RESUMEN

New family configurations are emerging concurrently with improved assisted reproduction techniques, including the use of donated gametes. Most indications for treatment when using donated eggs are caused by an age-related decrease in reproductive capacity. We evaluated the emotional state regarding accepting egg donation in participants who chose this option for in vitro fertilization cycles. This is a retrospective, Brazilian cohort study, based on data collected from sixty psychological counseling sessions with participants that opted to be enrolled in an egg donation program. A single professional conducted semi-structured psychological counselling sessions. The data were analyzed using a thematic analysis as the qualitative methodology. Two years after the psychological counseling sessions, participants were contacted to obtain information about their outcomes. Of 60 sessions, 19 (32%) were classified as involving participants with positive emotional state (group 1), 14 (23%) with unfavorable emotional state (group 2), and 27 (45%) without evident classification (group 3). Three couples did not undergo treatment until two years after the psychological counselling session and the other couples underwent treatment in a period ranging from 1-8 months after the session. This is the first study in the Brazilian population regarding the acceptance of egg donation. The process of acceptance of infertility and the impossibility to have a biological child is fundamental to gradually accepting a new way of becoming a parent. Psychological counseling can contribute to reflecting on the use of donated eggs, exploring its emotional implications and identifying the need for psychotherapeutic work to address conflict and suffering.

RESUMEN

A 26-year-old patient was admitted in our center with one year of infertility history after a miscarriage. She was diagnosed with uterus bicornis unicollis and deep infiltrating endometriosis (DIE); therefore, she underwent endometriosis focus removal surgery. After six-months, she conceived spontaneously and delivered one healthy baby. One year after the first pregnancy delivery, she conceived spontaneously and delivered twins in an extremely rare condition of uterus bicornis unicollis, of which there are only 15 cases reported worldwide. Both pregnancies were monitored every two or three weeks using ultrasonography to assess fetal growth, and cervical length was measured to assess the risk of premature delivery.

RESUMEN

OBJECTIVE: Given that the embryo culture medium secretome reflects the embryo development, we hypothesize that protein profiles are affected according to infertility factors, which can be responsible for detrimental embryonic developmental competence. The aim of this study was to screen the protein profile of conditioned embryo culture media in patients presenting deep infiltrating endometriosis (ENDO) and polycystic ovarian syndrome (PCOS) undergoing IVF, by proteomics approaches. The control group was constituted by tubal factor patients. METHODS: Patients underwent in vitro fertilization (IVF) treatment as routine and oocytes were fertilized by ICSI. The embryos were group cultured until day 3 of development, and after transfer the culture media were collected. For the proteomics analysis, two pools of samples were prepared for groups CONTROL and PCOS, and 4 pools of samples for group DIE. Samples were prepared to deplete high abundant proteins and followed evaluated by high throughput proteomics approach. RESULTS: The embryonic organ and tissue development were physiological functions activated, based on proteins identified in the 3 study groups of samples. The samples coming from DIE patients presented a high calcium activity and on the other hand, embryos coming from PCOS patients showed a decreased calcium action. Other pathways as grow factors through the EGF signaling pathway overexpressed in ENDO culture medium and protein kinase A in PCOS were also observed. CONCLUSIONS: Proteomic embryonic secretome will advance our knowledge of early embryogenesis and additionally could lead to improved selection of embryos for transfer warrants further investigation.

RESUMEN

OBJECTIVE: To select embryos with higher implantation potential, the extended culture has been the most frequently applied strategy worldwide, and consequently leads to higher live birth rates per transfer. Sperm quality is a determining feature, and it may influence the outcomes of IVF from fertilization to embryo development. Therefore, we hypothesize that blastocyst formation may also be impaired by general semen quality. METHODS: We analyzed 4205 IVF cycles. Four study groups were designed according to semen quality: normal, mild alteration, severe alteration and epididymis. All cycles were intended to extend embryo culture until the blastocyst stage, and embryo development was evaluated. RESULTS: Regarding cleavage rate, the normal and mild alteration semen groups were equivalent, and the severe alteration and epididymis semen groups were equivalent to each other. The blastocyst formation rate decreased with semen quality. At least one blastocyst formed in 79.9% of cycles for the normal semen group, whereas the percentage of cycles with the formation of at least one blastocyst was slightly lower for the mild alteration (75.6%), severe alteration (76.4%) and epididymis (76.8%) semen groups. A multivariate logistic regression showed that for each additional cleaved embryo on day 3, the chance of having at least one blastocyst doubles. Additionally, the chance of having at least one blastocyst decreased when semen presented mild or severe alterations. CONCLUSION: The general quality of sperm is a good predictor of blastocyst formation, significantly affecting the likelihood of having at least one blastocyst at the end of the cycle. Based on our findings, it is necessary to consider general semen quality and the number of cleaved embryos when forecasting the possibility of blastocyst formation and transfer in an extended culture system.

RESUMEN

OBJECTIVE: The aim of this study was to assess the knowledge about the risk of infertility in cancer patients after treatment, and the options for fertility preservation based on a survey carried out during the 2013 Pink October campaign. METHODS: This survey was carried out during the 2013 Pink October event in the most important public park of São Paulo, Brazil. Approximately 900 people expressed interest in learning about breast cancer prevention and fertility preservation by participating in workshops, and 242 people filled out a questionnaire. RESULTS: Most of the respondents (78.5%) were women, and one-fourth (25%) had at least one relative with gynecological cancer. Among women over 40 years of age, 86.3% had been screened for breast cancer at some point. However, few participants (34.0%) were aware that cancer treatment can lead to infertility or had heard about fertility preservation options (22.0%). Having a relative with cancer did not influence their knowledge about fertility preservation (22.4% versus 21.3%; p=0.864). However, a higher educational level was significantly associated with more knowledge about the effects of cancer on fertility and options for fertility preservation. CONCLUSIONS: The majority of participants did not have knowledge about the impact of oncologic treatment on fertility and did not know that there are options to preserve fertility in cancer patients. Awareness of infertility risk factors is an essential first step to safeguard future fertility, and therefore, more educational initiatives are needed to spread knowledge about oncofertility.
