Abstract
Abstract
Study question
Is the composition of AMH isoforms different in follicular fluids (FF) and granulosa cells (GCs) from human small antral follicles?
Summary answer
There is a high viability of AMH isoforms in FFs and GCs. Even between same size follicles from the same women, the isoform composition differs.
What is known already
Anti Müllerian Hormone (AMH) is a member of the TGF-β superfamily produced by follicular granulosa cells (GCs) in women from late gestation to the end of reproductive live. AMH is suggested to inhibit aromatase (i.e. CYP19) expression and thereby decreasing the conversion of androgens to oestrogens in humans, especially in small antral follicles before dominance is achieved and thereby act as a gatekeeper of ovarian steroidogenesis. However, the exact function and processing of AMH in human follicles is still not clarified.
Study design, size, duration
This retrospective study measured AMH isoforms in human FF and GCs from small antral follicles using ELISA, Western blot, and immunofluorescence analysis. A total of 41 female adolescents and women aged 15 to 38 years (mean age: 29.7 years), who underwent ovarian tissue cryopreservation (OTC) at the University Hospital of Copenhagen, Rigshospitalet were included between year 2006 and 2020 included.
Participants/materials, setting, methods
Donated human ovarian medulla tissue were FFs and GCs were obtained in connection with OTC. The following isoforms were evaluated in FFs using ELISA analysis: full-length AMH precursor (proAMH), cleaved associated AMH (AMHN,C), N-terminal pro-region (AMHN), and active C-terminal (AMHC) AMH. Antibodies specific for the N-terminal and the C-terminal AMH were used in both Western blot and immunofluorescence analysis of FFs and GCs.
Main results and the role of chance
A negative correlation between follicle diameter and the mentioned AMH forms were detected. Moreover, Western blot analysis detected various AMH forms in both FFs and GCs, which did not match the above-mentioned consensus forms suggesting an unknown proteolytic processing of AMH. The presence of these new molecular weight isoforms of AMH differs between individual follicles of identical size from the same woman.
Limitations, reasons for caution
The study group is limited and the significance of the variable AMH isoforms compositions between follicles cannot not be clarified from this data.
Wider implications of the findings
Collectively, these data suggest that intrafollicular processing of AMH is complex and variable, and thus, it may be difficult to develop an antibody based AMH assay that detect all AMH isoforms. Furthermore, the variability between follicles suggests that designing a proper standard will be difficult.

Abstract
The luteinizing hormone receptor (LHCGR) has a little studied polymorphic 6 bp insertion (rs4539842/insLQ). This study has evaluated the insLQ polymorphism in relation to potential associations with hormonal characteristics of human small antral follicles (hSAFs). In total, 310 hSAFs were collected from 86 women undergoing fertility preservation. Analysis included hormonal profile of 297 follicular fluid (FF) samples and 148 corresponding granulosa cells samples were evaluated by qPCR for selected genes. Significantly reduced and non-detectable mRNA levels of anti-Müllerian hormone receptor II (AMHR2) and LHCGR, respectively, were observed for insLQ/insLQ compared to -/insLQ and the -/- genotypes. Moreover, LHCGR and CYP19a1 together with oestradiol and inhibin-B were significantly increased in -/insLQ compared to the -/- genotype. The homozygous insLQ genotype showed strong significant associations to GC specific genes LHCGR and CYP19a1, which may translate into significant changes in FF hormone profiles and an altered LH signaling.

Abstract
Recombinant FSH proteins are important therapeutic agents for the treatment of infertility, including follitropin alfa expressed in Chinese Hamster Ovary (CHO) cells and, more recently, follitropin delta expressed in the human cell line PER.C6. These recombinant FSH proteins have distinct glycosylation, and have distinct pharmacokinetic and pharmacodynamic profiles in women. Comparative experiments demonstrated that follitropin delta and follitropin alfa displayed the same in vitro potency at the human FSH receptor, but varied in their pharmacokinetics in mouse and rat. While follitropin delta clearance from serum depended in part on the hepatic asialoglycoprotein receptor (ASGPR), follitropin alfa clearance was unaffected by ASGPR inhibition in rat or genetic ablation in mice. The distinct properties of follitropin delta and follitropin alfa are likely to contribute to the differing pharmacokinetic and pharmacodynamic profiles observed in women and to influence their efficacy in therapeutic protocols for the treatment of infertility.

