January 2022
Objective: To demonstrate the non-inferiority of Clinical Pregnancy Rates from Progestin-Primed Ovarian Stimulation compared to the GnRH Antagonist Protocol when the freeze-all and blastocyst transfer strategy is applied.
Methods: A retrospective study included all IVF cycles performed at Pró-Criar Reproductive Medicine Center, Belo Horizonte, Minas Gerais, Brazil, between May 2018 and May 2019 using a GnRH antagonist analogue or oral progestins to block the LH peak in IVF/intra-cytoplasmic sperm injection (ICSI) cycles for infertility treatment.
Results: The primary outcome of our study was Clinical Pregnancy Rate at the first ET (Blastocyst), which were 58.
Primary ovarian insufficiency is a cause of infertility that affects about 1% of women under 40 years old, and is considered as idiopathic in 75% of cases. This review aims to carry out a critical synthesis of the knowledge of the chemical agents likely to affect follicular stock in humans and / or animals, by direct toxicity to follicles, or by increasing their recruitments. For the majority of toxic agents, only experimental data are currently available.

July 2020
Objective: To identify the main research interests of Brazilian patients in the field of infertility and assisted reproductive technology (ART) treatments.
Methods: This prospective multicenter cross-sectional study was carried out in Brazil. Patients attending five fertility centers from the Huntington Group between October and December 2018 were invited to join the study, which consisted of answering an anonymous survey online.
Research Question: What are the main research interests among patients of assisted reproductive technologies (ART)?
Design: Cross-sectional study consisting of an anonymous online survey sent to 2112 patients from eight centres in four countries in 2018. Patients were asked to identify research questions relevant to them in the field of infertility and ART. Answers were categorized into topics and ranked by frequency.
Oocyte cryopreservation for future fertility: comparison of ovarian response between cancer and non-cancer patients.
JBRA Assist Reprod
April 2019
Objective: This study aimed to assess whether a diagnosis of cancer interferes with ovarian function prior to the treatment of the disease.
Methods: This observational retrospective study used data from medical records of ovarian stimulation cycles performed for purposes of oocyte cryopreservation.
Results: The included patients had a mean age of 35.
The present study aimed to evaluate the impact of vitrification on the viability of follicles using a three-dimensional (3D) in vitro culture. Bovine ovarian tissue samples ( = 5) obtained from slaughterhouses were utilized. The cortex was cut into small fragments of 2 × 3 × 0.

- The study evaluated the viability of bovine ovarian tissue after cryopreservation using two methods: slow freezing and vitrification, comparing these to a control group.
- A total of 240 ovarian cortex fragments were analyzed, and no significant differences in follicular health were found between the slow freezing and vitrification methods, indicating both are viable for preserving ovarian tissue.
- The results suggest that vitrification might be a more efficient and cost-effective alternative for patients at risk of ovarian failure during treatment, while still maintaining viable follicles.
