PURPOSE: Prior studies suggest that pregnancy outcomes after autologous oocyte cryopreservation are similar to fresh in vitro fertilization (IVF) cycles. It is unknown whether there are differences in pregnancy and perinatal outcomes between cryopreserved oocytes and cryopreserved embryos. METHODS: This is a retrospective cohort study comparing pregnancy and perinatal outcomes between oocyte and embryo cryopreservation at a university-based fertility center. We included 42 patients and 68 embryo transfers in patients who underwent embryo transfer after elective oocyte preservation (frozen oocyte-derived embryo transfer (FOET)) from 2005 to 2015...

BACKGROUND: Children, adolescents, and young adults (children/youth) with differences/disorders of sex development (DSD) face challenges related to future fertility; this may be due to variations in gonadal development, and, for some, gonadectomy performed to reduce the risk of malignancy. Childhood may be the only time for preservation of biological fertility potential for children/youth who undergo gonadectomy or have early gonadal failure. Fertility-related decision-making for these patients is particularly complicated, due to the need for parental proxy decision-making, potential discordance between gender identity and gonadal type, and uncertain future assisted reproductive technologies...

More than 60,000 young adults are diagnosed with cancer each year in the United States. Many will not have started or completed their families at the time of diagnosis, and reproductive concerns are common. Practice guidelines from a number of professional organizations, including the American Society of Clinical Oncology, highlight the need for oncology clinicians to address fertility with their at-risk patients by discussing options for fertility preservation. Fertility preservation options for men include sperm banking (through manual stimulation, electroejaculation, and testicular sperm extraction) and testicular shielding...

Chronic kidney disease (CKD) affects hypothalamic-pituitary-gonadal axis function, leading to menstrual abnormalities, sexual dysfunction, functional menopause, and loss of fertility. Pregnancy in a patient with CKD is associated with a higher risk of complications to both the mother and the fetus, highlighting the importance of contraceptive counseling at all stages of CKD. There has been limited research on the safety and efficacy of different contraceptive methods in the CKD population, and it is important to tailor the choice of contraception to the patient's lifestyle and comorbidity status...

Carney complex is a rare genetic disease characterised by a complex of myxomas, spotty pigmentation and endocrine overactivity. At diagnosis, about one-third of male patients presents with testicular tumours, namely large cell calcifying Sertoli cell tumours, which are often multicentric and/or bilateral and have a low malignant potential. Although radical orchiectomy is the gold standard for the treatment of testicular neoplasms, a conservative approach with partial orchiectomy or tumourectomy may be the best treatment option for these patients, allowing the preservation of endocrine function, fertility and body image...

BACKGROUND: Chemotherapy for breast cancer may have a negative impact on reproductive function due to gonadotoxicity. Fertility preservation via banking of oocytes or embryos after ovarian stimulation with FSH can increase the likelihood of a future live birth. It has been hypothesized that elevated serum estrogen levels during ovarian stimulation may induce breast tumour growth. This has led to the use of alternative stimulation protocols with addition of tamoxifen or letrozole. The effectiveness of these stimulation protocols in terms of oocyte yield is unknown...

The performance and removal mechanisms of a hybrid constructed wetland (HCW) followed by a willow planted filter (WPF) were evaluated for the treatment of a leachate contaminated by wood pole preservatives (pentachlorophenol (PCP) and chromated copper arsenate) to reach the storm sewer discharge limits. The HCW aimed to dechlorinate the PCP and polychlorodibenzo-p-dioxins/polychlorodibenzofuran (PCDD/F) and to remove metals by adsorption and precipitation. The HCW was efficient in removing PCP (>98.6%), oil, arsenic (99...

Long term storage of canine frozen semen is conventionally performed in liquid nitrogen (LN2). However, previous works in freezing canine semen using a -80 °C ultra-freezer (-80°C-UF) showed no differences on sperm quality after thawing. The main objective of this study was to compare the effects of the freezing techniques using LN2 or -80°C-UF on sperm function and in vivo fertility of frozen-thawed dog semen. The sperm-rich fraction of the ejaculate was collected separately from five Chihuahua breed, and each one divided into two aliquots, and frozen and stored in LN2 or -80°C-UF...

