Methods: We conducted a systematic review of all published papers on MERS-CoV and SARS-CoV-2 infections in pregnant women in Saudi Arabia to identify knowledge gaps. Inclusion and exclusion criteria were based on the PRISMA system. The search included all papers which were published between September 1, 2012 and November 29, 2020 on pregnant women with MERS-CoV and/ or COVID-19 in Saudi Arabia. Of 26 papers screened, five were included in the analysis. Results: A total of 11 pregnant women with MERS-CoV and four with COVID-19 were reported in Saudi Arabia in the medical literature during the review period. The mean ages of the women were 33 and 31 years old for MERS-CoV and COVID-19, respectively. Maternal and fetal mortality in cases of MERS-CoV were 35% and 30%, respectively, while no maternal or fetal mortalities were reported in COVID-19 cases. Conclusions: Very limited data has emerged from Saudi Arabia on pregnant women MERS-CoV and COVID-19. With such high mortality observed with MERS-CoV compared to COVID-19, there is a need for greater reporting of cases to truly grasp the extent of these infections in pregnant women in a country where both coronaviruses are circulating.","PeriodicalId":8564,"journal":{"name":"Asian Pacific Journal of Reproduction","volume":"10 1","pages":"97 - 101"},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44376813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: All the 21 crossbred Large White Yorkshire sows were considered in the study period starting at day 1 of current farrowing when the feeding of specific supplemental ration was started until the day of subsequent farrowing (days 150-155) and were equally allocated into three groups. Group 1 served as the control group and followed their normal feeding schedule. Group 2 and group 3, in addition to their normal feeding schedule, were supplemented with flaxseed at a rate of 0.5% and 1.0% of the dry matter, respectively. Blood samples were collected 15 days prior to farrowing, on the day of farrowing (day 0), at weekly intervals until day 28 of lactation and at monthly intervals during gestation to harvest the plasma. Plasma was used to assess the metabolic and endocrine status of sows. Body weight of each sow and individual birth weight of all piglets born were measured. Results: Flaxseed supplementation led to decrease in plasma cholesterol and triglyceride levels in the supplemented groups than in the control group (P<0.05). Plasma estradiol-17β level was higher in group 2 than that in group 1 and 3 on day 90 of the gestation period (P<0.05). The mean plasma level of insulin-like growth factor 1 was higher in group 3 than that in group 1 and 2 both in late lactation (day 28) as well as in early gestation (day 30) (P<0.05). Plasma NEFA and weight gain were greater in sows of group 2 and 3 compared to those fed with the normal control diets (P<0.05). The proportion of pregnant sows relative to sows bred was 100.0% in group 2 and 3 and 85.7% in the control group. Piglet mortality was lower in group 2 and 3 compared to group 1 (P>0.05).

Methods: Twenty-four female C57BL/6NTac mice, aged 12-16 weeks, were randomly divided into four groups. Group A did not receive any treatment and served as the control group. Group B was treated with corn oil stripped of tocopherols and served as the vehicle group. Group C was treated with 60 mg/kg body weight of tocotrienol-rich-fraction with corn oil stripped of tocopherols. Group D was treated with 60 mg/kg body weight of alpha-tocopherol with corn oil stripped of tocopherols. All treatments were administered orally for 7 consecutive days. After superovulation and mating with fertile males, 2-cell stage embryos were harvested for vitrification. Post vitrification development in vitro, gross morphology and ultrastructure were compared between groups. Results: The number of 2 and 8-cell embryo, and blastocysts in the treatment and control groups were not significantly different (P>0.05). Following vitrification, all 2-cell embryos had equal-sized blastomeres and intact zona pellucida. Mitochondrial aggregation toward the perinuclear region was seen in all of the treatment groups. Both groups C and D had vacuolated mitochondria, which was reflected in the trend of preimplantation development reduction. Conclusions: Vitamin E supplementation of 60 mg/kg body weight does not improve the viability of healthy embryos according to this study. As a result, the most effective dose of vitamin E supplementation may be determined by the initial quality of the embryos.","PeriodicalId":8564,"journal":{"name":"Asian Pacific Journal of Reproduction","volume":"10 1","pages":"137 - 144"},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45292120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, iodine-induced thyroid dysfunctions namely hyperthyroidism, hypothyroidism, autoimmune thyroid diseases, endemic goiter and even thyroid cancer including infertility, still births, abortions and embryo toxicity have emerged as a major public health problem. In other words, the consequence of iodine deficiency and excess is almost ‘U’-shaped. Hypothyroidism caused by iodine deficiency affects reproductive functions of organisms; however, such undesirable effects of iodine overload on male gonadal physiology together with hormonal profiles are yet to be adequately explored. The discovery of iodide transporter in the testis justifies an independent role of iodine in male reproductive function, which is not entirely known. Recent studies on human subjects and animal models are now revealing further perceptions into the effect of excess iodine on male infertility with euthyroid status. Excess iodine exposure has been linked with deterioration of structural and functional changes of testis leading to compromised spermatogenesis by affecting various cellular and molecular signaling pathways culminating into disrupted the blood-testis barrier and cytoskeleton. This review provides an update and summarizes various novel insights of excess iodine exposure on reproduction by establishing the independent role of iodine on male reproductive endocrinology, which might help in formulating future strategies to prevent iodine-induced male infertility, an emerging global concern, especially in the post-salt iodization era.","PeriodicalId":8564,"journal":{"name":"Asian Pacific Journal of Reproduction","volume":"10 1","pages":"102 - 112"},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41361473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Thirty six healthy female Wistar rats with regular estrus cycles were randomly divided into six groups each of 6. Group I received 1 mL of 0.5% carboxyl methyl cellulose orally and served as the vehicle control group, while groups II to VI were treated with letrozole (1 mg/kg body weight p. o.) for 21 days to induce PCOS. After induction of PCOS, group II served as the PCOS control group, without treatment; group III received metformin (20 mg/kg body weight p. o.) as the standard group, and groups IV to VI received G. sylvestre (100 mg/kg body weight p. o.), P. daemia (300 mg/kg body weight p. o.), and the combination of G. sylvestre and P. daemia, respectively, for 28 days. Vaginal smears were collected from all rats daily throughout the study to determine the phases of the estrus cycle. After completing the treatment schedule, oral glucose tolerance test, serum lipid profile and reproductive hormonal analysis were carried out. Subsequently, the rats were sacrificed to collect ovary and uterus for histopathological examination. Results: The PCOS control rats showed a significant irregularity in the estrus cycle, hyperglycemia, and the altered serum lipid profile such as the increased low and very low density lipoprotein, triglyceride, and decreased high density lipoproteins. In addition, the PCOS control rats showed a significant increase in serum luteinizing hormone, testosterone, and estrogen, and decrease in follicle stimulating hormone and progesterone. These changes were significantly revoked in all the treatment groups. The test drugs also significantly reduced the gained ovary weight (P<0.001), and histopathology of the ovary showed almost normal ovary. Among the treatment groups, the group of combination treatment of G. sylvestre and P. daemia showed superior ameliorative results in PCOS parameters.

