomal recessive, and X-linked form. So the careful investigation of family pedigree is required.

A balanced translocation in a parent may produce unbalanced gametes leading to abortions or defective liveborn children, or interval infertility. It also may give rise to a balanced gamete resulting in a balanced carrier, or it may produce a cytogenetically normal gamete. The incidence of balanced chromosomal translocations in couples with multiple abortions was reported as 0% to 31%. This wide variation is related to the heterogeneous criteria used for patient selection. Because parents with balanced chromosomal rearrangements and history of only repeated abortions have a significant chance with each pregnancy of having a child with normal or balanced karyotype, the usual criteria for investigation include at least two abortions or reproductive losses. There is no evidence from several reported series that increasing the number of losses to three or more leads to any change in the yield of chromosomal rearrangements detected.

Toxoplasma gondii, an intracellular coccidian protozoan, is the causative agent of toxoplasmosis, a widespread infection affecting various birds and mammals including humans. In immunocompetent hosts, the infection is usually asymptomatic and benign. Toxoplasmosis is either congenital or acquired. In general prenatal therapy of congenital toxoplasmosis is beneficial in reducing the ncy of infant infection. Therapies are based primarily on spiramycin because of the relative lack of toxicity and high concentration achieved in the placenta. Clindamycin is the standard drug for chemoprophylaxis in newborn infants, and is directed at preventing the occurrence of retinochoroiditis as a late sequel to congenital infection. The standard treatment for acquired toxoplasmosis in both immunocompetent and immunodeficient patients is the synergistic combination of pyrimethamine and sulphonamides. Toxoplasmic encephalitis is tbe most common manifestation of acquired toxoplasmosis in immunocompromised patients and if not treated is fatal. However, because of toxicity, the therapeutic efficacy of pyrimethamine sulphonamide combinations may be seriously limited in immunodeficient patients. We have experienced a case of toxoplasmosis during the workup of habitual aborter. So we report this case with a brief review of literatures.

Polycystic ovary disease is a heterogenous endocrinopathy with many interacting causal factors. One potential such factor is chronic hyperinsulinemia. multiple, independent lines of evidence suppart the contention that chronic hyperinsulinemia causes ovarian hyperandragenism. This evidence includes: (1) mutations in the insulin receptor gene that cause severe hyperinsulinemia appear to be associated with ovarian hyperandrogenism, (2) insulin stimulates ovarian thecal and sttomal androgen seaetion in vitro, and (3) in some experimental models, manipulation of circulating insulin concentrations results in changes in circulating androgens. Although the association between hyperinsulinemia and hyperandrogenism remains to be fully explained at the molecular level, chronic hyperinsulinemia appears to be an important cause of hyperandrogenism. We have experienced a case of HAIR AN syndrome showing hyperandrogenism, insulin resistance and acanthosis nigricans in infertile patient. So we report this case with a brief review of literatures.

OBJECTIVE: To report the prevalence of lupus anticoagulants and anticardiolipin antibodies in patients with recurrent spontaneous abortion and infertility. MATERIAL AND METHOD: Lupus anticoagulants and anticardiolipin antibodies were analyzed by Diluted Russell's Viper Venom Test (DRVVT) and solid phase enzyme immunoassay, respectively. RESULTS: In 200 patients with infertility, there were 6 cases (3%) with positive lupus anticoagulants or anticardiolipin antibodies. Of these, 3 patients (1.5%) showed positive lupus anticoagulants and anticardiolipin antibodies, respectively. In 120 patients with recurrent spontaneous abortion, there were 13 cases (10.8%) of positive lupus anticoagulants or anticardiolipin antibodies. Of these, one patient (1%) showed lupus anticoagulants and 12 patients (10%) showed anticardiolipin antibodies. But in two groups, there was no cases with positive lupus anticoagulants and anticardiolipin antibodies. CONCLUSION: Lupus anticoagulants and anticardiolipin antibodies are definite cause of recurrent spontaneous abortion. There has been a speculation that they might be associated with infertility and repeated IVF failures. But it was found that the role of lupus anticoagulants and anticardiolipin antibodies in these cases are not clear.

OBJECTIVE: To evaluate factor XII deficiency in patients with recurrent spontaneous abortion and its relation to aPTT. MATERIAL AND METHOD: Factor XII was analyzed by clotting method. RESULTS: Of 70 patients with recurrent spontaneous abortion, there were 35 cases of factor XII deficiency. Among them, there were only 3 cases of prolonged aPTT. CONCLUSIONS: It is still unclear whether factor XII deficiency is related to recurrent spontaneous abortion. Molecular approaches should be used to understand further the causal relationship. But based on this result, in the workup of patients with recurrent spontaneous abortion, factor XII should be included. aPTT is not likely to represent the abnormality of factor XII.

Monozygotic twinning is a relatively rare event in vivo conception, being estimated to occur in 0.42% of all birth. The underlying mechanism for monozygotic twin formation is the division of the embryo early in its development. Separation of cells may theoretically occur before or after inner cell mass formation. The incidence of monozygotic twinning following assisted reproduction techniques is higher than the commonly accepted incidence after in vivo conception. Patients at particular risk of monozygotic twins are those aged > 35 years and those who had manipulation techniques for assisted fertilization. Hence, it seems prudent to counsel these patients about the potential obstetric complications of monozygotic multiple gestations prior to the initiation of their treatment.

