In vitro maturation (IVM) of immature oocytes retrieved from surgically resected ovaries has been proposed as a method of fertility preservation in ovarian cancer patients undergoing definitive surgery. While there had been several reports of successful derivation of mature oocytes and or embryos, there have been no reports as yet of successful pregnancies. In this case report, we present a pregnancy and live birth from a young patient, with stage IIIC ovarian cancer, who had undergone fertility sparing surgery. The immature oocytes recovered after oophorectomy were fertilized after IVM. The embryos obtained were cryopreserved and later transferred to achieve a singleton healthy pregnancy leading to a live birth.

Oxidative stress (OS) is established as a key factor in the etiology of both male and female infertility, arising from an imbalance between reactive oxygen species (ROS) production and the endogenous antioxidant (AOX) defenses. In men, OS adversely affects sperm function by inducing DNA damage, reducing motility, significantly impairing sperm vitality through plasma membrane peroxidation and loss of membrane integrity, and ultimately compromising overall sperm quality. In women, OS is implicated in various reproductive disorders, including polycystic ovary syndrome, endometriosis, and premature ovarian failure, leading to diminished oocyte quality, disrupted folliculogenesis, and poorer reproductive outcomes.

Importance: Patients with uterine factor infertility (UFI) have few options for family building. Uterus transplant is a feasible treatment for some patients; however, cost remains a significant concern.
Objective: To compare the cost effectiveness of treatment for patients with absolute uterine factor infertility to achieve 1-2 singleton births by gestational carrier or uterus transplant DESIGN: Decision analysis from the United States healthcare sector perspective, with time horizons to achieve one or two singleton births.
Objective: To compare pregnancy outcomes and serum progesterone levels between women who took sublingual (SL) progesterone lozenges versus intramuscular (IM) progesterone-in-oil for endometrial preparation and luteal support in programmed frozen embryo transfer (pFET) cycles.
Design: Retrospective cohort study.
Subjects: All patients who underwent pFET of a single euploid good-quality blastocyst between January 2018 and April 2023 at a single fertility center.

Objective: To compare the cost-effectiveness of a gestational carrier to a uterine transplantation in the treatment of absolute uterine-factor infertility.
Design: We performed a cost-effectiveness analysis using a decision-tree mathematical model comparing a gestational carrier to a uterine transplantation.
Subjects: Published literature was used to derive costs for solid organ transplant, immunosuppression, gestational carrier obtainment, in vitro fertilization, preimplantation genetic testing, and frozen embryo transfer.

Importance: Congenital Zika syndrome (CZS) can lead to a range of developmental and neurological issues, which increases the risk of early death. However, the all-cause and cause-specific mortality in children with CZS in the first 5 years of life remain unknown.
Objective: To compare the hazard of all-cause and cause-specific mortality before age 5 years among children with and without CZS in Brazil.