INTRODUCTION: In the last decades, long-term outcomes of young women with breast cancer have greatly improved, raising several new survivorship needs which include fertility preservation and pregnancy. The prejudice against pregnancy after breast cancer is still alive among different healthcare providers (e.g. gynecologists, oncologists, general practitioners) and women are often confused and left alone in their family decision planning. EVIDENCE ACQUISITION AND SYNTHESIS: All the available retrospective data confirm pregnancy after breast cancer is safe both for the mother and the offspring, also in women with hormone receptor positive disease...

Engineered nanomaterials are directly applied to the agricultural soils as a part of pesticide/fertilize formulations or sludge/manure amendments. No prior reports are available to understand the surface interactions between gold nanoparticles (nAu) and soil components, including the charcoal black carbon (biochar). Retention of citrate-capped nAu on 300-700 °C pecan shell biochars occurred rapidly and irreversibly even at neutral pH where retention was less favorable. Uniform organic (primarily citrate ligands) layer on nAu was observable by TEM, and was preserved after the retention by biochar, which resulted in the aggregation or alignment along the edges of multisheets composing biochar...

A review is made of the current state of agriculture, emphasising issues of soil erosion and dependence on fossil fuels, in regard to achieving food security for a relentlessly enlarging global population. Soil has been described as "the fragile, living skin of the Earth", and yet both its aliveness and fragility have all too often been ignored in the expansion of agriculture across the face of the globe. Since it is a pivotal component in a global nexus of soil-water-air-energy, how we treat the soil can impact massively on climate change - with either beneficial or detrimental consequences, depending on whether the soil is preserved or degraded...

Neuroblastoma (NB) is the most common type of extracranial solid tumor in children with a high prevalence in toddlers. For childhood cancer survivors, preservation of reproductive potential is an important factor for quality of life. The optimization of NB minimal residual disease (MRD) detection in testicular tissue is crucial to evaluate the risk of malignant cell reintroduction. The first step in the present study was to assess the accuracy of reverse transcription-quantitative polymerase chain reaction (RT-qPCR) to detect tyrosine hydroxylase (TH), paired-like homeobox 2b (PHOX2B) and doublecortin (DCX) mRNA expression in frozen/thawed testicular tissues of patients with non-obstructive azoospermia (NOA) contaminated (in vitro model) with an increasing number of IMR-32 and SK-N-SH NB cells...

Organic nutrient sources such as farmyard manure, sewage sludge, their biogas digestates or other animal by-products can be valuable fertilizers delivering organic matter to the soil. Currently, especially phosphorus (P) is in the focus of research since it is an essential plant nutrient with finite resources, estimated to last only for some more decades. Efficient utilization of organic P sources in agriculture will help to preserve P resources and thereby has the potential to close nutrient cycles and prevent unwanted P-losses to the environment, one of the major causes for eutrophication of water bodies...

AIM: Primary ovarian non-Hodgkin's lymphoma is a very rare disease. Median age at diagnosis is estimated at 42 years, something that leads to fertility preservation issues in many cases. This was a case report study, presenting a rare case of bilateral primary ovarian non-Hodgkin's lymphoma. CASE REPORT: A 38-year old nulliparous woman, underwent exploratory laparotomy because of bilateral ovarian masses. Left salpingooophorectomy, partial omentectomy and excision of an ovarian mass of the right ovary was performed...

BACKGROUND: Despite a large body of data suggesting that delivery of fertility care to cancer patients is inconsistent and frequently insufficient, there is a paucity of literature examining training in fertility preservation for those physicians expected to discuss options or execute therapy. The study objective was to compare fertility preservation training between Reproductive Endocrinology & Infertility (REI) and Gynecologic Oncology (GYN ONC) fellows and assess the need for additional education in this field...

Multinational data on assisted reproduction techniques (IVF and intractytoplasmic sperm injection [ICSI], frozen embryo transfer, oocyte donation, preimplantation genetic diagnosis and fertility preservation) were collected from 159 institutions in 15 Latin American countries. A total of 41.34% of IVF-ICSI cycles were conducted in women aged 35-39 years and 23.35% in women aged 40 years and older. After removing freeze-all cases, delivery rate per oocyte retrieval was 25.05% for ICSI and 27.41% for IVF. Multiple births included 20...