Abstract
Regulation of human ovarian steroidogenesis differs from other species and precise knowledge on how human small antral follicles (hSAF) develop and acquire competence for continued growth and steroid output is still incomplete. The present study has characterized almost 1,000 normal hSAF collected in connection with cryopreservation of ovarian tissue for fertility preservation. The antral follicles (ranging from 3 to 13 mm) were generally aspirated from one ovary surgically removed during the natural cycle, and the follicular fluid (FF) and the granulosa cells (GC) were isolated and snap-frozen. In FF, the following hormones were measured: inhibin-B, inhibin-A, AMH, follistatin, PAPP-A, estradiol, progesterone, testosterone, and androstenedione. In GC, mRNA gene expressions using q-PCR were measured for the following genes: FSHR, AMH, CYP19, and AR. All samples in which one of the abovementioned parameters was measured were included, but typically multiple parameters were measured. Highly significant differences in concentration and follicular content in relation to follicular diameter were found for all measured hormones despite massive variability in-between follicles for any given diameter. The results demonstrate that profound changes take place in the hormonal microenvironment around follicular diameters of 8-11 mm corresponding to when follicular selection occurs. At this point, inhibin-B and inhibin-A showed distinct peaks concomitant with a significant reduction in both AMH protein and mRNA expression. Concentrations of inhibins, androgens, FSHR, and AR were intimately associated, and it is suggested that inhibin-B in combination with PAPP-A and thereby IGF2 activity exerts important paracrine signaling at follicular selection. At the same time upregulation of estradiol synthesis and CYP19 mRNA expression increased steroid output profoundly. Furthermore, the highly significant association between FSHR and AR mRNA gene expression enforces important functions of androgens in follicular development. Collectively, these data reintroduce the understanding of the follicular phase as two parted in which regulation of steroidogenesis differs. The profound changes taking place around follicular selection highlight important paracrine actions of TGF-β family members and IGFs for securing dominance of the selected follicle.

Abstract
Granulosa cell (GC) expressed androgen receptors (AR) and intrafollicular androgens are central to fertility. The transactivating domain of the AR contains a polymorphic CAG repeat sequence, which is linked to the transcriptional activity of AR and may influence the GC function. This study aims to evaluate the effects of the AR CAG repeat length on the intrafollicular hormone profiles, and the gene expression profiles of GC from human small antral follicles. In total, 190 small antral follicles (3-11 mm in diameter) were collected from 58 women undergoing ovarian cryopreservation for fertility preservation. The biallelic mean of the CAG repeat lengths were calculated for each woman, and grouped in three groups: Long CAG repeats (23-26 mean CAG); medium CAG repeats (20.5-22.5 mean CAG) and short CAG repeats (17.5-20.0 mean CAG). The following parameters were measured: follicle diameter, intrafollicular levels of Anti-Müllerian Hormone (AMH), progesterone, oestradiol, testosterone and androstenedione, and GC gene expression levels of FSHR, LHR, AR, CYP19A1, and AMH. The long CAG repeat lengths were associated with significantly decreased testosterone levels, as compared to medium CAG repeats (P = 0.05) and short CAG repeats (P = 0.003). Furthermore, in follicles 3-6 mm in diameter, the long CAG repeats were associated with significantly increased LHR and CYP19A1 gene expression levels compared to short CAG repeat lengths (P = 0.004 and P = 0.04 respectively), and significantly increased LHR expression compared to medium CAG repeat lengths (P = 0.03). In conclusion, long CAG repeat lengths in the AR were associated to significant attenuated levels of androgens and an increased conversion of testosterone into oestradiol, in human small antral follicles.

