Abstract
BACKGROUND AND OBJECTIVES Previous studies reported that photobiomodulation (PBM) positively affects the mitochondrial respiratory chain in sperm, resulting in improved motility and velocity. As laser settings are not yet fully established, the present study aimed at optimizing PBM on human sperm. In addition, possible side-effects of PBM on sperm DNA fragmentation level and acrosomal integrity have been analyzed. STUDY DESIGN/MATERIALS AND METHODS A pulsed laser-probe (wavelength 655 nm, output power 25 mW/cm², impulse duration 200 nanoseconds) was used. Native fresh liquefied semen samples underwent radiation with energy doses of 0 (control), 4, 6, and 10 J/cm². Sperm parameters were assessed at 0, 30, 60, 90, and 120 minutes after radiation using a computer-assisted sperm analysis system. Motility and velocity of sperm from asthenozoospermic patients (n = 42) and normozoospermic controls (n = 22) were measured. The amount of DNA strand breaks was analyzed using ligation-mediated quantitative polymerase chain reaction in patients with asthenozoospermia (n = 18) and normozoospermia (n = 13). Post-irradiance acrosomal integrity was investigated using flow cytometry based on CD46 protein expression (n = 7). RESULTS Exposure to laser energy-doses of 4 and 6 J/cm² improved sperm motility and velocity in asthenozoospermic patients. PBM exhibited no significant effect on DNA fragmentation level and expression of CD46 serving as a biomarker for acrosome integrity. CONCLUSION PBM improves sperm motility parameters by maintaining DNA and acrosome integrity and, therefore, represents a promising new tool for assisted reproductive therapy. In particular, improving sperm motility in asthenozoospermic patients by PBM in future may contribute to increasing the chance for successful intrauterine insemination. The present trial has no clinical registration number, as only in vitro studies were performed. The study was approved by the local ethics committee and performed according to the Declaration of Helsinki. Lasers Surg. Med. © 2021 The Authors.

Abstract
RESEARCH QUESTION Is overnight transportation of ovarian tissue before cryopreservation in a centralized cryobank from the FertiPROTEKT network feasible? DESIGN Data from 1810 women with cryopreserved ovarian tissue after overnight transportation from December 2000 to December 2017 were analysed with a focus on transportation, tissue activity parameters and pregnancy, and delivery rates after transplantation. RESULTS A total of 92.4% of tissue samples arrived at ideal temperatures of 2-8°C, 0.4% were transported at temperatures lower than ideal and 6.4% were transported at temperatures that were too high, generally due to mishandling of the inlayed cool packs of the transportation boxes. In 62 women, 78 tissue transplantations were carried out. A subgroup of 30 women who underwent a single orthotopic transplantation with fulfilled criteria of a complete follow-up after transplantation until the end of study, a premature ovarian insufficiency after gonadotoxic therapy as well as the absence of pelvic radiation, was further analysed. In this group, transplantations into a peritoneal pocket accounted for 90%. Transplants were still active at 1 year and above after transplantation in 93.3%. Pregnancy and delivery rates were 46.7% and 43.3%, respectively, with one ongoing pregnancy at the end of the study. CONCLUSIONS Overnight transportation for central cryobanking is a feasible concept that results in high reproducible success rates through standardized professional tissue freezing and storage.

Abstract
The cryopreservation of ovarian tissue with subsequent transplantation of the tissue represents an established method of fertility protection for female patients who have to undergo gonadotoxic therapy. The procedure can be performed at any point in the cycle and thus generally does not lead to any delay in oncological therapy. With the aid of this procedure, more than 130 births to date worldwide have been able to be recorded. The birth rate is currently approximately 30% and it can be assumed that this will increase through the further optimisation of the cryopreservation and surgical technique. The concept paper presented here is intended to provide guidance for managing cryopreservation and transplantation of ovarian tissue to German-speaking reproductive medicine centres.