Methods: Two independent experiments (6 replicates each) were carried out to evaluate gilt oocyte maturation, and fertilization and embryonic development by using ovaries from a local abattoir. Totally, 712 oocytes were randomly distributed in four-well dishes to receive Novormon (eCG 5.0 IU), PG600 (eCG 5.0 IU and hCG 2.5 IU), Chorulon (hCG 5.0 IU), or no hormones. Oocytes were incubated with 5% CO2, 95% air and saturation humidity at 39 °C for 44 h. Maturation of the oocytes to metaphase II was assessed by using the aceto-orcein technique. In addition, 741 oocytes were used and randomly distributed in four-well dishes, and then oocyte maturation was carried out as mentioned, but matured oocytes were washed and placed in fertilization medium with frozen-thawed sperm. Gametes were co-incubated for 7 h, and then washed and placed in development medium, and incubated for further 7 days, at which time embryonic development was evaluated. Fertilization and embryo development media were not supplemented with the studied hormones.

In testicular function study, a total of 24 male guinea pigs were randomised into 4 groups of 6 guinea pigs each. Group A (control) were orally administered 1 mL of physiological saline, once daily for 60 days while groups B, C and D were treated like the control group except that they were orally administered 100, 250 and 500 mg/kg body weight of ethanol extract of S. mombin leaves. For the fertility study, the same animal groupings and treatments in the testicular function study were adopted. The male guinea pigs were paired with the females (1:1) and afterwards examined for pregnancy outcomes. Results: The ethanol extract of S. mombin leaves contained saponins, alkaloids, flavonoids, tannins, steroids, phenolics, phlobatannins, cardiac glycosides, cardenolides and dienolides with saponins (4.80 mg/mL) occurring the most whilst cardenolides and dienolides (0.08 mg/mL) were the least. The ethanol extract of S. mombin leaves significantly and dose dependently reduced the activities of alkaline phosphatase, glutamate dehydrogenase, 3-hydroxy-3-methylglutaryl coenzyme A reductase, malic enzyme, 17-β-hydroxysteroid dehydrogenase, lactate dehydrogenase, catalase and superoxide dismutase as well as levels of testosterone, glycogen, total protein and ascorbic acid in the testes when compared with the control group (P&lt;0.05). All the doses of ethanol extract of S. mombin leaves also reduced the levels of sorbitol dehydrogenase, 3-β-hydroxysteroid dehydrogenase, glucose-6-phosphate dehydrogenase and sialic acid whereas the levels of testicular acid phosphatase, gamma glutamyl transferase and cholesterol increased dose dependently (P&lt;0.05). The serum luteinising hormone, testosterone and estradiol were reduced after the administration of ethanol extract of S. mombin leaves whereas levels of serum follicle stimulating hormone increased significantly.

Methods: In this study, testosterone, as an indicator of the aphrodisiac potential of P. bullata, was investigated for its release from TM3 Leydig cells grown in vitro and in 4 fowls given capsules containing P. bullata at a dose of 10 mg in each capsule twice a day, for 50 days. In the latter in vivo evaluation, mating behaviours were additionally determined after the treated fowls were released to the individual hens, and their testes and liver were dissected for histological examinations. Blood drawn from the fowls was assessed for any changes in diagnostic parameters. Results: In the in vitro test (TM3 Leydig cells), P. bullata was able to increase testosterone to 0.48 nmol/L within 72 h of incubation, compared to the untreated control with only 0.18 nmol/L, i.e., an increase of 170%. In the in vivo test, outcomes in the fowls dosed with P. bullata showed similar positive elevations of testosterone to (9.72±1.10) nmol/L in comparison to the controls that showed a level of only (4.05±0.84) nmol/L. Total frequencies of mating behaviours were observed (wing flapping, body shakes, crowing and beak pecking) to be 23 counts for the test compared to only 15 for the control fowls. Histological examination of the male reproductive organs provided evidence of testosterone boosting based on an observable increase in the activity at the seminiferous tubules of testis tissues without any damaging effects, compared to the controls. In the nine diagnostic blood parameters assessed, including alanine aminotransferase, aspartate aminotransferase, and gamma glutamyltransferase, none was remarkably elevated compared to the controls. The histological changes in the liver were not severe and mainly consisted of only localized moderate but recoverable obstructions and swellings of the vessels and tubules.
