Abstract
Preventing unintentional pregnancy is one of the goals of a global public health policy to minimize effects on individuals, families, and society. Various contraceptive formulations with high effectiveness and acceptance, including intrauterine devices, hormonal patches for females, and condoms and vasectomy for males, have been developed and adopted over the last decades. However, distinct breakthroughs of contraceptive techniques have not yet been achieved, while the associated long-term adverse effects are insurmountable, such as endocrine system disorder along with hormone administration, invasive ligation, and slowly restored fertility after removal of intrauterine devices. Spurred by developments of nanomaterials and bionanotechnologies, advanced contraceptives could be fulfilled via nanomaterial solutions with much safer and more controllable and effective approaches to meet various and specific needs for women and men at different reproductive stages. Nanomedicine techniques have been extended to develop contraceptive methods, such as the targeted drug delivery and controlled release of hormone using nanocarriers for females and physical stimulation assisted vasectomy using functional nanomaterials via photothermal treatment or magnetic hyperthermia for males. Nanomaterial solutions for advanced contraceptives offer significantly improved biosafety, noninvasive administration, and controllable reversibility. This review summarizes the nanomaterial solutions to female and male contraceptives including the working mechanisms, clinical concerns, and their merits and demerits. This work also reviewed the nanomaterials that have been adopted in contraceptive applications. In addition, we further discuss safety considerations and future perspectives of nanomaterials in nanostrategy development for next-generation contraceptives. We expect that nanomaterials would potentially replace conventional materials for contraception in the near future.

Abstract
While hormonal contraceptives are efficacious and available in several forms for women, perception of safety and concern over side effects are a deterrent for many. Existing non-hormonal contraceptives include permanent sterilization, copper intrauterine devices (IUDs), chemical/physical barriers such as spermicides and condoms, as well as traditional family planning methods including withdrawal and the rhythm method. Individuals who wish to retain their fertility in the future can achieve highest adherence and efficacy with long-acting, reversible contraceptives (LARCs), though there is only one, the copper IUD, that is non-hormonal. As rates of unintended pregnancies remain high with existing contraceptive options, it is becoming increasingly attractive to develop novel pregnancy prevention methods for both women and men. Non-hormonal contraceptives can target a variety of critical reproductive processes discussed here. This review focuses on identified non-hormonal contraceptive targets and subsequent drug candidates in development.

Abstract
Nearly half of pregnancies worldwide are unintended mainly due to failure of contraception, resulting in negative effects on women's health. Male contraception techniques, primarily condoms and vasectomy, play a crucial role in birth control, but cannot be both highly effective and reversible at the same time. Herein, an ultrasound (US)-induced self-clearance hydrogel capable of real-time monitoring is utilized for in situ injection into the vas deferens, enabling effective contraception and noninvasive recanalization whenever needed. The hydrogel is composed of (i) sodium alginate (SA) conjugated with reactive oxygen species (ROS)-cleavable thioketal (SA-tK), (ii) titanium dioxide (TiO2), which can generate a specific level of ROS after US treatment, and (iii) calcium chloride (CaCl2), which triggers the formation of the hydrogel. For contraception, the above mixture agents are one-time injected into the vas deferens, which can transform from liquid to hydrogel within 160 s, thereby significantly physically blocking the vas deferens and inhibiting movability of sperm. When fertility is needed, a noninvasive remedial ultrasound can make TiO2 generate ROS, which cleaves SA-tK to destroy the network of the hydrogel. Owing to the recanalization, the refertility rate is restored to 100%. Meanwhile, diagnostic ultrasound (D-US, 22 MHz) can monitor the occlusion and recanalization process in real-time. In summary, the proposed hydrogel contraception can be a reliable, safe, and reversible male contraceptive strategy that addresses an unmet need for men to control their fertility.

Abstract
OBJECTIVE The objective of the study was to evaluate college students' perceptions and behavioral intentions related to a new long-acting reversible contraceptive (LARC) for people with penises: non-hormonal intravas injectable gel (NH-IVIG). DESIGN AND SAMPLE Data collection utilized predictive constructs from the theory of planned behavior. An online questionnaire surveyed undergraduates (ages 18-24 years) at a Midwestern, liberal arts college (N = 460). RESULTS Of potential NH-IVIG users, 28.6% of males and 51.4% of females reported being overall likely to use or encourage its usage. The top three hypothetical NH-IVIG promoters were low cost, reversibility, and infrequent administration. High cost, new product uncertainties, plus administration via injection for the males, were the most frequently cited NH-IVIG deterrents. A majority of potential users indicated intentions to use protective barriers or other contraceptives simultaneously with NH-IVIG; females were more likely overall. Most respondents (males, 90.4%; females, 98.5%) agreed all sexual partners should be equally responsible for contraception. Over half trusted both males and females to use contraception, but females were significantly more trusted and trusting. CONCLUSION Understanding factors influencing NH-IVIG usage can direct initiatives for sperm-targeted LARCs to mitigate risk behaviors and optimize public health promotion.

