Abstract
We evaluated ovarian follicular dynamics in bonnet monkeys by employing trans-abdominal ultrasonography. Following the administration of human follicle stimulating hormone (hFSH) and/or human menopausal gonadotropin (hMG), multiple follicular development was assessed and their numbers, size and growth profiles were monitored. The ultrasonograms showed that the follicular antrum appeared distinctly anechoic with well-defined hyperechoic borders. Depending on the type, quantity (12.5-25IU), and duration (6-9days) of hormones administered, the number of developing follicles was 2-12 per ovary with their lowest diameter being 2mm. With continued hormone administration, their numbers and diameters increased; which were more pronounced in animals administered with hFSH than with hMG, with follicles of 6-8mm. Interestingly, human chorionic gonadotropin (hCG) injection (2000-3000IU), when follicles acquiring >6-8mm sizes, induced the maximum expansion of antral follicles with sizes reaching up to 14mm. On days 3-5 post-hCG, the ultrasonograms showed loosely demarcated multiple hypoechoic structures and well-demarcated hyperechoic structures with anechoic/hypoechoic cores corresponding to unruptured luteinized follicles and corpora lutea, respectively. On day 4 post-hCG, there was a substantial reduction in the number of antral follicles. In stimulated animals, follicular growth, ovulation, and formation of luteal structures were accompanied by corresponding physiological changes in the serum estradiol and progesterone profiles. These findings, for the first time, showed that ultrasonographic imaging approach is useful for precise monitoring of temporal changes in follicular developmental dynamics and to time the hCG induced ovulation in the bonnet monkey.

Abstract
Nonhuman primates (NHP) are the closest animal species to humans and have been widely used for studying human reproductive physiology. Assisted reproductive technology (ART) in Old World NHPs provides great opportunity for studying fertilization, embryo development, embryonic stem cell (ESC) derivation for regenerative medicine, somatic cell nuclear transfer (cloning), and transgenic NHP models of inherited genetic disorders. Here we present two ART protocols developed for rhesus monkey (Macaca mulatta) and baboon (Papio cynocephalus).

Abstract
The vervet monkey was evaluated as a primate model for use in assisted reproductive technologies (ARTs). Eight adult female vervets were hormonally monitored for their potential use as egg donors and those six females displaying regular menstrual cycles were subjected to controlled ovarian stimulation with recombinant human gonadotropins. Three animals failed to respond while laparoscopic follicular aspiration was performed on the other three females at 27-30 h post-human chorionic gonadotropin administration. A total of 62, 40, and 18 oocytes was recovered from these three animals of which 30, 20, and 4, respectively, matured to the metaphase II stage and were subsequently inseminated using intracytoplasmic sperm injection. An average of 40+/-15% (SEM) of the inseminated oocytes were fertilized based on pronucleus formation and timely cleavage. One embryo from each of the two stimulated females developed into expanded blastocysts. Two adult male vervets were assessed as sperm donors. Neither adjusted well to the restraint and collection procedure required for penile electroejaculation. Samples collected via rectal electroejaculation were very low in sperm motility and concentration; however, cauda epididymal aspirations from one male yielded an adequate concentration of motile sperm. These results emphasize the need to establish species-specific ovarian stimulation protocols and semen collection techniques if vervets are to be considered for basic and applied (ARTs) research on primate gametes or embryos.

Abstract
To determine whether phosphodiesterase (PDE) 3 inhibitors prevent the resumption of meiosis by primate oocytes in vivo, rhesus macaques were stimulated to develop multiple preovulatory follicles by administering human recombinant gonadotropins, and follicles were aspirated 34 h after an ovulatory stimulus (human chorionic gonadotropin [hCG]). Monkeys received no further treatment (controls) or the PDE3 inhibitor ORG 9935 (a) exclusively in the periovulatory interval beginning 6-12 h prior to receiving hCG at 200 mg/kg every 12 h orally (PER200) or a 200 mg/kg oral loading dose followed by 50 mg/kg sc every 6 h (PER50) or (b) throughout the ovarian stimulation protocol with daily increases until a dose of 200 mg/kg bid was administered onward from the eighth day of ovarian stimulation (EXT200). The primary outcome was the number of oocytes that had resumed meiosis (germinal vesicle breakdown [GVBD]) at collection. At initial aspiration, 85% of oocytes recovered from control animals (n = 4) had progressed to GVBD compared with 53% (p<.01), 23% (p<.01), and 13% (p<.01) recovered from animals in the PER200 (n = 2), PER50 (n = 1) and EXT200 (n = 3) groups, respectively. Although spontaneous maturation of oocytes was observed during follow-up culture in the absence of ORG 9935, none of the oocytes in the PER50 or EXT200 underwent normal fertilization in vitro. These results demonstrate that the PDE3 inhibitor ORG 9935 blocks oocyte maturation during gonadotropin-stimulated ovarian cycles in rhesus macaques and suggest that PDE3 inhibitors have potential clinical use as contraceptives in women.

