To study the potential benefit of testicular sperm compared with ejaculated sperm for men with oligospermia. After exemption from institutional review board approval, we performed a retrospective cohort study using the Mayo Clinic Assisted Reproductive Technology database. Single academic center. Couples with nonazoospermic male factor infertility (total motile sperm <25 million per ejaculate) undergoing intracytoplasmic sperm injection with sperm obtained by testicular sperm extraction (TESE) or ejaculated sperm between 2016 and2019. Invitro fertilization, Intracytoplasmic sperm injection, TESE. The primary outcome was live birth rate. The secondary outcomes were fertilization rate, blastulation rate, pregnancy rate, and miscarriage rate. Subjects in the two groups were similar in age, body mass index, and ovarian reserve. Baseline sperm parameters were similar in the two groups total motile sperm (5.4 in the ejaculate sperm group vs. 3.6 million motile per ejaculate), except that baseline motility was higher in the group that used ejaculated sperm (40% vs. 29%). The total number of mature oocytes retrieved was similar in the two groups, but the use of TESE was associated with a 20% decrease in fertilization (60.0% vs. 80.6%) and half the number of blastocyst embryos (two vs. four) compared with ejaculated sperm. Compared with ejaculated sperm, use of TESE did not improve the miscarriage rate (11% vs. 9%) or the live birth rate (50.0% vs. 31.3%). Patients with male factor infertility and oligozoospermia did not have improved ICSI outcomes with the use of TESE samples compared with ejaculated sperm. Patients with male factor infertility and oligozoospermia did not have improved ICSI outcomes with the use of TESE samples compared with ejaculated sperm. To describe techniques for resection of a cornual heterotopic pregnancy. This video demonstrates a surgical technique for excision of a cornual heterotopic pregnancy with narrative video footage using two case examples. The incidence of cornual heterotopic pregnancy is unknown; however, the incidence of heterotopic pregnancy itself has increased through the use of assisted reproductive technologies and the majority of cornual heterotopic pregnancies occur after assisted reproductive technologies use. These cases have been treated traditionally using exploratory laparotomy and cornual wedge resection with good outcomes. With advancements in minimally-invasive surgical techniques, laparoscopic resection of cornual heterotopic pregnancies has been demonstrated to be safe and feasible. A patient with an 8-week cornual heterotopic pregnancy and a patient with a 10-week cornual ectopic pregnancy. Laparoscopic resection of the cornual ectopic pregnancy. Feasibility of a "purse-string" technique for the rechnique. This technique allows for minimal blood loss in cases where additional techniques for hemostasis cannot be used, such as injection of vasopressin and uterine artery ligation.In patients after Fontan completion exercise capacity is significantly reduced. Although peak oxygen consumption (VO2peak) is a strong prognostic factor in many cardiovascular diseases, it requires the achievement of a maximal effort. Therefore, submaximal exercise parameters such as oxygen uptake efficiency slope (OUES) may be of value. In the present observational study we evaluated the exercise capacity with maximal and submaximal parameters in a group of Fontan patients with an extracardiac conduit and determined their prognostic value. Sixty Fontan patients followed up in the Leiden University Medical Center who have performed an exercise test were included in this retrospective study. Exercise tests were performed at a median age of 11 years. Fontan patients showed on average lower values for all exercise parameters compared to reference values