The mullerian ducts join the sinovaginal bulb at a point known as the mullerian tubercle. Canalization of the mullerian tubercle and sinovaginal bulb is necessary to give a normal vaginal lumen. If the area of junction between these structures is not completely canalized, a transverse vaginal septum will occur. This may be partial or complete and generally lies at the junction of the upper third and lower two thirds of the vagina. It occurs in about 1 per 75,000 females. Partial transverse vaginal septa have been reported in diethylstilbestrol (DES)-exposed females. In the prepubertal state, diagnosis is generally not made unless there is the development of a mucocolpos or mucometrium behind the septum. At puberty, however, if the septum is complete, hematocolpos and hematometrium may occur in a fashion similar to that seen in the imperforate hymen, except that there is no bulging at the introitus. The patient with an incomplete transverse septum may bleed somewhat but will still develop hematocolpos and hematometrium over time and may also complain of foul smelling vaginal discharge.

Systemic lupus erythematosus(SLE) is a multisystem disorder with a peak age of onset in the second and fourth decades of life predominantly occuring in females who will usually have the potential to become pregnant. This female to male predominance is greatest during childbearing years approaching a ratio of 13:1, after the menopause it declines to a ratio of 3:1, the ratio also seen in prepubertal years. In practice, despite the higher prevalence of rheumatiod arthritis, pregnancy in SLE is the most common management problem confronting physician and obstetrician amongst the connective tissue disorders and it is particularly important as the outcome of pregnancy is more unpredictable in this disease. As well as having clinical consequences for the health of both mother and fetus, pregnancy in lupus provides a model for studying the importance of other biological phenomena characterizing the disease. For example, the transplacental passage of maternal antibodies to Ro(SSA) and La(SSB) and their strong association with the neonatal lupus syndrome suggests a pathogenetic role for these autoantibodies. Other relevant issues are feto-meternal immunological tolerance and hormonal interaction with the immune system. We have experienced a case of recurrent pregnancy loss associated with systemic lupus erythematosus. So we report this case with a brief review of literatures.

Prenature ovarian failure is a condition causing amenarrhea, hypoestrogenism, and elevated genadotropins in women younger than 40 years. A karyotype should be performed as part of basic laboratory evaluation for all patients with premature ovarian failure and prodromal premature ovarian failure. Development of a malignancy in a dysgenetic gonad is of major concern. The presence of a fragment of the Y chromosome is thought to be a key to the oncogenic potential of these gonads. The search for the testicular determining factor(TDF) has engendered much confusion about which part of the Y chromosome plays a role in malignancy. This was initially postulated to be the H- Y antigen. More recent data, however, localize the area near the centromere of the Y Chromosome, on the long arm(Yq). Malignant potential is clearly not linked to the testicular determining factor itself(SRY). This is a critical point in clinical medicine. Feilure to display SRY or a closely related sequence does not rule out the presence of the segment of the Y chromosome postulated to be associated with the development of malignancies. We have experienced a case of premature ovarian failure with chtomosomal abnormality involving Y chromosome fragment. So we report this case with a brief review of literatures.

OBJECTIVE: Previous studies have suggested that hyperhomocysteinemia and methylenetetrahydrofolate reductase (MTHFR C677T) mutations are associated with increased risk of recurrent spontaneous abortion (RSA). Recently, a second site polymorphism in MTHFR, 1298A-->C, which changes a glutamic acid into an alanine residue, was shown to be associated with a decreased enzyme activity. We tested whether the variant alleles of MTHFR C677T and A1298C are risk factor (biomarker) for RSA. MATERIALS AND METHODS: We analyzed DNA from a case-control study in the Korean DNA was extracted from blood samples of 118 patients with RSA and 123 healthy fertile patients as the controls. MTHFR variant alleles were determined by a PCR-restriction fragment length polymorphism assay. RESULTS: We found no evidence for an association between 677TT genotype and risk of RSA (OR=1.95, 95% CI=0.84~4.50, p=0.12). However, the MTHFR 1298AC (OR=0.36, 95% CI=0.20~ 0.63, p=0.0004) and 1298AC+CC (OR=0.35, 95% CI=0.20~0.61, p=0.0002) genotypes were lower among 118 RSA cases compared with 123 controls, conferring a 2.8-fold decrease in risk of RSA, respectively. Moreover, the combined genotypes of MTHFR 677CC/1298AC (OR=0.30, 95% CI= 0.10~0.88, p=0.029) and 677CT/1298AC (OR=0.77, 95% CI=0.60~0.99, p=0.043) also showed significantly lower risk than those with MTHFR 677CC/1298AA type. CONCLUSION: MTHFR 1298AC, MTHFR 677CC/1298AC and 677CT/1298AC genotypes may represent genetic markers for the protection of RSA at least in Korean women.
