Background: In recent years the use of silver nanoparticles (AgNP) has increased significantly being focused on assessing human health and environmental risks of nanotechnology.Methods: Research (two series) has been done on white laboratory mice. One dose (20 mg/kg) has been investigated. Frequency of treatment: one time per day for 10 times. Material for the study (ovaries, tubes and uterus) was taken under anesthetic anesthesia on the 10/11th, 21/22nd, 33/34th, 42/43rd days (after the last treatment). Oocyte meiotic maturation, pre- and post-implantation mortality of embryos under ten-time intravenous treatment of AgNP were investigation.Results: Under the ten-time treatment of AgNPs, the inhibition of reproductive function in female mice occurs: a decrease in the number and quality of ovarian oocytes; after male mice were planted, the females do not get pregnant to 21/22 day. The reproductive function in experimental animals is restored on the 40th day after the last treatment with AgNPs; there is no differences between the values of pre- and post-implantation mortality of embryos on the 33/34th day after male mice were planted; in one of the three experimental animals, 7 live pups were born on the 42/43rd day after the male was planted (in animals of the control group during this period: twice (6 ± 1 (n = 6) live pups).Conclusions: In mice females, under a ten-time treatment of AgNPs, the inhibition of reproductive function takes place; with the termination of the AgNPs treatment, the reproductive function is restored.

Background: recently, it has been proved that copolymers with dextran cores and grafted polyacrylamide are effective in photodynamic and chemotherapy. However, further research is needed to define correct dosage and to assess the risks. Thus, animal studies are becoming more relevant to determine the effect of the treatment of such drug nano-systems on female reproductive function in particular.Methods: a technique for estimation of pre- and post-implantation death rates, in vitro meotic maturation of oocytes, double fluorescent vital assay and statistical analysis were used. The effects of a one-time treatment of different doses of dextran-polyacrylamide matrices and silver (Ag)-nanoparticles-dextran-polyacrylamide (AgNPs-D-PAA) on reproductive function, namely on 1) the number of oocytes isolated from one ovary and the meiotic maturation of such oocytes in vitro; 2) the indicators of cell viability of the cells of follicular environment of oocytes (FEO) and the cells of inguinal lymph nodes (ILN); 3) the pre- and post-implantation mortality rates and the number of live newborns (pups) were investigated in female mice.Results: no significant changes in the number of oocytes isolated from one ovary and meiotic maturation of such ovarian oocytes in vitro, the number of living cells of follicular environment of oocytes  and the number of such cells with morphological signs of apoptosis and necrosis, pre- and post-implantation mortality rates of embryos and the number of live newborns (pups) have been established under conditions of one-time treatment with dextran-polyacrylamide at doses of 0.39 mg/kg and 3.90 mg/kg and Ag-nanoparticles-dextran-polyacrylamide at doses of 0.20 mg/kg and 2.00 mg/kg.Conclusions: branched polymer systems (dextran-polyacrylamide (D-PAA) polymer matrices) are promising materials for use in next-generation medicine.

Background: The use of silver nanoparticles (AgNP) has increased very significantly in recent years the work in science is currently on focused on assessing human health and environmental risks of nanotechnology. The aim of the present study was to estimate the functional status of the female reproductive system in mice under condition of the intravenous treatment of silver nanoparticles (AgNPs), namely to assess meiotic maturation of oocytes, viability of follicular cells surrounding the oocyte, spontaneous contractile activity of the myometrium and pre-and post-implantation mortality of embryos.Methods: Research (two series) has been done on white laboratory mice (8 weeks, 16-18 g). AgNPs are spherical nanoparticles of 30 nm (8 mg/ml for metal) diluted in water for injection. Method of treatment: intravenous. Two doses (2 mg/kg and 4 mg/kg) have been investigated. Frequency of treatment: one time per day with each dose of 1, 5 and 10 times (n=10 animals in each group). Material for the study (ovaries, uterus) were taken the day after the last AgNPs injection.Results: Ten-time AgNPs treatment (2 mg/kg and 4 mg/kg) results in inhibition of oocytes meiotic maturation in mice; a single- and five-time AgNPs treatment (2 mg/kg and 4 mg/kg) increases the number of apoptotic cells, while the ten-time AgNPs treatment results in an increase of the apoptotic and necrotic follicular cells surrounding oocytes; for the five-and ten-time AgNPs treatment (4 mg/kg) the index of contractility (IC) of the uterus increased; for the ten-time AgNPs treatment (2 mg/kg and 4 mg/kg) no differences in value of the embryonic mortality between control and study groups have been observed.Conclusions: This study suggests that the development of nanomaterials should be safer and non-toxic and the potential reprotoxicity of AgNPs should be investigated more carefully.

