Distressing low sexual desire, termed Hypoactive Sexual Desire Disorder (HSDD), affects approximately 10% of women and 8% of men. In women, the 'top-down' theory of HSDD describes hyperactivity in higher-level cognitive brain regions, suppressing lower-level emotional/sexual brain areas. However, it is unknown how this neurofunctional disturbance compares to HSDD in men. To investigate this, we employed task-based functional MRI in 32 women and 32 men with HSDD to measure sexual-brain processing during sexual versus non-sexual videos, as well as psychometric questionnaires to assess sexual desire/arousal. We demonstrate that women had greater activation in higher-level and lower-level brain regions, compared to men. Indeed, women who had greater hypothalamic activation in response to sexual videos, reported higher psychometric scores in the evaluative (r = 0.55, P = 0.001), motivational (r = 0.56, P = 0.003), and physiological (r = 0.57, P = 0.0006) domains of sexual desire and arousal after watching the sexual videos in the scanner. By contrast, no similar correlations were observed in men. Taken together, this is the first direct comparison of the neural correlates of distressing low sexual desire between women and men. The data supports the 'top-down' theory of HSDD in women, whereas in men HSDD appears to be associated with different neurofunctional processes.

Review
INTRODUCTION
Sexual dysfunction is highly prevalent among men of reproductive age. Clinical practice guidelines have been established to assist providers in identification and education of patients who are at increased risk for infertility and sexual dysfunction with certain congenital and acquired urogenital disorders. The authors sought to review the reproductive and sexual health implications of treating common childhood urological conditions with commonly performed surgical procedures.
METHODS
To ensure the inclusion of influential and highly regarded research, we prioritized citations from the most-frequently cited articles on our respective review topics. Our inclusion criteria considered studies with substantial sample sizes and rigorously designed methodologies. Several topics were reviewed, including penile chordee, hypospadias, posterior urethral valves, varicoceles, undescended testicles, and testicular torsion.
RESULTS
For chordee, surgical plication or corporal grafting may be employed. Erectile function remains unaltered post-surgery, while penile length may decrease after repair, which may be avoided using dermal grafts. Hypospadias repair hinges on severity and availability of the urethral plate. Those who underwent hypospadias repair report decreased penile length, but sexual satisfaction, libido, and semen quality are comparable to controls. Posterior urethral valves are usually treated with valve ablation. While valve ablation and bladder neck incision have not been found to affect ejaculatory function, high degree of concurrent renal dysfunction related to nephrogenic and bladder dysfunction may impact semen parameters and erectile function. Regarding varicocele, earlier management has been associated with better long-term fertility outcomes, and surgical intervention is advisable if there is observable testicular atrophy. Earlier repair of undescended testicle with orchiopexy has been found to improve fertility rates as well as decrease malignancy rates. Unilateral orchiectomy for testicular torsion without the ability for salvage has been shown to have decreased semen parameters but unaffected fertility rates.
CONCLUSION
Infertility and sexual dysfunction are multivariable entities, with etiologies both congenital and acquired. At the same time, many common pediatric urology surgeries are performed to correct anatomic pathology that may lead to reproductive dysfunction in adulthood. This review highlights the need for diagnosis and management of pediatric urologic conditions as these conditions may impact long-term sexual function post-operatively.

Background Menopause is a physiological state that occurs in all women and refers to the halt of the reproductive phase. The cessation of the reproductive phase occurs through various stages and presents different symptoms such as hot flashes, night sweats, insomnia, anxiety, depression, and irritability. Such pre- and post-menopausal symptoms may affect the daily activities and production capacities of women, impacting the quality of life (QoL) of women. Hormone replacement therapy (HRT) is primarily used to manage menopausal symptoms. However, various side effects have been reported related to HRT. Therefore, women are choosing alternative medicine such as Ayurveda that can benefit them with less or no adverse effects. Shatavari () is known in Ayurveda as an effective medicinal plant source for various women's health remedies since ancient times. This study aimed to evaluate the safety and efficacy of the Ayurvedic Shatavari formulation on menopausal symptoms compared to the placebo. Methodology This is a randomized, double-blinded, multicenter, placebo-controlled, clinical study. Altogether, 70 patients were randomized to two groups, i.e., the test group (active group) and the placebo group (microcrystalline cellulose), with 35 participants in each group. Results The study outcomes showed a positive and significant effect of the active test ingredient over the placebo in terms of reduction in hot flashes, night sweats, insomnia, anxiety, nervousness, vaginal dryness, and loss of libido. The Utian QoL improved significantly in the test group compared to the placebo group. No significant adverse events were recorded in the test group, suggesting the safety of this formulation. Conclusions The test compound could be a safe alternative to modern drugs. The findings of this study support the traditional use of Shatavari. Further clinical and pharmacological studies with longer duration and larger and more diverse sample sizes are required to understand the generalized effect of Shatavari root extract in menopausal women.