Abstract
Detailed molecular studies of preimplantation stage development in a suitable nonhuman primate model organism have been inhibited due to the cost and scarcity of embryos. To circumvent these limitations, we have created a new resource for the research community, designated as the Primate Embryo Gene Expression Resource (PREGER). The PREGER sample collection currently contains over 160 informative samples of oocytes, obtained from various sized antral follicles, and embryos obtained through a variety of different protocols. The PREGER makes it possible to undertake quantitative gene-expression studies in rhesus monkey oocytes and embryos through simple and cost-effective hybridization-based methods. The PREGER also makes available other molecular tools to facilitate nonhuman primate embryology. We used PREGER here to compare the temporal expression patterns of five housekeeping mRNAs and three transcription factor mRNAs between mouse and rhesus monkey. We observed noticeable differences in temporal expression patterns between species for some mRNAs, but clear similarities for others. Our results also provide new information related to genome activation and the effects of embryo culture conditions on gene expression in primate embryos. These results provide one illustration of how the PREGER can be employed to obtain novel insight into primate embryogenesis.

Abstract
Continual administration of low doses of the antiprogestin ZK137316 permits ovarian/menstrual cyclicity, but prevents pregnancy in female rhesus monkeys. The sites of contraceptive action remain unknown. This study determined whether chronic, low-dose antiprogestin exposure during follicular development impairs oocyte maturation in vivo, as well as fertilization and preimplantation embryogenesis in vitro. Adult, female rhesus monkeys exhibiting normal menstrual cycles received vehicle (n=9) or 0.03 mg ZK137316 (n=8)/kg body weight i.m. daily for 3 months. Controlled ovarian stimulation with recombinant gonadotropins was initiated in the 3rd month. Oocytes collected from preovulatory follicles were evaluated for nuclear maturity and inseminated in vitro. Preimplantation embryonic development was monitored in vitro. The total number of oocytes and percentage collected at each nuclear stage were similar in both groups. More (P<0.05) atretic oocytes were recovered following antiprogestin relative to vehicle treatment. Fertilization rates and percentages of embryos that progressed to the morula stage were similar between groups, but antiprogestin-treated females exhibited less (P<0.05) normal cleavage. Embryonic development was accelerated by 1 day (P<0.05) from the 16-cell to the morula stage in the antiprogestin group relative to vehicle. Despite this, the majority of embryos became blastocysts within 6 days in vitro in the antiprogestin group, but fewer expanded (P=0.09) and hatched (P<0.05) compared to vehicle. During in vivo treatment with chronic, low-dose antiprogestin, oocytes retained their ability to resume and complete meiosis as well as fertilize following insemination in vitro. However, preimplantation embryogenesis in vitro was impaired, particularly during the later stages of blastocyst development. Thus, antiprogestin exposure during follicular development altered oocyte functions that are critical for normal preimplantation embryogenesis; this may contribute to pregnancy prevention.

