Many transgender men receive testosterone therapy to achieve virilization. The therapy is often mistaken for having a contraceptive effect because it causes amenorrhea. However, some treated patients become pregnant, which is not well known. A 25‐year‐old transgender man who had received testosterone for 3 years had an unplanned pregnancy during discontinuation of treatment. He was unaware of his pregnancy, resumed testosterone, and continued treatment until pregnancy was confirmed. His female child was exposed to androgens during the fetal period; thus, careful, long‐term observation was required. He developed insomnia and depression during the postpartum, and giving birth made it difficult for him to change his family register to male. Transgender men can become pregnant through sexual intercourse with biological men, even during hormone replacement therapy, so correct contraception is necessary to avoid unwanted pregnancies. Transgender sex education is important to increase awareness of this issue among individuals and medical professionals.
Purpose : It is essential to determine normative data of testicular size and penile length in newborn infants in order to assess the development during the fetal period. In this study, we evaluated testicular volumes using ultrasonography and also measured penile lengths in Japanese newborn infants. We also examined the associations of the development of these organs with factors including placental weight and anthropometric data. Methods : One hundred and fifteen full-term male newborn infants were recruited for this study. Testicular size was measured by ultrasonography. Results : Mean testicular volumes were 187.4 mm 3 in the right testis and 185.4 mm 3 in the left testis, and there was no significant difference between the right and left testicular volumes. Right and left testicular volumes showed positive and significant correlations with body lengths and weights. Testicular volumes in the right and left sides were not significantly associated with penile lengths. In 4 groups according to gestational weeks, testicular volume increased significantly with advance of gestational weeks in the left testis. Conclusion : We determined testicular volumes using ultrasonography in Japanese newborn infants. We believe that the results for newborn infants provide important information for assessment of the development of fetal testicular volume.
AimTo evaluate the usefulness of transabdominal sonographic confirmation of placental detachment in preventing uterine inversion.MethodsThis was 14‐year retrospective cohort study that included women who had transvaginal deliveries in our hospital. We introduced routine transabdominal ultrasonography during placental delivery to prevent uterine inversion. Followed by the confirmation of placental detachment by ultrasonography, we started placental delivery procedure. The frequency of uterine inversion during placental delivery was compared before and after the ultrasonography was introduced. Moreover, the duration of the third stage of labor and bleeding volume during labor were compared between the ultrasonography performing group (USG group) and the non‐performing group (non‐USG groups).ResultsFive thousand and eighty‐one women, including 1724 and 3357 women who delivered before and after the ultrasonography was introduced, respectively. The frequency of uterine inversion after the introduction of the ultrasonography system was significantly reduced compared to that before the introduction (0.03% vs. 0.23%, p = 0.03). Even after the introduction of ultrasonography, the actual rate of performing ultrasonography remained 54.1% due to various restrictions. The mean duration of the third stage of labor in the USG group was slightly longer than that in the non‐USG group (8.4 ± 5.0 vs. 6.8 ± 3.6, p < 0.01). The mean bleeding volume during labor in the USG group was higher compared with the non‐USG group (457 ± 329 vs. 418 ± 285, p < 0.01).ConclusionsTransabdominal sonographic confirmation of placental detachment may be useful in preventing uterine inversion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