Abstract
OBJECTIVE To systematically review the reporting of MII (MII) oocyte development after xenotransplantation of human ovarian tissue. DESIGN Systematic review in accordance with the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA). SETTING Not applicable. PATIENT(S) Not applicable. INTERVENTION(S) Formation of MII oocytes after xenotransplantation of human ovarian tissue. MAIN OUTCOME MEASURE(S) Any outcome reported in Pubmed. RESULT(S) Six publications were identified that report on formation of MII oocytes after xenotransplantation of human ovarian tissue. CONCLUSION(S) Xenografting of human ovarian tissue has proved to be a useful model for examining ovarian function and follicle development in vivo. With human follicles that have matured through xenografting, the possibility of cancer transmission and relapse can also be eliminated, because cancer cells are not able to penetrate the zona pellucida. The reported studies have demonstrated that xenografted ovarian tissue from a range of species, including humans, can produce antral follicles that contain mature (MII) oocytes, and it has been shown that mice oocytes have the potential to give rise to live young. Although some ethical questions remain unresolved, xenotransplantation may be a promising method for restoring fertility. This review furthermore describes the value of xenotransplantation as a tool in reproductive biology and discusses the ethical and potential safety issues regarding ovarian tissue xenotransplantation as a means of recovering fertility.

Abstract
BACKGROUND Current strategies in cancer treatment have markedly increased the rates of remission and survival for cancer patients, but are often associated with subsequent sterility. While there are various options available to an adult female depending on the patient's particular situation, the only realistic option for preserving fertility in prepubertal females is to cryopreserve ovarian tissue. This is the first report of a morphologically mature oocyte collected from non-stimulated prepubertal ovarian tissue xenotransplants. METHODS Ovarian tissue from a 6 year old patient suffering from nephroblastoma was removed and cryopreserved for fertility preservation. The frozen-thawed ovarian tissue fragments were xenotransplanted to bilaterally oophorectomized severe combined immunodeficiency (SCID) mice to assess follicle development. RESULTS Antral follicle formation occurred post-xenotransplantation in a single ovarian fragment without exogenous hormone stimulation. A morphologically maturing oocyte was harvested from these follicles. CONCLUSIONS Prepubertal human ovarian follicles and oocytes can be matured after xenotransplantation even without exogenous hormone stimulation. These results indicate that tissue collected from prepubertal patients can support fertility in cancer survivors.

Abstract
BACKGROUND The problem of post-cancer infertility is of significant concern. The cryopreservation of ovarian tissue before cancer therapy with retransplantation after convalescence is the key to solving this problem. METHODS Cryopreservation of ovarian tissue was performed in 2005 after surgical operation, post-operative low-temperature 22 hour transportation, and freezing using a special, original design block constructed for the initiation of ice formation (ice-seeding). We present the construction and function of this block. RESULTS In 2011, it was noted that a baby was born after thawing and re-transplantation of ovarian tissue. The technical and biological aspects of initiated crystals formation in the process of cryopreservation are emphasised and discussed. CONCLUSIONS The first live birth in Germany after re-transplantation of cryopreserved ovarian tissue was noted. This cryopreservation was performed using the protocol described here. Block for auto-seeding of principally new construction recommended.

Abstract
OBJECTIVE To describe the first live birth after transplantation of ovarian tissue following overnight transportation of the tissue before freezing. DESIGN Technical note. SETTING University department of obstetrics and gynecology. PATIENT(S) A 25-year-old cancer survivor with previous Hodgkin disease and relapse. INTERVENTION(S) The ovarian tissue was kept cool for >20 hours in a special transport medium and a special cooling device before it was cryopreserved. After premature ovarian failure due to preconditioning chemotherapy for bone marrow transplantation, the cryopreserved ovarian tissue was transplanted orthotopically. MAIN OUTCOME MEASURE(S) Resumption of ovarian function after transplantation, recovery of fertility, and pregnancy. RESULT(S) Ovarian function returned in the patient 3 months after transplantation, as shown by follicle development and estrogen production. During the fifth menstrual cycle, mild stimulation with FSH was initiated in accordance with a low-dose protocol. When ultrasonography revealed a follicle 18-20 mm in size in the ovarian graft, hCG was added and the patient had sexual intercourse at the optimal time point. On day 14 of the luteal phase, hCG concentration and vaginal echography confirmed a viable intrauterine pregnancy, which resulted in a healthy live birth. CONCLUSION(S) Overnight transportation of ovarian tissue appears to be possible in combination with appropriate transportation logistics. However, further investigations are needed before this procedure can be offered as a chance for women to preserve fertility independently of direct access to a tissue-processing bank.