Background: Coenzyme Q10 (CoQ10) and Lepidium sativum (LS) have therapeutic effects on infertility. Objective: To evaluate the combined effects of LS and CoQ10 on reproductive function in adult male NMRI mice. Materials and Methods: Eighty three-months-old male mice (35–40 gr) were divided into four groups (n = 10/each): control (treated with water), CoQ10-treated (200, 300, and 400 mg/kg/body weight), LS-treated (200, 400, 600 mg/kg/body weight), and co-treated (LS [600 mg/kg/body weight] + CoQ10 [200 mg/kg/body weight]) groups. Serum testosterone, luteinizing hormone, follicle-stimulating hormone, and gonadotropin realizing hormone (GnRH) levels were measured using ELISA method. The sperm quality was assessed using Sperm Class Analyzer® (SCA) CASA system and GnRH mRNA expression levels were evaluated by real-time polymerase chain reaction. Results: The number of sniffing and following behavior was significantly higher in LStreated (400 and 600 mg/ml/body weight) groups than the control group (p = 0.0007 and p = 0.0010, respectively). The number of mounting and coupling behaviors was significantly higher in the CoQ10 (300 and 400 mg/ml/body weight)-treated animals than the control group (p = 0.0170 and p = 0.0006, respectively). Co-treatment of CoQ10 (200 mg/ml/body weight) and LS (600 mg/ml/body weight) significantly increased all aspects of sexual behaviors as well as the levels of serum testosterone (p = 0.0011), luteinizing hormone (p = 0.0062), and follicle-stimulating hormone (p = 0.0001); sperm viability (p = 0.0300) and motility (p = 0.0010); and GnRH mRNA levels (p = 0.0016) compared to the control group. Conclusion: The coadministration of CoQ10 and LS significantly improves the activity of the hypothalamic-pituitary-gonadal axis and enhances the reproductive parameters in adult male mice. Key words: Lepidium sativum, Coenzyme Q10, Infertility, Male reproductive function.

Oocyte Meiotic Maturation

In vitro synchronization of oocyte nuclear and cytoplasmic maturation has been found to improve the IVF rate of ovarian oocytes in several species, including humans, in comparison with nonsynchronized in vitro-matured oocytes. Here, we tested the hypothesis that synchronization of oocyte meiotic maturation by an in vivo system in superovulated mice would increase the oocyte fertilization rate when compared to that of conventional superovulated oocytes. Recently, we observed that cilostazol (CZL), a PDE3-I, was able to inhibit mouse oocyte meiotic maturation in both in vitro and in vivo systems. Administering CZL at 7.5 mg, 4 or 7 h pre-hCG allowed retrieval of ovulated oocytes of which >95% were at MI stage, scored by Nikon stereo microscope (SMZ 1500). A conventional superovulation program was adapted in all treated and their control groups, in which mice were injected with eCG and after 48 h with hCG (7.5 IU for each hormone). On the second morning, 13 to 14 h post-hCG, mice were killed and oocytes were collected from oviducts and in vitro fertilized (control). For the treated groups, CZL was administered in a single 7.5 mg oral dose (gavage) 4 or 7 h before the hCG injection. On the second morning, CZL-treated animals were killed at the same timing as control animals and oocytes were retrieved from the oviduct and in vitro matured for 6 h (for those gavaged with CZL, 4 h pre-hCG) or 3 h (for those gavaged with CZL, 7 h pre-hCG) to MII oocytes before IVF. These groups were designated as in vivo-in vitro synchronized/matured oocytes. In other groups treated with CZL, 4 or 7 h pre-hCG, the ovulated oocytes were allowed to mature in the oviduct (full in vivo synchronization and maturation) and oocytes were retrieved and fertilized with the same fertilization timings as the in vivo-in vitro synchronized/matured oocytes. Oocytes were cultured for 1 day after IVF and examined for cleavage. Statistical differences were analyzed by cross-tabulated chi-square test. The full in vivo synchronization and maturation (for both CZL dose timings of 4 and 7 h pre-hCG) gave significantly higher early embryonic development rates compared with those of the control [89% (n = 219) and 92.2% (n = 374) vs 81.8% (n = 198); P = 0.034 and P < 0.0001, respectively]. The in vivo-in vitro synchronized/matured oocytes (CZL dose timing at 7 h, but not 4 h pre-hCG) gave significantly higher early embryonic development rates compared with those of the control [88.5% (n = 339) vs 83.4% (n = 458), respectively; P = 0.043]. However, the increase of the IVF rate of the oocytes from mice treated with CZL, 4 h pre-hCG, in the in vivo-in vitro synchronized/matured group was not significantly different from the control group [88.5% (n = 399) vs 83.4% (n = 458), respectively; P = 0.43]. It is concluded from the present study that synchronization of oocyte meiotic maturation by the in vivo and in vivo-in-vitro protocols can increase the IVF rate of oocytes in superovulated mice.

