Abstract
Sex determination and differentiation are processes by which a bipotential gonad adopts either a testicular or ovarian cell fate, and secondary sexual characteristics adopt either male or female developmental patterns. In birds, although genetic factors control the sex determination program, sex differentiation is sensitive to hormones, which can induce sex reversal when disturbed. Although these sex-reversed birds can form phenotypes opposite to their genotypes, none can experience complete sex reversal or produce offspring under natural conditions. Promising evidence indicates that the incomplete sex reversal is associated with cell autonomous sex identity (CASI) of avian cells, which is controlled by genetic factors. However, studies cannot clearly describe the regulatory mechanism of avian CASI and sex development at present, and these factors require further exploration. In spite of this, the abundant findings of avian sex research have provided theoretical bases for the progress of gender control technologies, which are being improved through interdisciplinary co-operation and will ultimately be employed in poultry production. In this review, we provide an overview of avian sex determination and differentiation and comprehensively summarize the research progress on sex reversal in birds, especially chickens. Importantly, we describe key issues faced by applying gender control systems in poultry production and chronologically summarize the development of avian sex control methods. In conclusion, this review provides unique perspectives for avian sex studies and helps scientists develop more advanced systems for sex regulation in birds.

Abstract
Estradiol is a steroid hormone excreted from the female gonads, mainly during the pre-estrus. However, the potential effects of estradiol are yet to be explored on sperm parameters through cryopreservation. In this study, we supplemented estradiol, 3 and 5 μM, in the goat semen extender and assessed the sperm parameters after a freeze-thawing process. Sperm motility was assessed using the computer-assisted sperm analysis system. Sperm viability and membrane integrity improved using both 3 and 5 μM concentrations of estradiol. The highest rate of progressive motility was observed in the 3 μM estradiol group. However, a higher concentration of estradiol (5 μM) reduced the progressive motility. Then, we were interested to see if the supportive effect of estradiol on sperm motility is mediated through the intracellular concentration of calcium ionophore. We supplemented the semen extender with 1 and 10 mM ethylenediaminetetraacetic acid (EDTA) and showed that 1 mM has no adverse effect on progressive sperm motility. Then, estradiol (3 μM) was supplemented with or without EDTA (1 mM) into the semen extender. Individual EDTA treatment improved the progressive sperm motility compared to the control group. However, in the presence of estradiol, EDTA treatment reduced the progressive motility compared to the individual estradiol group. This indicated a considerable interaction between estradiol and EDTA for progressive sperm motility. Indeed, EDTA reduced the supportive effects of estradiol on sperm cryopreservation parameters. These results indicated that induction of higher progressive sperm motility in response to estradiol is a calcium-dependent process, as the EDTA did completely abrogate the estradiol-mediated effect.

Abstract
The modified prolonged gonadotropin-releasing hormone agonist (GnRH-a) protocol lessens the ovarian hyperstimulation syndrome (OHSS) effect and improves the clinical pregnancy rate of women with polycystic ovary syndrome (PCOS) compared with the standard long GnRH-a protocol. However, the molecular basis of this process needs to be elucidated. Sprague Dawley (SD) female rats with letrozole-induced PCOS were divided into GnRH-a and blank groups. Rats in the GnRH-a group were given triptorelin for 11 days, whereas those in blank group were given an equal volume of 0.9% NaCl. Meanwhile, the changes in estrus cycle, hormonal profile, ovary index, ovarian histopathology and body weight were measured. The expressions of anti-mullerian hormone (AMH), type II receptor of AMH (AMHRII), and FSH receptor (FSHR) were taken as the indicators of follicular sensitivity. Changes of follicular counting and differences in antral follicle diameter at each stage were evaluated. The number of follicles from primordial to antral stages increased during downregulation and the differences in antral follicle diameter were reduced in the GnRH-a group, whereas no significant difference was found in the blank group. The results of Western blotting and ELISA indicated that the level of AMH in ovarian total protein and serum had a similar dynamic change in the GnRH-a group. The results of immunohistochemistry showed that follicular AMH, AMHRII, and FSHR significantly decreased in the GnRH-a group. Prolonged GnRH-a protocol can improve synchronization and sensitivity of follicular development by balancing the expressions of AMH, AMHRII, and FSHR among follicles at all levels, thereby achieving better therapeutic effect.