Abstract
BACKGROUND Several randomized controlled trials have not shown a benefit from preimplantation genetic screening (PGS) biopsy of cleavage-stage embryos and assessment of up to 10 chromosomes for aneuploidy. Therefore, a proof-of-principle study was planned to determine the reliability of alternative form of PGS, i.e. PGS by polar body (PB) biopsy, with whole genome amplification and microarray-based comparative genomic hybridization (array CGH) analysis. METHODS In two centres, all mature metaphase II oocytes from patients who consented to the study were fertilized by ICSI. The first and second PBs (PB1and PB2) were biopsied and analysed separately for chromosome copy number by array CGH. If either or both of the PBs were found to be aneuploid, the corresponding zygote was then also processed by array CGH for concordance analysis. RESULTS Both PBs were biopsied from a total of 226 zygotes from 42 cycles (average 5.5 per cycle; range 1-15) in 41 couples with an average maternal age of 40.0 years. Of these, the ploidy status of the zygote could be predicted in 195 (86%): 55 were euploid (28%) and 140 were aneuploid (72%). With only one exception, there was at least one predicted aneuploid zygote in each cycle and in 19 out of 42 cycles (45%), all zygotes were predicted to be aneuploid. Fresh embryos were transferred in the remaining 23 cycles (55%), and one frozen transfer was done. Eight patients had a clinical pregnancy of which seven were evolutive (ongoing pregnancy rates: 17% per cycle and 30% per transfer). The ploidy status of 156 zygotes was successfully analysed by array CGH: 38 (24%) were euploid and 118 (76%) were aneuploid. In 138 cases complete information was available on both PBs and the corresponding zygotes. In 130 (94%), the ploidy status of the zygote was concordant with the ploidy status of the PBs and in 8 (6%), the results were discordant. CONCLUSIONS This proof-of-principle study indicates that the ploidy of the zygote can be predicted with acceptable accuracy by array CGH analysis of both PBs.

Abstract
Previously, we reported on inter-individual and gender specific variations of LINE-1 methylation in healthy individuals. In this study, we investigated whether this variability could be influenced by age or sex hormones in humans. To this end, we studied LINE-1 methylation in vivo in blood-derived DNA from individuals aged 18 to 64 years and from young healthy females at various hormone levels during the menstrual cycle. Our results show that no significant association with age was observed. However, the previously reported increase of LINE-1 methylation in males was reconfirmed. In females, although no correlation between LINE-1 or Alu methylation and hormone levels was observed, a significant stable individual specific level of methylation was noted. In vitro results largely confirmed these findings, as neither estrogen nor dihydrotestosterone affected LINE-1 or Alu methylation in Hek293T, HUVEC, or MDA-kb2 cell lines. In contrast, a decrease in methylation was observed in estrogen-treated T47-Kbluc cell lines strongly expressing estrogen receptor. The very low expression of estrogen receptor in blood cells could explain the observed insensitivity of methylation at LINE-1 to natural hormonal variations in females. In conclusion, neither natural cycle of hormones nor age has a detectable effect on the LINE-1 methylation in peripheral blood cells, while gender remains an important factor.

Abstract
INTRODUCTION Polar body diagnosis (PBD) is a new diagnostic method for the indirect genetic analysis of oocytes, which is carried out as part of in vitro fertilization. The biopsy of polar bodies is technically demanding and cannot be adopted uncritically in routine practice, in the absence of robust data to support this laboratory procedure. METHODS Selective literature review and analysis of own PBD data. RESULTS The main application of PBD is the detection of chromosomal aneuploidies and maternally inherited translocations in oocytes. The major disadvantage of PBD is that the paternal contribution to the genetic constitution of the developing embryo cannot be evaluated. Moreover, the potential value of polar body biopsy for the diagnosis of monogenetic diseases is limited. DISCUSSION The role of PBD in improving of success rates in assisted reproduction requires evaluation in further clinical trials. For maternal translocations, PBD can be used to reduce the risk of miscarriage. Rapid development in the field of molecular diagnostic and biopsy techniques will also influence PBD and will most likely allow wider application of this method in the near future.