Andrographolide (AG) is a diterpenoid lactone isolated from the stem and leaves of Andrographis paniculata Nees that is used for the effective treatment of infectious diseases in Asian countries. Previous studies have reported adverse effects of AG on female fertility in rodents; however, the underlying mechanisms are unknown. The aim of the present study was to investigate the effects of AG on the IVM of mouse oocytes and their fertilisation potential. Immature oocytes incubated for 6, 14 or 24 h in medium containing 5, 10 or 20 μM AG showed time- and dose-dependent decreases in maturation rates compared with the control group. Immunostaining revealed that AG exposure disrupted spindle organisation and migration, as well as actin cap formation and cytokinesis. Furthermore, most oocytes exposed to 20 μM AG underwent apoptosis, and the few oocytes exposed to 5 or 10 μM AG that reached MII exhibited lower fertilisation rates after intracytoplasmic sperm injection. The findings of the present study suggest that AG may disrupt mouse oocyte meiotic maturation by blocking cytoskeletal reorganisation, and may thus have an adverse effect on female fertility.

Abstract It is known that L-ascorbic acid (vitamin C) can modulate many biochemical processes intracellularly or extracellularly as antioxidant. The aim of the present study was to examine the effects of media supplementation with ascorbic acid on canine oocyte meiotic maturation, viability and the cumulus cell expansion. Various concentrations of ascorbic acid supplemented in in vitro maturation (IVM) media were tested. Canine oocyte was exposed to different levels of ascorbic acid (0, 50, 150, 250, 500, 750µM). Cumulus expansion, meiotic maturation and degeneration of oocytes were assessed 72 h after in vitro culture. As results, on the group treated with 250µM ascorbic acid was a significant difference compared to the control group on nuclear maturation in stages metaphase I (MI) and metaphase II (MII) (26.98% vs. 6.00%). The groups treated with 50, 150, 250, 500µM had an increase in stage (GVBD), and a significant decrease of degenerate-undefined oocytes compared with the control (23.31%, 18.85%, 13.41% vs 40.80). Concentration 750µM had similar effect to that in the control group. The groups treated with 50, 150, 250, 500µM had an increase in meiosis resumption(GVBD), metaphase I (MI) and metaphase II (MII) with the best result in the group treated with 250 µM ascorbic acid.

Abstract Objective Study of embryotoxicity, teratogenicity and reproductive toxicity of the new drug Lipophtalocyan in rats. Material and Methods Studies were conducted on 210 non-inbred female rats and 105 non-inbred male rats. The drug was administered daily via i. v. injection for 48 days (males) and for 15 days (females) in 2 total doses corresponding to the therapeutic dose (TD) for mice when converted to rats and 10 TD. Results and Conclusion When mating with intact female rats, no changes in sexual behavior were observed, but the index of the ability to fertilize and conceive decreased when compared to the values of the control group by 35–40% (TD index=60%) and by 75–80% (10 TD index=20%). The index of the ability to fertilize and conceive differed from the values of the control group by 90% (TD index=5%) and by 15% (10 TD index=80%). There were no differences in the indicator of embryotoxicity and teratogenicity in intact and drug-treated female rats, compared with the control group. Lipophtalocyan has a negative effect on the male and female reproductive function in rats and has an embryotoxic effect according to the index of the ability to fertilize and conceive, as well as the indices of preimplantation and post-implantation fetal death. The drug does not have a teratogenic effect, neither it affects the physical development of offspring or the rate of maturation of sensory-motor reflexes during feeding.