Abstract
The technique of delivering various nutrients, supplements, immunostimulants, vaccines, and drugs via the in ovo route is gaining wide attention among researchers worldwide for boosting production performance, immunity and safeguarding the health of poultry. It involves direct administration of the nutrients and biologics into poultry eggs during the incubation period and before the chicks hatch out. In ovo delivery of nutrients has been found to be more effective than post-hatch administration in poultry production. The supplementation of feed additives, nutrients, hormones, probiotics, prebiotics, or their combination via in ovo techniques has shown diverse advantages for poultry products, such as improved growth performance and feed conversion efficiency, optimum development of the gastrointestinal tract, enhancing carcass yield, decreased embryo mortality, and enhanced immunity of poultry. In ovo delivery of vaccination has yielded a better response against various poultry pathogens than vaccination after hatch. So, this review has aimed to provide an insight on in ovo technology and its potential applications in poultry production to deliver different nutrients, supplements, beneficial microbes, vaccines, and drugs directly into the developing embryo to achieve an improvement in post-hatch growth, immunity, and health of poultry. © 2019 Society of Chemical Industry.

Abstract
Insulin-like growth factor-1 (IGF1) and anti-aromatase synergistically increase the rate and stability of female-to-male sex reversal as well as pre- and postnatal weight gains in hatched chickens. This study aimed at assessing gene expression profiles of chicken embryos treated with IGF1 and fadrozole. Day 3.5 fertile eggs were in ovo injected with one of IGF1, fadrozole anti-aromatase, combined IGF1 and fadrozole, or sham injection. The expression profile was studied on day 6 and day 11 of the embryonic development following gonadal differentiation. On day 6 of embryonic development, simultaneous injection of IGF1 and fadrozole significantly upregulated the expression of RSPO1, AMH, and SOX9 in genetically female embryos compared to single injections and control groups. Also, a higher expression of ESR1 and BMP4 was observed in genetically male embryos on day 6 compared to the control group. In day 11 embryos, a higher expression of BMP4 was detected in both males and females of the IGF1 and fadrozole-administered group compared to the sham injection cohort. In conclusion, the results of this study indicate that combined effects of IGF1 and fadrozole induce female-to-male sex reversal by increasing the expression of testis developmental factors rather than attenuating ovary developmental factors.

Abstract
Background Research into energy balance and growth has infrequently considered genetic sex, yet there is sexual dimorphism for growth across the animal kingdom. We test the hypothesis that in the chicken, there is a sex difference in arcuate nucleus neuropeptide gene expression, since previous research indicates hypothalamic AGRP expression is correlated with growth potential and that males grow faster than females. Because growth has been heavily selected in some chicken lines, food restriction is necessary to improve reproductive performance and welfare, but this increases hunger. Dietary dilution has been proposed to ameliorate this undesirable effect. We aimed to distinguish the effects of gut fullness from nutritional feedback on hypothalamic gene expression and its interaction with sex. Methods Twelve-week-old male and female fast-growing chickens were either released from restriction and fed ad libitum or a restricted diet plus 15% w/w ispaghula husk, a non-nutritive bulking agent, for 2 days. A control group remained on quantitative restriction. Hypothalamic arcuate nucleus neuropeptides were measured using real-time PCR. To confirm observed sex differences, the experiment was repeated using only ad libitum and restricted fed fast-growing chickens and in a genetically distinct breed of ad libitum fed male and female chickens. Linear mixed models (Genstat 18) were used for statistical analysis with transformation where appropriate. Results There were pronounced sex differences: expression of the orexigenic genes AGRP (P < 0.001) and NPY (P < 0.002) was higher in males of the fast-growing strain. In genetically distinct chickens, males had higher AGRP mRNA (P = 0.002) expression than females, suggesting sex difference was not restricted to a fast-growing strain. AGRP (P < 0.001) expression was significantly decreased in ad libitum fed birds but was high and indistinguishable between birds on a quantitative versus qualitative restricted diet. Inversely, gene expression of the anorectic genes POMC and CART was significantly higher in ad libitum fed birds but no consistent sex differences were observed. Conclusion Expression of orexigenic peptides in the avian hypothalamus are significantly different between sexes. This could be useful starting point of investigating further if AGRP is an indicator of growth potential. Results also demonstrate that gut fill alone does not reduce orexigenic gene expression.