Abstract
OBJECTIVE To evaluate the viability of vitrified human germinal vesicle (GV)-oocytes to mature to metaphase II (MII) stage after "rapid" cooling directly in liquid nitrogen in comparison with "slow" cooling in a closed 0.5-mL straw (aseptic system), with or without dimethyl sulfoxide (DMSO) in vitrification solution. The possibility of avoiding parthenogenesis of the oocytes after vitrification using DMSO was investigated. DESIGN In vitro maturation after vitrification. SETTING Assisted reproduction centers. PATIENT(S) Patients undergoing standard superovulation treatment and having GV-oocytes after follicular puncture. INTERVENTION(S) The GV-oocytes were vitrified with long/short exposure to DMSO using slow or rapid cooling, then warmed and matured in vitro. MAIN OUTCOME MEASURE(S) Maturation after warming. RESULT(S) Oocyte development up to MII stage after vitrification with DMSO was 71% in the group with "rapid" cooling, and in groups with "slow" cooling, 68% and 72% for long and short exposure to DMSO, respectively. The maturation rate of GV-oocytes after slow cooling without DMSO was 51%. In the vitrification with long-term contact of oocytes with DMSO group, a high rate of parthenogenesis was observed. When vitrification with short-term contact of oocytes with DMSO at room temperature was used, no parthenogenesis was observed. CONCLUSION(S) Cryopreservation of human GV-oocytes in open-pulled straws OPS) using an aseptic slow cooling method gives high maturation rates but only in combination with DMSO. To avoid spontaneous parthenogenesis, the exposure to DMSO must occur for a reduced time and at room temperature.

Abstract
OBJECTIVE To document the possibility to double-cryopreserve human metaphase II and pronuclear oocytes. DESIGN Case report. SETTING University-based IVF center. PATIENT(S) A couple with primary andrological infertility. INTERVENTION(S) Pronuclear stage oocytes derived after sperm injection into frozen-thawed metaphase II oocytes were cryopreserved again for later transfer. MAIN OUTCOME MEASURE(S) Post-thaw survival rates and pregnancy. RESULT(S) Five metaphase II oocytes survived the freeze-thaw procedure. Three of five oocytes presented with two pronuclei after sperm injection and were cryopreserved again. Post-thawing, all three oocytes developed into good quality embryos for transfer. A singleton pregnancy was achieved, resulting in the birth of a healthy girl. CONCLUSION(S) Double-cryopreservation of oocytes at metaphase II and at pronuclear stage is a treatment option in human-assisted reproduction.

Abstract
Recent studies using polarized light microscopy revealed a correlation between the presence of a spindle in human metaphase II meiotic oocytes and the fertilization rate following intracytoplasmic sperm injection (ICSI). Using a new spindle imaging system, it was possible to visualize the spindle image and the conventional light microscopic view of the oocyte simultaneously. Using this system, time-lapse studies of the meiotic cycle of human oocytes were performed. The video sequences showed that during the transition from metaphase I to metaphase II, the spindle completely disappears for approximately 40-60 min. These data support the idea that at least in some oocytes, the absence of the spindle is more likely an indicator for physiological progression through an important developmental stage of meiosis rather than a cellular disturbance. In view of the low fertilization rates of oocytes with absence of spindles as reported in the literature, the underlying problem could simply be the incorrect timing of ICSI.

Abstract
It is widely accepted that it is possible to successfully cryopreserve human ovarian tissue by direct plunging into liquid nitrogen using permeable cryoprotectants only, without disaccharides. This study aimed to search for and test a new method for in-vitro culture of vitrified tissue. Ovarian biopsies were obtained during operative laparoscopy. Pieces of ovarian tissue were vitrified and warmed. After warming, tissue pieces were randomly distributed into three groups for further culture: in 2 ml of culture medium which was regularly renewed (group 1), in 30 ml of culture medium without agitation (group 2) and in 30 ml of culture medium with agitation (group 3). During the 2-week and 6-week culture, the growth of follicles within the vitrified-warmed ovarian tissue pieces was investigated. After 2 weeks of culture, mean numbers of non-degenerated follicles per mm(2) of tissue were 1.5, 1.7 and 4.5 for groups 1, 2 and 3 respectively (groups 1 and 2 versus group 3, P < 0.05). Agitation during culture of ovarian tissue is beneficial, and can be used as a prognostic tool for future warming and autotransplantation of ovarian tissue.