Abstract
STUDY QUESTION What are the results of transplanting cryopreserved ovarian tissue? SUMMARY ANSWER The transplanted ovarian tissue can last up to 10 years, with no relapses following the 53 transplantations, and the chance of a successful pregnancy is currently around one in three for those with a pregnancy-wish. WHAT IS KNOWN ALREADY Cryopreservation of ovarian tissue is now gaining ground as a valid method for fertility preservation. More than 36 children worldwide have now been born following this procedure. STUDY DESIGN, SIZE, DURATION This is a retrospective cohort study of 41 women who had thawed ovarian tissue transplanted 53 times over a period of 10 years, including 1 patient who was lost to follow-up. PARTICIPANTS/MATERIALS, SETTING, METHODS The 41 Danish women, who had in total 53 transplantations, were followed for ovarian function and fertility outcome. Safety was assessed by monitoring relapse in cancer survivors. MAIN RESULTS, AND THE ROLE OF CHANCE Among 32 women with a pregnancy-wish, 10 (31%) had a child/children (14 children in total); this included 1 woman with a third trimester on-going pregnancy. In addition, two legal abortions and one second trimester miscarriage occurred. A total of 24 clinical pregnancies were established in the 32 women with a pregnancy-wish. The tissue remained functional for close to 10 years in some cases and lasted only a short period in others. Three relapses occurred but were unlikely to be due to the transplanted tissue. LIMITATIONS, REASONS FOR CAUTION Self-report through questionnaires with only in-one hospital formalised follow-up of transplanted patients could result in unreported miscarriages. The longevity of the tissue may vary by few months compared with those reported because some patients simply could not remember the date when the tissue became non-functional. WIDER IMPLICATIONS OF THE FINDINGS Cryopreservation of ovarian tissue is likely to become integrated into the treatment of young women, with cancer, who run a risk of losing their fertility. The full functional lifespan of grafts is still being evaluated, because many of the transplanted women have continued to maintain ovarian activity. Some of our first cases have had tissue functioning for ∼ 10 years.

Abstract
The concentration of the important second messenger cAMP is regulated by phosphodiesterases (PDEs) and hence an attractive drug target. However, limited human data are available about the PDEs in the ovary. The aim of the present study was to describe and characterise the PDEs in the human ovary. Results were obtained by analysis of mRNA microarray data from follicles and granulosa cells (GCs), combined RT-PCR and enzymatic activity analysis in GCs, immunohistochemical analysis of ovarian sections and by studying the effect of PDE inhibitors on progesterone production from cultured GCs. We found that PDE3, PDE4, PDE7 and PDE8 are the major families present while PDE11A was not detected. PDE8B was differentially expressed during folliculogenesis. In cultured GCs, inhibition of PDE7 and PDE8 increased basal progesterone secretion while PDE4 inhibition increased forskolin-stimulated progesterone secretion. In conclusion, we identified PDE3, PDE4, PDE7 and PDE8 as the major PDEs in the human ovary.

Abstract
OBJECTIVE Evaluating the developmental competence of immature oocytes collected from surplus medulla tissue in connection with ovarian tissue cryopreservation for fertility preservation. DESIGN Cohort comparative study. SETTING University laboratory in Denmark from 2011-2012. POPULATION 69 girls and women (0-38 years of age) who each had one ovary cryopreserved for fertility preservation. METHODS Ovaries were obtained directly from the local hospital or from collaborating hospitals (two to five hours' transport on ice). Immature oocytes were aspirated from large antral follicles visible on the ovaries, and collected from the saline solution, containing surplus medulla tissue, following dissection of the ovarian cortical tissue for cryopreservation. The immature oocytes were cultured for 48 h in an Embryoscope™ Time-lapse System or in culture dishes overlaid with liquid paraffin using commercial and in-house supplemented culture media. MAIN OUTCOME MEASURES Maturation rate for immature oocytes reaching metaphase II. RESULTS With a maturation rate of 3.1%, only 21 of 682 immature oocytes reached metaphase II. Immature oocytes from ovaries that had been transported on ice for two to five hours performed significantly poorer than those recovered immediately after surgery. Addition of epidermal growth factor and follicle fluid from human small antral follicles to the culture medium did not augment the maturation rate. Immature oocytes cultured in the Embryoscope performed significantly better than those in conventional culture dishes. CONCLUSIONS In vitro maturation of immature oocytes should only be attempted clinically from visible antral follicles and where the ovary is not subjected to a cooling period prior to recovery of immature oocytes.

The present study correlated concentrations of activin A and follistatin in follicular fluid (FF) from human small antral follicles to FF concentrations of AMH, inhibin B, progesterone, and oestradiol and to the mRNA expression of FSH-receptor (FSHR), LH-receptor (LHR), AMH-receptor2 (AMHR2), CYP19a, and androgen-receptor (AR) in the corresponding granulosa cells (GC). FF from 144 follicles (3-12 mm in diameter) was included whereas mRNA expression profiles were established in GC from 66 of the 144 follicles. Levels of follistatin remained constant in relation to follicular diameter, whereas activin A levels increased in follicles exceeding 10 mm in diameter. Levels of activin A and inhibin B showed a highly significant inverse association. Follistatin showed highly significant positive associations with AMH and inhibin B levels and with FSHR and AR gene expression in GC. This study revealed unexpected associations that probably reflect the complicated regulatory mechanisms governing human folliculogenesis.