Abstract
Follicular growth and ovulation of healthy oocytes is a complicated process which is regulated by several endocrine and paracrine factors as well as cross-talk between the oocyte and its surrounding somatic cells. This study compared the expression profile of some candidate genes involved in BMP signaling as well as estrogen and AMPK production in cumulus-oocyte complex (COC) of small and large antral follicles and their associated somatic cell layers in ovaries from ewes with high- and low-antral follicle count (AFC). Expression of GDF9 was increased by increasing the size of antral follicles, while BMP15 expression was decreased by follicular size. It should be noteworthy that transcription of both GDF9 and BMP15 was also detected in the adjacent cellular layers under the follicles. There was a very strong positive correlation between BMP15 and BMPR2 in ovary tissues. Expression of GDF9 was highly correlated with BMP15, BMPR1B, and BMPR2 in large antral follicles. Expression of BMP7 in small antral follicles and BMPR2 in ovary tissues was significantly increased in the high-AFC group. Expression of ESR1 and ESR2 involved in estrogen production as well as PRKAA1 which involved in AMPK production were significantly greater in large antral follicles of high-AFC. There was a very high correlation between Cyp19 and ESR1 in large antral follicles and ovary tissues. Expression of Cyp19 and PRKAA1 were positively correlated with GDF9, BMP15, and BMP7 in large follicles. In conclusion, this study suggests that apart from the BMP signaling, genes involved in AMPK and estrogen production can be pivotal players in ewe's follicular development process. In addition, a strong cross-talk can exist among AMPK, BMP signaling, and estrogen synthesis systems in ewe ovary.

Abstract
DNA uptake in the post-acrosomal region of the spermatozoa takes place exclusively in immotile spermatozoa that are naturally unable to fertilize eggs. The present study aimed to assess whether passive transmission of non-viral vectors to the surrounding areas of chicken embryos could be an alternate mechanism in chicken sperm-mediated gene transfer. First, the presence of nucleases in rooster seminal plasma was evaluated. Semen ejaculates from five roosters were centrifuged and the supernatant was incubated with pBL2 for 1 h. A robust nuclease cocktail was detected in the rooster semen. To overcome these nucleases, plasmid-TransIT combinations were incubated with semen for 1 h. Incubation of exogenous DNA in the lipoplex structure could considerably bypass the semen nuclease effect. Then, intravaginal insemination of 1 × 10(9) sperm mixed with lipoplexes (40 µg pBL2:40 µl TransIT) was carried out in 15 virgin hens. Neither the epithelial tissue from the inseminated female reproductive tracts nor the produced embryos following artificial insemination showed the transgene. To remove any bias in the transgene transmission possibility, the plasmid-TransIT admixture was directly injected in close vicinity of the embryos in newly laid eggs. Nonetheless, none of the produced fetuses or chicks carried the transgene. In conclusion, the results of the present study revealed a nuclease admixture in rooster seminal plasma, and passive/active transmission of the non-viral vector into close vicinity of the chicken embryo was inefficient for producing transgenic chicks.