Abstract
OBJECTIVES To study the potential of embryo transfer after 3, 4 or 5 days of embryo culture under the German embryo protection law according to which only a maximum of three zygotes are allowed to be cultured for embryo transfer. STUDY DESIGN In a prospective study, 273 patients with assisted reproductive treatment were randomly allocated for transfer on days 3, 4 or 5. Pregnancy and implantation rates were evaluated in regard to day of transfer and results were compared by Chi-square or ANOVA test. RESULTS Out of 234 transfer cycles, 79 were performed on day 3, 76 on day 4 and 79 on day 5. Pregnancy and implantation rates were 41.8%/27.1% for transfer on day 3, 27.6%/14.1% for day 4 transfer and 16.5%/8.8% for transfer on day 5. These results were significantly different for pregnancy rates on day 3 versus day 5 (P < 0.001) and for implantation rates on day 3 versus day 4 (P < 0.005) and day 3 versus day 5 (P < 0.001). CONCLUSIONS These findings suggest that extended embryo culture is not beneficial when the option for embryo selection at later stages of development is not available.

OBJECTIVE To evaluate the viability of vitrified mouse pronuclear embryos after polar body biopsy by cooling directly in liquid nitrogen in comparison with cooling in closed 0.5 mL straw (aseptic system). DESIGN In vitro culture after vitrification. SETTING Department of Gynecological Endocrinology and Reproductive Medicine, University of Bonn, Germany. PATIENT(S) Superovulated mice. INTERVENTION(S) Biopsied embryos were vitrified, warmed, and cultured in vitro. MAIN OUTCOME MEASURE(S) Development after warming. RESULT(S) Development rates up to expanded blastocyst stage after in vitro culture were 25% in group with "direct" vitrification and 23% in group with "straw in straw" vitrification. CONCLUSION(S) Cryopreservation of biopsied mouse pronuclear embryos in open-pulled straws, which are placed inside a hermetically closed container, guarantees a complete isolation of embryos from liquid nitrogen and avoids potential contamination by pathogenic microorganisms. The combination of plunging this container into liquid nitrogen and rapid warming makes this process as efficient as conventional vitrification.

Abstract
Polar body biopsy and subsequent fluorescence in-situ hybridization (FISH) analysis allows detection of maternally derived chromosomal aneuploidies in human oocytes during IVF treatment. The development of a diode laser technique for the partial opening of the zona pellucida has stimulated the use of this technique to assist polar body biopsy. Laser-assisted polar body biopsy was performed in 140 IVF cycles from patients of advanced maternal age (> or =35 years). A total of 921 oocytes were treated by a laser for partial zona opening and polar body removal. FISH was performed for chromosomes 13, 16, 18, 21 and 22 and results were available for 903 oocytes (98%). In all, 443 oocytes (49.1%) were euploid and of these, 293 were fertilized. A total of 214 embryos were transferred in 120 embryo transfer cycles (1.78 per embryo transfer) resulting in 27 clinical pregnancies (22.5% per embryo transfer) with an implantation rate of 15.4%. Subsequently, five women aborted (18.5%) and 24 healthy children were born from the remaining 22 pregnancies, which gives a take home baby rate of 18.3% per transfer cycle. It is concluded that polar body biopsy using a diode laser system is as efficient as standard polar body biopsy using zona drilling.

Abstract
OBJECTIVES To simultaneously detect six chromosomes in a single round of fluorescence in situ hybridization (FISH) during polar body diagnosis and aneuploidy testing in human in vitro fertilization (IVF) treatment. METHODS A commercially available five-color FISH probe was modified by an additional chromosome probe. This kit was first tested on lymphocyte spreads and then used for polar body diagnosis (PBD) in patients with advanced maternal age and repeated implantation failure. The outcome of IVF treatment was compared with a control group. RESULTS All six chromosomes could be simultaneously detected and easily distinguished by FISH analysis. PBD and aneuploidy testing were performed in 75 treatment cycles and compared with 126 controls. The biochemical pregnancy rate was significantly higher in the PBD group (37.1% vs 22.9%, p < 0.05) and a trend was observed for higher clinical pregnancy and implantation rates (24.22% and 14.4% vs 18.62% and 10.8%, respectively) and lower abortion rates (20% vs 31.8%) following PBD. CONCLUSIONS The simultaneous detection of six chromosomes in a single FISH round is possible and can be applied to PBD. This approach may present another step towards increasing the number of chromosomes for aneuploidy testing.

