(Submitter supplied) The process of ovulation includes oocyte meiotic maturation, follicle rupture and transformation of the follicle into a corpus luteum. These events are initiated by the midcycle surge of gonadotropins and require the coordinated regulation of thousands of genes. The aim of the study was to monitor the changes in granulosa cell gene expression across five different time points during the first 36 hours of ovulation until follicle rupture, in order to increase our understanding of the events of human ovulation. more...

(Submitter supplied) Ovulatory dysfunction affects nearly 40% of women of reproductive age that are struggling with infertility. Ovulation is the culmination of a complex and long process during which most follicles undergo atresia instead of developing into preovulatory follicles. The rescue of follicles from atresia and their maturation towards ovulatory competence requires “a pas de deux” between endocrine and locally-produced factors. more...

(Submitter supplied) Study Question: What effects do maternal age and oocyte maturation stage have on the human oocyte transcriptome that may be associated with oocyte developmental potential? Summary Answer: Although polyadenylated transcript abundance changes during human oocyte maturation irrespective of age, young (YNG) and advanced maternal age (AMA) metaphase II (MII) oocytes exhibit divergent transcriptomes. What is known already: Maternal age and maturation stage affect oocyte polyadenylated transcript abundance in human oocytes. more...

(Submitter supplied) Abstract STUDY QUESTION What is the effect of the chemical in vitro activation (cIVA) protocol compared with fragmentation only (Frag, also known as mechanical IVA) on gene expression, follicle activation, and growth in human ovarian tissue in vitro? SUMMARY ANSWER Although histological assessment shows that cIVA significantly increases follicle survival and growth compared to Frag, both protocols stimulate extensive and nearly identical transcriptomic changes in cultured tissue compared to freshly collected ovarian tissue, including marked changes in energy metabolism and inflammatory responses. more...

(Submitter supplied) Objective: To study post-hatching development after transfer of morphologically good quality embryos that survived in vitro maturation under lipolytic conditions using a well-established and recognized bovine model. Design: prospective study with a crossover design. Setting: research laboratory. Animals: 8 healthy multiparous non-lactating Holstein cows used in repeated embryo transfers. Intervention(s): Bovine cumulus oocyte complexes (COCs) were in vitro matured in the presence of either 1) a combination of elevated pathophysiological concentration of palmitic acid (PA) and physiological concentrations of stearic acid (SA) and oleic acid (OA) (HIGH PA), or 2) physiological concentrations of PA, SA and OA (BASAL). more...

(Submitter supplied) Goal: To identify the genes associated with the decision of undifferentiated spermatogonia to commit to a pathway of differentiation. Methods: testis mRNA profiles of 10 juvenile wild-type rhesus monkeys (3 vehicle-treated; 6 gonadotropin treated) were generated by deep sequencing, in triplicate and quadruplicate, using Illumina NextSeq500. The sequence reads that passed filters were analyzed at the transcript isoform level with TopHat followed by Cufflinks. more...

(Submitter supplied) Oocyte maturation defects are one contributing factor in unexplained female infertility. Failure of some oocytes to undergo germinal vesicle breakdown or progress to second meiotic metaphase in response to an ovulatory stimulus can limit the number of high quality oocytes available for assisted reproduction. Understanding the molecular mechanisms that underlie oocyte maturation failure may lead to novel methods for increasing the number of high quality oocytes available for assisted reproduction, as well as providing new insight into the basic biology of oocyte maturation. more...

(Submitter supplied) Background: Early embryonic development is governed by maternal transcripts stored within the oocyte during oogenesis. Transcriptional activity of the oocyte ultimately dictates its developmental potential and may be influenced by maternal age, resulting in reduced competence of oocytes derived from women of advanced age, compared with the young. In the current study, RNA-Seq was used to perform transcriptome profiling of human GV and MII oocytes derived from young and advanced maternal age women. more...

(Submitter supplied) We examined the molecular profile of human endometrium on days 2, 3 and 4 of menstruation to identify genes and pathways that play a role in the menstrual process. Endometrial samples were collected by Pipelle biopsy on days 2 (n=9), 3 (n=9) or 4 (n=6) of menstruation and arrayed. We identified key gene pathways involved in menstruation and identified a number of genes not previously associated with the process (Paiva et al. more...

(Submitter supplied) The twenties are typically considered the prime reproductive years for women. However, in today’s modern world many women are choosing to delay family planning, resulting in an increase of females in their forties seeking fertility treatment. Although in vitro fertilization (IVF) with donated oocytes and preimplantation genetic testing may help to address the impact of maternal age, the success rate for IVF treatment in this age group is still significantly lower. more...

(Submitter supplied) The ovulatory LH surge induces rapid changes of transcriptome and cellular functions in granulosa cells (GCs) undergoing luteinization. However, it remains unclear how the changes in genome-wide gene expression are regulated. The changes of trimethylation of lysine 4 on histone H3 (H3K4me3) is associated with the rapid alteration of gene expression. In this study, we genome-widely investigated the changes of transcriptome and H3K4me3 status in mouse GCs undergoing luteinization during ovulation. more...

(Submitter supplied) Background: The gonadotropin-induced resumption of oocyte meiosis in preovulatory follicles is preceded by expression of epidermal growth factor (EGF)-like peptides, amphiregulin (AREG) and epiregulin (EREG), in mural granulosa and cumulus cells. Both the gonadotropins and the EGF-like peptides possess the capacity to stimulate resumption of oocyte meiosis in vitro via activation of a broad signaling network in cumulus cells. more...

(Submitter supplied) Although it is well established that the ovarian reserve diminishes with increasing age, and that a woman’s age is correlated to lower oocyte quality, the interplay of a diminished reserve and age on oocyte developmental competence is not clear. After maturation, oocytes are mostly transcriptionally quiescent, and developmental competence prior to embryonic genome activation (EGA) relies on maternal RNA and proteins. more...
