Abstract
Background: The purpose of the current study was comparing pregnancy outcomes for natural cycle in vitro fertilization (IVF) per fresh embryo transfer (ET) and oocyte pick-up (OPU) in intrauterine insemination (IUI). Methods: This was a retrospective cohort study of women who underwent either IUI (n=246) or OPU with fresh ET for natural cycle IVF (n=291), conducted between April 2017 and February 2018 at the Center for Reproductive Medicine and Implantation Research, Sugiyama Clinic Shinjuku, Tokyo, Japan. Patients in both groups did not receive ovarian stimulation and luteal support; gonadotropin-releasing agonist spray was administered 35 hr before OPU or IUI. The clinical pregnancy rate was compared between the IUI and IVF groups. Data analysis was based on the number of cycles. The p≦0.05 was considered significant. Results: The clinical pregnancy rate per OPU in the IVF group was higher than the one in IUI group (20.6% vs. 10.1%), and the difference was significant (p<0.01). The pregnancy rate for natural cycle IVF calculated per fresh ET was 36.8%. The miscarriage rate did not significantly differ between the IVF (4.1%) and IUI (8.0%) groups. Conclusion: Fresh ET in natural cycle IVF provides a higher implantation rate than IUI.

Effects of Periconceptional Multivitamin Supplementation on Folate and Homocysteine Levels Depending on Genetic Variants of Methyltetrahydrofolate Reductase in Infertile Japanese Women. Nutrients 2021; 13:nu13041381.

Abstract
Methylenetetrahydrofolate reductase (MTHFR) has various polymorphisms, and the effects of periconceptional folic acid supplementation for decreasing neural tube defects (NTDs) risk differ depending on the genotypes. This study analyzed the effectiveness of multivitamin supplementation on folate insufficiency and hyperhomocysteinemia, depending on MTHFR polymorphisms. Of 205 women, 72 (35.1%), 100 (48.8%) and 33 (16.1%) had MTHFR CC, CT and TT, respectively. Serum folate and homocysteine levels in women with homozygous mutant TT were significantly lower and higher, respectively, than those in women with CC and CT. In 54 women (26.3% of all women) with a risk of NTDs, multivitamin supplementation containing folic acid and vitamin D for one month increased folate level (5.8 ± 0.9 to 19.2 ± 4.0 ng/mL, p < 0.0001) and decreased the homocysteine level (8.2 ± 3.1 to 5.8 ± 0.8 nmol/mL, p < 0.0001) to minimize the risk of NTDs in all women, regardless of MTHFR genotype. Regardless of MTHFR genotype, multivitamin supplements could control folate and homocysteine levels. Tests for folate and homocysteine levels and optimal multivitamin supplementation in women with risk of NTDs one month or more before pregnancy should be recommended to women who are planning a pregnancy.

Abstract
This study aimed to examine the incidence of hypertensive disorders of pregnancy (HDP) among Japanese women with oocyte donation pregnancy (ODP) aged 40 years or older and estimate whether the women with ODP were more likely to develop HDP than those with autologous oocyte pregnancy (AOP) and spontaneous pregnancy (SP). In our study (N = 1361), the proportions of women who developed HDP were 20.5%, 12.8%, and 7.6% for ODP, AOP, and SP, respectively. After adjustment of covariables, the women with ODP were more likely to develop HDP than those with AOP or SP.