Abstract
Human spermatozoa can be successfully cryopreserved without the use of cryoprotectants through vitrification at very high warming rates. This is achieved by plunging a small amount of frozen sperm suspension into a warming medium, or a large amount of sperm suspension into an agitated warming medium. The aim of the present study was to compare the motility of human spermatozoa cryopreserved using four different methodologies of cooling and warming: cryoloops, droplets, open-pulled straws and standard open straws. Evaluation of two parameters, motility and viability rate of spermatozoa, suggests that all four methods are suitable for use in assisted reproductive technology. However, only the use of open-pulled straws as well as standard open straws allows the isolation of spermatozoa from liquid nitrogen with low potential risk of microbial contamination during freezing and storage, and is thereby a clean method of vitrification.

Abstract
BACKGROUND The influence of silicone templates, used for compartmentalization of culture dishes, on progesterone accumulation in granulosa cell cultures is studied and compared with the effect of paraffin oil, which is frequently used to cover oocyte/embryo cultures. METHODS Human granulosa-lutein cells were cultured in culture dishes compartmentalized by silicone templates, or in polystyrene plates under paraffin oil. Progesterone concentrations in the culture supernatant were compared with controls cultured in polystyrene plates. RESULTS The progesterone concentration in culture supernatant was grossly reduced in silicone template cultures (2+/-0.7% of control). No inhibitory activity was identified in medium conditioned by preincubation with silicone rubber, but progesterone was absorbed from spiked medium incubated in silicone templates (recovery <2%). Progesterone concentration in culture supernatant was also reduced by a paraffin oil overlay (38+/-3% of control). From steroid spiked microdrops under oil, <2% of progesterone and 85+/-4% of estradiol was recovered. CONCLUSION The steroidogenesis of cells cultured in silicone templates or under oil cannot be assessed correctly. It has to be considered that the concentration of lipophilic compounds may be grossly changed due to absorption by silicone rubber or paraffin oil.

Abstract
BACKGROUND This study compared the viability of human pronuclear oocytes subjected to vitrification followed by post-thaw step-wise removal of cryoprotectants versus direct rehydration, in terms of their subsequent in vitro survival and ultrastructural features. METHODS A total of 115 three-pronuclei stage oocytes were cryopreserved in super-open-pulled straws by vitrification in 40% ethylene glycol + 0.75 mol/l sucrose for either 1 min or 10 s at 38 degrees C, followed by direct plunging into liquid nitrogen. After thawing, oocytes vitrified for 1 min (group 1) or 10 s (group 2) were expelled into a graded series of sucrose solutions (1.0, 0.75, 0.5, 0.25 and 0.12 mol/l) for removal of the cryoprotectant in five 2.5 min steps. A second batch of oocytes vitrified for either 1 min (group 3) or 10 s (group 4) were directly expelled into culture medium at 38 degrees C after thawing. Finally, the ultrastructural changes occurring in oocytes in each of the treatment groups were evaluated. RESULTS Oocyte development (division to two-blastomere stage) rates after in vitro culture were 82, 83, 0 and 0% for groups 1, 2, 3 and 4, respectively. The harsh osmotic process involved in direct rehydration provoked ultrastructural changes, including the disruption of cytoplasmic and pronuclear membranes as well as intracellular organelles. CONCLUSION The direct post-thaw rehydration of human pronuclear oocytes has lethal osmotic effects, such that protocols for vitrifying human pronuclear oocytes should include the step-wise removal of the cryoprotectant.