Abstract
State-of-the-art applications of nanomedicine have the potential to revolutionize the diagnosis, prevention, and treatment of a range of conditions and diseases affecting women’s health. In this review, we provide a synopsis of potential applications of nanomedicine in some of the most dominant fields of women’s health: mental health, sexual health, reproductive medicine, oncology, menopause-related conditions and dementia. We explore published studies arising from in vitro and in vivo experiments, and clinical trials where available, to reveal novel and highly promising therapeutic applications of nanomedicine in these fields. For the first time, we summarize the growing body of evidence relating to the use of nanomaterials as experimental tools for the detection, prevention, and treatment of significant diseases and conditions across the life course of a cisgender woman, from puberty to menopause; revealing the far-reaching and desirable theoretical impact of nanomedicine across different medical disciplines. We also present an overview of potential concerns regarding the therapeutic applications of nanomedicine and the factors currently restricting the growth of applied nanomedicine.

Abstract
Nanocarrier mediated targeted delivery and biosensing in reproductive health care is a major exploratory domain. This work demonstrates the loading of silver nanoparticle (AgNP) inside the multiwalled carbon nanotube (MWCNT) and their targetability to the intracellular part of the sperm cell for its further application in biosensing based infertility diagnosis. Ocimum tenuiflorum (tulsi extract) mediated photosynthesized AgNP exhibited spherical shape, 5-40 nm size and surface plasmonic resonance at 430 nm. After loading of freshly prepared AgNP into emulsified MWCNT, the loading was confirmed with spectroscopic and microscopic methods. FTIR analysis displayed significant shifting at 3450 cm-1 (-OH stretching) and 1615 cm-1 (CNT back bone) which validated the binding of AgNP with MWCNT and interestingly heat flow analysis revealed that Ag loaded MWCNT has greater stability than AgNP. Moreover, AFM based surface profile height analysis clearly showed the loading of AgNP inside MWCNT as surface height of MWCNT increased from 22 to 32 nm, which in turn confirmed the encapsulation of 10 nm size of AgNP inside the tube. Furthermore, surface enhanced Raman spectroscopy (SERS) confirmed the homogeneous loading as there were no changes in D/G ratio. SERS analysis for the interaction of AgNP loaded MWCNT with freshly collected healthy, motile human spermatozoa showed a significant Raman shift at 800-780 cm-1 (NH2+ twist) and 1050-1060 cm-1 (vas PO3-) for change in DNA packaging process and its stabilizing protein polyamine respectively. Finally, DNA fragmentation and morphological examination confirmed the binding and targetability of AgNP to the sperm nucleus. Improved targeting efficiency and biosenssing ability make AgNP-MWCNT composite suitable in fertility diagnosis.

Abstract
Over the last two decades RISUG has been drawing attention in the field of male contraception. It promises to sterile men for a period of up to 10-15 years. According to recent studies in animal models, it proves to be completely reversible. Practically, there are no better options available that can assure complete sterility and precise reversibility. Regardless of so much of information available, RISUG is still holding up for many reasons, firstly, the available information engender bewilderment such as what is this copolymer, how does it work and is reversal really possible? Secondly, advancement of this outstanding invention is drastically slow and thirdly, effects of long-term contraception with RISUG and reports on evaluation of anomalies (if any) in F 1 , F 2 progenies, are lacking. In this review the lacunae as well as advances in the development of RISUG in the light of published work and available resources are pointed out. Formulation of the RISUG, its mode of action and clinical trials have been addressed with particular emphasis.

Abstract
The world's population is nearing 6.8 billion, and we are in need of a male contraceptive that is safe, effective, reversible and affordable. Hormonal approaches, which employ different formulations of testosterone administered in combination with other hormones, have shown considerable promise in clinical trials, and they are currently at the forefront of research and development. However, the long-term effects of using hormones throughout a male's reproductive life for contraception are unknown, and it may take decades before this information becomes available. Because of this, many investigators are aiming to bring a nonhormonal male contraceptive to the consumer market. Indeed, there are several distinct but feasible avenues in which fertility can be regulated without affecting the hypothalamus-pituitary-testis axis. In this review, we discuss several approaches for fertility control involving the testis that one day may lead to the development of a nonhormonal male contraceptive.
