Vitrification method is widely used in oocyte cryopreservation for IVF but the birth rates are lower than that of the fresh oocyte. One of the known main reasons is structural instability of meiotic spindle and chromosome systems of mature oocyte. To get the best way for keeping competence of matured oocytes, we studied the best conditions for vitrification focused on equilibration times. The m...

The issue of fertility preservation in patients with cervical cancer is getting more and common considering the improved effectiveness early diagnosis treatment cancer. There a number evidence-based tactics available to diagnosed These have been proved effective include methods such as ovarian transposition; oocyte, embryo tissue cryopreservation. Nonetheless, there are no existing medical algo...

BACKGROUND Although cryopreservation of semen is a routine procedure for preserving male gametes, an efficient method of preserving fertility through oocyte freezing has only recently become available for women. In view of the limited female reproductive lifespan, oocyte freezing can now offer women some protection against the decline in fertility with aging. METHODS A survey was performed in...

To understand the application of artificial intelligence (AI), specifically Violet™ technology, in determining egg quality for women undergoing oocyte cryopreservation. Retrospective analysis at a fertility clinic. Patients 45yo and younger who underwent cryopreservation used Violet by Future Fertility from Mar 2020 to Apr 2021 were included. Cryopreservation statistics recorded. Oocyte outcome...

There are relatively few effective clinical options for preserving female fertility, particularly following aggressive chemotherapy and/or radiotherapy treatment protocols. This document reviews the scientific background, current technology, clinical results and potential future applications of two methods for preserving female fertility—ovarian tissue cryopreservation and oocyte cryopreservati...

oocyte, embryo and ovarian tissue cryopreservation are being increasingly proposed for fertility preservation among cancer patients undergoing therapy to enable them to have babies after the cancer is cured. embryo cryopreservation is not appropriate for single girls without any sperm partner and also because oocyte retrieval is an extended procedure, it is impossible in cases requiring immedia...

The technology so far applied clinically has been based directly on traditional human embryo cryopreservation protocols, and has produced relatively few offspring. Fortunately to date, no abnormalities have been reported from these pregnancies, regardless of the persistent concerns that freezing and thawing of mature oocytes may disrupt the meiotic spindle and thus increase the potential for an...

Cryopreservation of oocytes and embryos is commonly used to preserve fertility. However, women undergoing cancer treatment may not have the time or may not be good candidates for these options. Ovarian cortical tissue cryopreservation and subsequent tissue transplant has been proven successful yet inefficient in preserving larger secondary follicles, and is not recommended as a fertility preser...

With the increase in survivorship following cancer for women in their reproductive years, as well as an increase in survivorship with childhood cancers, there is a demand for perfecting current fertility preservation methods and generating new options for patients who are unable to pursue the conventional course of fertility treatments. Cryopreservation using a slow-cooling method for embryos i...

STUDY QUESTION What knowledge, attitudes and intentions do US obstetrics and gynecology (OB/GYN) residents have toward discussing age-related fertility decline and oocyte cryopreservation with their patients? SUMMARY ANSWER Most OB/GYN residents believe that age-related fertility decline, but not oocyte cryopreservation, should be discussed during well-woman annual exams; furthermore, nearly ...