Abstract
OBJECTIVE In this study, we sought to evaluate characteristics of couples with spontaneous conceptions after treatment with assisted reproductive technologies (ART). STUDY DESIGN Data from 254 couples who underwent 1127 therapy cycles between November 1987 and February 1997, were analyzed. Chi-Square (chi(2)) test and Student's t-test were used. P<0.05 was considered significant. RESULTS Spontaneous pregnancies occurred in 14% of all treated couples. Psychological counselling only was performed in 21% but was observed significantly more frequently among patients without later spontaneous conception. Ten percent of all treated couples applied for adoption. The miscarriage rate was significantly higher in the group of treatment dependent pregnancies compared to the group of patients with later spontaneous conception (27% versus 9%). The spontaneous conception rate differed significantly depending on women's age and normal semen analysis. CONCLUSION Appearance of spontaneous conception after ART-procedures should be taken into account in the first patient's interview. Depending on women's age and andrological parameters, treatment-success will differ. The positive impact of psychological counselling for stress relief during and after therapy should also be noted, even though a statistically significant impact could not be demonstrated in the present study. Adoption should be discussed as an alternative to overcome infertility.

Abstract
OBJECTIVE To evaluate the effect of reproductive history on the outcome of different procedures in assisted reproductive technologies (ART) comparing IVF, ICSI, and cryopreserved embryo transfer (CPE). DESIGN Prospective registration of ART cycles and their outcomes. SETTING One hundred three reproductive programs in Germany. PATIENT(S) Women undergoing 174,909 ART procedures from January 1998 through December 2000. INTERVENTION(S) Data analysis of reproductive history collected by the German IVF Registry; multiple logistic regression modeling of success rates. MAIN OUTCOME MEASURE(S) Effect of type of conception and outcome of previous pregnancies, duration of infertility, female's age, and type of ART on clinical pregnancy rate per retrieval. Odds ratios with 95% CIs are reported. RESULT(S) More than one previous pregnancy was negatively correlated with outcome of IVF, ICSI, or CPE. This association disappeared when female age was restricted to a maximum of 35 years. A previous pregnancy achieved by spontaneous conception had less impact on outcome of IVF, ICSI or CPE outcome than did a previous assisted conception. Previous live births and miscarriages demonstrated a statistically significant increase compared with ectopic pregnancies and induced abortions. CONCLUSION(S) Reproductive history must be considered when counseling subfertile couples. Female age, method of conception, and previous pregnancy outcome have a significant effect on IVF, ICSI, and CPE outcome.

Abstract
We studied the influence of recombinant follicle-stimulating hormone (rFSH) stimulation on the concentration of leptin, vascular endothelial growth factor (VEGF), insulin-like growth factor 1 (IGF-1) and insulin-like growth factor binding protein-3 (IGFBP-3) in serum and follicular fluid (FF) in women undergoing assisted reproduction. To test the hypothesis that these hormones could predict successful implantation and that the levels correlate with pregnancy rate. Sequential serum samples were drawn at the beginning of stimulation and on the day of embryo transfer (ET) from 84 women undergoing IVF. The follicular fluid (FF) obtained during oocyte retrieval was collected and the concentration of leptin, VEGF, IGF-1 and IGFBP-3 were measured in all samples. The hormones were measured by commercially available IRMA, RIA or EIA. Patients' characteristics and results of the assisted reproductive cycles were registered. Serum concentrations of VEGF, IGF-1 and IGFBP-3 significantly decreased during rFSH treatment. In contrast, serum leptin significantly increased after rFSH treatment. A strong correlation was found between the FF - levels of IGF-1, IGFBP-3, leptin and respective serum levels. With regard to IVF outcome, higher serum concentrations of IGF-1, IGFBP-3 and VEGF on the day of oocyte retrieval were observed in conception cycles vs. non-conception cycles. No such difference, however, was apparent at the beginning of the stimulation cycle. There was no association between FF levels of any of these hormones and IVF outcome. Our results demonstrate that VEGF, IGF-1, IGFBP-3 and leptin levels are affected by rFSH during controlled ovarian hyperstimulation and that there is a direct association between serum and FF levels, albeit without clinical implications

