Over the past 30 years, advances in antineoplastic treatment led to a significant increase in the survival of patients with childhood cancer. In Europe and the United States, 82% of children, adolescents, and young adults survive 5 years from the cancer diagnosis and the majority achieves long-term survival into adulthood. The impact of cancer therapy on fertility is related to the age of the patient and to the duration, dose/intensity, and type of treatment. Exposure to chemotherapy or to radiation to gonads or pituitary brings long-term complications of cancer-directed therapies that include effects on reproductive capacity...

The use of supplements, such as porcine follicular fluid (pFF), fetal bovine serum and human serum albumin are widely used during in vitro maturation (IVM) in different species but these supplements contain undefined components that cause technical difficulties in standardization and influence the efficiency of IVM. Knockout serum replacement (KSR) is a synthetic protein source, without any undefined growth factors or differentiation-promoting factors. Therefore, it is feasible to use KSR as a defined component for avoiding effects of unknown molecules in an IVM system...

This is perhaps the most apt mantra of IVF (in vitro fertilisation) as a treatment in Australasia in this day and age. It is also important to note the truth in the identification of IVF being low skill-based, largely independent of the practitioner, but more importantly costly, and with few exceptions, only available in the private sector. Such revelations really require a rethink of the entire reproductive endocrinology and infertility (CREI) subspecialty. In fact, if there is only one solution to all fertility problems - that of the 'effective IVF procedure' - why not do away completely with the clinician and simply have nurse practitioners who oversee the identified issue of an individual or couple wanting a pregnancy? This in conjunction with the outstanding scientific advances that led to the initiation and promulgation of IVF really would reduce costs by cutting out the unnecessary clinician middle-person who is unimportant in the equation...

Background: Women undergoing in vitro fertilization (IVF) cycles should successfully go through multiple points during the procedure (i.e., implantation, clinical pregnancy, no spontaneous abortion and delivery) to achieve live births. In this study, data from multiple cycles and multiple points during the IVF cycle are collected for each individual to model the effects of factors associated with success at different stages of IVF cycles in Iranian infertile women. MATERIALS AND METHODS: This historical cohort study includes 996 assisted reproductive technology (ART) cycles of 511 infertile women...

In fish, many factors can affect reproduction during in vitro fertilization, therefore determination of the factors that affect affecting gamete quality is needed. However, few studies have focused on gamete quality and the ploidy status. This study was conducted to elucidate whether oocyte storage can affect ploidy status, survival, and embryo viability in the characid species Astyanax altiparanae. Oocytes were stored in Dulbecco's phosphate-buffered saline (PBS) at 26°C, then aliquots were fertilized immediately after extrusion (control) and also after 60, 120, 180, and 240 min of storage...

PURPOSE: Partial thawing of a vial of cryopreserved sperm (shaving) is sometimes applied as a measure to preserve sperm for further use, particularly in cases of very restricted sperm quantity. However, mechanical violence may disrupt the sperm-wall and lead to impaired in-vitro fertilization (IVF) outcomes. MATERIAL AND METHODS: In a retrospective case-control study at a tertiary, university-affiliated medical center, we compared the IVF/intracytoplasmic sperm injection (ICSI) outcomes of patients who used donor sperm following partial thawing (shaving) of the vial of cryopreserved sperm (n = 99) to a control group consisting of patients for whom the vial of sperm was completely thawed before use (n = 99)...

BACKGROUND: Changing sociodemographic patterns with an increase in the age of childbirth have affected fertility rates worldwide. With advancing reproductive medicine, assisted reproductive techniques (ARTs) are becoming common. While dermatological manifestations in normal pregnancies have been well documented, there is a paucity of data regarding cutaneous manifestations in patients undergoing ART. OBJECTIVES: The objectives of our study were to estimate the incidence and types of dermatological manifestations in patients undergoing in vitro fertilisation (IVF) and to study their associations with age, type of infertility, and outcome of the procedure...

PURPOSE: The purpose of this study was to determine the heterotopic pregnancy rate using fresh versus frozen-thawed embryo transfers and factors associated with heterotopic pregnancy (HP). Management and clinical outcomes after heterotopic pregnancy were also evaluated. METHODS: In this retrospective cohort study, we included 12,484 women who had clinical pregnancies after in vitro fertilization treatment at our fertility center between 2012 and 2017. Patients received fresh day 3 embryos (F-D3 group), fresh day 5 blastocysts (F-D5 group), frozen-thawed day 3 embryos (T-D3 group), or frozen-thawed day 5 or 6 blastocysts (T-D5/6 groups) transfers...

BACKGROUND: Among women who are undergoing in vitro fertilization (IVF), the transfer of frozen embryos has been shown to result in a higher rate of live birth than the transfer of fresh embryos in those with infertility associated with the polycystic ovary syndrome. It is not known whether frozen-embryo transfer results in similar benefit in women with infertility that is not associated with the polycystic ovary syndrome. METHODS: We randomly assigned 782 infertile women without the polycystic ovary syndrome who were undergoing a first or second IVF cycle to receive either a frozen embryo or a fresh embryo on day 3...

BACKGROUND: Elective frozen-embryo transfer has been shown to result in a higher live-birth rate than fresh-embryo transfer among anovulatory women with the polycystic ovary syndrome. It is uncertain whether frozen-embryo transfer increases live-birth rates among ovulatory women with infertility. METHODS: In this multicenter, randomized trial, we randomly assigned 2157 women who were undergoing their first in vitro fertilization cycle to undergo either fresh-embryo transfer or embryo cryopreservation followed by frozen-embryo transfer...

BACKGROUND: No research exists on American Indian pregnancy rates following infertility treatment. Most racial/ethnic fertility research has focused on pregnancy following in vitro fertilization, with only rare studies looking at intrauterine insemination (IUI). The objective of our study was to compare fecundability following IUI by race/ethnicity, with a special focus on American Indians. METHODS: This was a retrospective analysis of subjects undergoing IUI July 2007-May 2012 at a university-based infertility clinic...