Review
The genus (P. Beauv.) belongs to the Apocynaceae family with over 65 species distributed all over the tropical regions. This genus has a considerable number of documented medicinal, industrial, and ecologically beneficial effects. Therefore, this review is tailored towards the appraisal of the traditional significance, phytochemistry, and pharmacological activities of the genus . This will help researchers understand future research trends by bridging the gaps between documented literature and contemporary uses. Relevant information was obtained from selection of scientific databases such as Web of Science, PubMed, Scopus, Google Scholar, ScienceDirect and Wiley. From documented literature, different parts of have been used to improve fertility, lessen menstrual pain, boost sex libido, cure malaria and typhoid. Several classes of bioactive constituents such as terpenoids, phenolics, flavonoids, steroids, fatty acids, saponins, phytosterol and phenylpropanoid, volatile compounds, lignans and coumarins have been isolated from this genus. These secondary metabolites could be responsible for the reported antimicrobial, antimalarial, aphrodisiac, antioxidant, anti-inflammatory, antidiabetic and anticancer activities exhibited by this genus. The leaves, flower, bark and root of this genus have a wide range of essential nutrients and antinutrients which are essential for normal growth and development in living organisms. Despite all findings indicating the economical, industrial and pharmacological activities of species, secondary metabolites and pharmacological potency of of this genus are not adequately documented. Therefore, bioassay-guided isolation on the extracts with proven biological activities should be prioritised in order to isolate pharmacophores with unique structural frameworks.

Randomized Controlled Trial
Sexual behaviour among women using intramuscular depot medroxyprogesterone acetate, a copper intrauterine device, or a levonorgestrel implant for contraception: Data from the ECHO randomized trial.
BACKGROUND
Contraceptive use has complex effects on sexual behaviour and mood, including those related to reduced concerns about unintended pregnancy, direct hormonal effects and effects on endogenous sex hormones. We set out to obtain robust evidence on the relative effects of three contraceptive methods on sex behaviours, which is important for guiding contraceptive choice and future contraceptive developments.
METHODS
This is a secondary analysis of data from the Evidence for Contraceptive Options and HIV Outcomes (ECHO) randomized trial in which 7,829 HIV-uninfected women from 12 sites in Eswatini, Kenya, South Africa and Zambia seeking contraception were randomly assigned to intramuscular depot-medroxyprogesterone acetate (DMPA-IM), the copper intrauterine device (Cu-IUD) or the levonorgestrel (LNG) implant. Data collected for 12 to 18 months using 3-monthly behavioural questionnaires that relied on recall from the preceding 3 months, were used to estimate relative risk of post-baseline sex behaviours, as well as sexual desire and menstrual bleeding between randomized groups using modified Poisson regression.
RESULTS
We observed small but generally consistent effects wherein DMPA-IM users reported lower prevalence of specified high risk sexual behaviours than implant users than Cu-IUD users (the '>' and '<' symbols indicate statistically significant differences): multiple sex partners 3.6% < 4.8% < 6.2% respectively; new sex partner 3.0% < 4.0% <5.3%; coital acts 16.45, 16.65, 17.12 (DMPA-IM < Cu-IUD); unprotected sex 65% < 68%, 70%; unprotected sex past 7 days 33% <36%, 37%; sex during vaginal bleeding 7.1%, 7.1% < 8.9%; no sex acts 4.1%, 3.8%, 3.4% (DMPA-IM > Cu-IUD); partner has sex with others 10% < 11%, 11%. The one exception was having any sex partner 96.5%, 96.9% < 97.4% (DMPA-IM < Cu-IUD). Decrease in sexual desire was reported by 1.6% > 1.1% >0.5%; amenorrhoea by 49% > 41% >12% and regular menstrual pattern by 26% <35% < 87% respectively.
CONCLUSIONS
These findings suggest that women assigned to DMPA-IM may have a modest decrease in libido and sexual activity relative to the implant, and the implant relative to the Cu-IUD. We found more menstrual disturbance with DMPA-IM than with the implant (and as expected, both more than the Cu-IUD). These findings are important for informing the contraceptive choices of women and policymakers and highlight the need for robust comparison of the effects of other contraceptive methods as well.