Abstract
During reproductive life, only a selected few ovarian follicles mature and ovulate, while the vast majority of follicles undergo a degenerative process called atresia. Recent studies have indicated that follicular atresia is mediated through apoptosis of follicular granulosa cells. The objectives of the present study were to determine the time of onset of apoptosis in granulosa cells of preovulatory follicles and to evaluate the consequences of gonadotropin withdrawal on mitogen-activated protein (MAP) kinase activities. Bonnet monkeys (Macaca radiata) undergoing controlled ovarian stimulation cycles were utilized for stimulation of multiple follicles, and granulosa cells were retrieved from preovulatory follicles at 24, 48, 72, and 96 h after stopping gonadotropin treatment. Serum and follicular fluid estradiol concentrations were highest at 24 h but declined precipitously (P < 0.05) to reach the lowest concentrations at 96 h; however, progesterone concentrations during this period did not increase, indicating the absence of luteinization. Quantitative analysis of genomic DNA by 3'-end labeling revealed the presence of low-molecular-weight fragments from 48 h onward, but by agarose gel electrophoresis, DNA laddering could be visualized only after 72 h. Messenger RNA expression for Bax, caspase-2, and caspase-3 increased with the onset of apoptosis. Immunoblot analysis of MAP kinases in lysates of granulosa cells (48-72 h) indicated increased (P < 0.05) levels of phosphorylated extracellular response kinase-1 and -2, Jun N-terminal kinase (JNK)-1 and -2, and p38. However, in vitro kinase assay data indicated that only phospho-JNK and -p38 activities were higher at 72 h compared to 24 h. These results demonstrate that granulosa cells of preovulatory follicles undergo apoptosis and that increased activities of phospho-JNK and -p38 are correlated with apoptosis in the primate.

Abstract
To reduce the number of animals required for controlled studies of marmoset oocytes and early embryos, a superovulation protocol was developed for the common marmoset. Females were given up to 50 i.u./day recombinant human follicle stimulating hormone (FSH)--(r-hFSH) for 6 days. Ovaries were visualized by a modified laparoscopic technique and follicular aspiration was performed using a needle and suction apparatus inserted directly through an otoscope speculum. The number of follicles + ovulation points (+/- S.E.) was 2.9 (+/- 0.2) in controls and 14.1 (+/- 1.6; P < or = 0.001) in the 50 i.u. r-hFSH per day animals. Oocytes, typically at the germinal vesicle stage at collection, extruded a first polar body within 26 hours. In vitro fertilization was performed and embryos developed to the hatched blastocyst stage (34%). With many high quality oocytes and the ability to synchronize cycles, the marmoset is a valuable primate model for examining nuclear reprograming and early embryonic events.

Abstract
The goal of this study was to determine if differences exist between in vivo vs. in vitro OGP association with the ZP and to quantitate those differences. Ovarian oocytes were harvested 12.5 or 27 hr post-hCG from hyperstimulated hamsters or baboons, respectively. Hamster and baboon ovarian oocytes were incubated in vitro in media +/- homologous OGP (100 or 200 microg/100 microl) or in some studies with 100 microl oviductal fluid for 3, 6, or 24 hr at 37 degrees C. Some of the baboon ovarian oocytes were transferred immediately after harvesting to the ampulla of both oviducts using a tom cat catheter and retrieved after a 3 hr in situ incubation. Hamster oviductal oocytes were collected 3, 6, and 24 hr following ovulation. After incubation or oocyte retrieval from the oviduct, cumulus cells were removed, oocytes were washed extensively and binding of OGP to the ZP was examined by immunofluorescence. Fluorescence intensity was quantified using densitometric scanning of photographic negatives with the background of each negative as an internal control. In all studies, OGP association with the ZP was significantly greater in vivo than in vitro (P < 0.05). In vitro OGP association with the ZP did not significantly increase with incubation time or OGP concentration; however, a small nonsignificant increase in OGP association with the ZP in the oviduct was detected over time. Differences did not appear to be due to depletion of OGP from the in vitro incubation media, since Western blot analysis of the media showed that OGP was still present. Although OGP concentration in vivo is unknown, Western blots showed similar intensity comparing 100 microg of OGP media and oviductal fluid. Immunolocalization of OGP using laser confocal microscopy showed regional differences in OGP binding. The outer half of the zona pellucida had significantly more OGP bound than the inner half on oviductal oocytes. No regional differences were detected for in vitro incubated oocytes. In conclusion, OGP association with the ZP is greater in vivo vs. in vitro, suggesting that one must be cautious in designing and evaluating in vitro studies of OGP function.