Abstract
In Germany the application of assisted reproductive techniques (ART) is regulated by federal legislation. Compared with the international situation the "German Embryo Protection Law" is very "restrictive" and various methods of ART are prohibited, e.g. oocyte/embryo donation, embryo cryopreservation and Preimplantation Genetic Diagnosis (PGD). Furthermore, in Germany only 1 to 3 fertilized oocytes may be cultured to embryo. All these embryos then have to be transferred into the uterus of a particular patient. Additional fertilized oocytes can only be cryopreserved in a pronuclear state. The success rate of ART has increased significantly over the past few years owing to the introduction of blastocyst cultures and the selection of 1 to 2 good quality blastocysts for embryo transfer. Furthermore, the transfer of only 1 to 2 blastocysts effectively reduces the risk of high rank multiple pregnancies. In Germany, however, the selection of only a few good quality blastocysts for transfer is prohibited by law. New laboratory techniques, e.g. pronuclear scoring and polar body biopsy screening for aneuploidy are in accordance with German law. The application of these methods provides a selection of "good quality oocytes" and seems to increase the overall success rate. Further studies are required, however. The success rate, quality and cost effectiveness of ART in Germany appears compromised when compared with many other countries. What is more, in contrast to the international situation research and development in ART in Germany has been decreasing constantly over the past few years, due to the inappropriate regulations of the German health care system and the insufficient support given to university-based centers.

Abstract
OBJECTIVES To assess the success of in vitro fertilization when embryos were transferred with low or high fluid volume. STUDY DESIGN A total of 191 consecutive embryo transfer cycles were performed with low (15-20 microl, n=94) or with high (40-50 microl, n=97) fluid volume at an University-based IVF center. In a retrospective analysis, differences in the pregnancy rate were compared by the two-tailed t-test. RESULTS There was no significant difference with regard to patients' age, number of previous attempts, number of oocytes recovered and fertilization rate. Compared to low fluid volume, a high volume for loading the transfer catheter resulted in significantly higher pregnancy (40% versus 23%, P=0.012) and implantation rate (24.4% versus 14.7%, P=0.011). CONCLUSIONS For transfer of embryos on day 3 the amount of fluid volume for transfer has a significant impact on pregnancy and implantation rates.

Abstract
AbstractBackground: It has been shown that a high percentage of interleukin-8 (IL-8) in blood is cell associated. Recently, a simple method for determination of cell-associated IL-8 in whole blood after cell lysis has been described. The purpose of this study was to evaluate this method, to examine the influence of preanalytic sample handling, and to establish the concentration range of total IL-8 and its relation to age and sex in healthy subjects.Methods: Total IL-8 content of whole blood was determined after lysing blood cells with Milenia® cell lysis solution. IL-8 in the resulting blood lysate was measured with the IMMULITE® IL-8 immunoassay.Results: When freshly drawn blood was stored up to 48 h on ice, no significant changes in total IL-8 were measured in the subsequently prepared lysate, whereas with storage at room temperature, total IL-8 increased after 3 h from 94 ± 13 ng/L to 114 ± 16 ng/L (n = 10). In lysate stored for 48 h at 4 °C, marginal changes of the IL-8 concentration were noted, with storage at room temperature, only 76% ± 5% (n = 12) of initial concentration was recovered. From lysate frozen at −20 and −80 °C, respectively, 84% ± 4% and 93% ± 2% of initial IL-8 was recovered after 70 days (n = 10). IL-8 was measured with comparable precision in plasma (CV, 3.2–4.2%) and blood lysate (CV, 3.7–4.1%). When plasma was diluted with cell lysis solution, a slightly overestimated recovery (125% ± 3%) was observed; for lysate specimens with a cell lysis solution content ≥75%, the recovery after dilution was 98% ± 2%. In lysate prepared from 12 blood samples with exogenous IL-8 added, IL-8 recovery was 104% ± 2% (recovery from plasma <35%). The median total IL-8 in blood lysates from 103 healthy subjects (22–61 years) was 83 ng/L of blood (2.5–97.5 percentile range, 49–202 ng/L of blood). In females but not in males, total IL-8 increased significantly with advancing age (P <0.002). We found grossly increased total IL-8 in six pregnant women with amniotic infection syndrome.Conclusions: The evaluated method allows the assessment of total IL-8 in blood with good performance when appropriate conditions of sample pretreatment are considered. The values in healthy volunteers all were above the detection limit of the IL-8 assay; therefore, slight changes of total IL-8 could be noted. Thus, the present method is a suitable tool to study the diagnostic relevance of total IL-8 in blood.