Late-onset hypogonadism (LOH) is an age-related disease in men characterized by decreased testosterone levels with symptoms such as decreased libido, erectile dysfunction, and depression. Thymus quinquecostatus Celakovski (TQC) is a plant used as a volatile oil in traditional medicine, and its bioactive compounds have anti-inflammatory potential. Based on this knowledge, the present study aimed to investigate the effects of TQC extract (TE) on LOH in TM3 Leydig cells and in an in vivo aging mouse model. The aqueous extract of T. quinquecostatus Celakovski (12.5, 25, and 50 µg/mL concentrations) was used to measure parameters such as cell viability, testosterone level, body weight, and gene expression, via in vivo studies. Interestingly, TE increased testosterone levels in TM3 cells in a dose-dependent manner without affecting cell viability. Furthermore, TE significantly increased the expression of genes involved in the cytochrome P450 family (Cyp11a1, Cyp17a1, Cyp19a1, and Srd5a2), which regulate testosterone biosynthesis. In aging mouse models, TE increased testosterone levels without affecting body weight and testicular tissue weight tissue of an aging animal group. In addition, the high-dose TE-treated group (50 mg/kg) showed significantly increased expression of the cytochrome p450 enzymes, similar to the in vitro results. Furthermore, HPLC-MS analysis confirmed the presence of caffeic acid and rosmarinic acid as bioactive compounds in TE. Thus, the results obtained in the present study confirmed that TQC and its bioactive compounds can be used for LOH treatment to enhance testosterone production.

INTRODUCTION
The evolution of contraception has been crucial for public health and reproductive well-being. Over the past 60 years, combined oral contraceptives (COCs) have remained an important part of the contraceptive landscape worldwide; continued development has worked toward maintaining efficacy and improving safety.
METHODS
Seven global experts convened to discuss the clinical relevance of the oestrogen in COCs, focusing on the impact of the new oestrogen, oestetrol (E4). Participants then commented through an online forum on the summary content and other participants' feedback. We prepared this report to describe the experts' views, their follow-up from the open forum and the evidence supporting their views.
RESULTS
Ethinylestradiol (EE) and oestradiol (E2) affect receptors similarly whereas E4 has differential effects, especially in the liver and breast. Adequate oestrogen doses in COCs ensure regular bleeding and user acceptability. EE and E4 have longer half-lives than E2; accordingly, COCs with EE and E4 offer more predictable bleeding than those with E2. Oestrogen type and progestin influence VTE risk; E2 poses a lower risk than EE; although promising, E4/DRSP VTE risk is lacking population-based data. COCs alleviate menstrual symptoms, impact mental health, cognition, libido, skin, and bone health.
CONCLUSION
Oestrogens play an important role in the contraceptive efficacy, bleeding patterns, and overall tolerability/safety of COCs. Recent studies exploring E4 combined with DRSP show promising results compared to traditional formulations, but more definitive conclusions await further research.

Many women experience sexual side effects, such as decreased libido, when taking hormonal contraceptives (HCs). However, little is known about the extent to which libido recovers after discontinuing HCs, nor about the timeframe in which recovery is expected to occur. Given that HCs suppress the activities of multiple endogenous hormones that regulate both the ovulatory cycle and women's sexual function, resumption of cycles should predict libido recovery. Here, using a combination of repeated and retrospective measures, we examined changes in sexual desire and partner attraction (among partnered women) across a three-month period in a sample of Natural Cycles users (Survey 1: n = 1596; Survey 2: n = 550) who recently discontinued HCs. We also tested whether changes in these outcomes coincided with resumption of the ovulatory cycle and whether they were associated with additional factors related to HC use (e.g., duration of HC use) or relationship characteristics (e.g., relationship length). Results revealed that both sexual desire and partner attraction, on average, increased across three months after beginning to use Natural Cycles. While the prediction that changes in sexual desire would co-occur with cycle resumption was supported, there was also evidence that libido continued to increase even after cycles resumed. Together, these results offer new insights into relationships between HC discontinuation and women's sexual psychology and lay the groundwork for future research exploring the mechanisms underlying these effects.

BACKGROUND
Biostimulation is a management practice that improves the reproductive parameters, potentiates the desire, and improves the reproductive efficiency during the short breeding season in camels.
AIM
This study aims to investigate the concurrent changes in hormonal profiles in response to management and behavioral situations on camel farms in the Eastern region of Saudi Arabia.
METHODS
A total of 10 male and 50 female camels were used in this study. The hormonal profile of male camels was evaluated weekly starting from December to August.
RESULTS
The results show that both serum testosterone and cortisol levels increased ( < 0.01) from December to March compared to April to August. A strong negative correlation was observed between testosterone levels and temperature ( = -0.81, < 0.05), and a similarly robust negative correlation was found between cortisol levels and temperature ( = -0.83, < 0.05). The dominant rutting males showed higher levels of testosterone than the submissive males. Serum testosterone levels increased ( < 0.01) in males out of rutting after hearing the sounds of other couples before and during mating.
CONCLUSION
Hearing sounds emitted during mating increases the testosterone output, and improves the libido of male camels during the nonrutting period. It is important to keep two individually housed males for mating purposes. One male joins the herd alone in winter (winter rutter), and the other joins in spring (spring rutter), this could keep the libido extended rutting and improve the reproductive performance in camel herds.
