A recent study has found that sperm deteriorates over time as it remains in the body, leading researchers to suggest that men who ejaculate more frequently may have better sperm quality.The study, which combined 115 human studies involving nearly 55,000 men and 56 studies on non-human species, found that the longer men went without sex, the more their sperm showed signs of DNA damage and oxidative stress, and the more tests rated the sperm as less viable and poorer swimmers.The World Health Organization (WHO) recommends men abstain from ejaculating for two to seven days before giving sperm for fertility tests or IVF, but the guidelines were designed to obtain the highest sperm count rather than prioritizing the best quality sperm.Dr. Krish Sanghvi, lead author of the study, said: "In men, the negative effects we found on sperm DNA damage and oxidative damage were large-ish, so we are confident that this is a biologically meaningful and important effect."The study's findings suggest that clinicians and couples should reconsider whether long abstinence is always good, as abstinence leads to deterioration in sperm quality.For couples trying to conceive naturally, a balance between quantity and quality needs to be struck, with abstaining for too long or too little potentially affecting sperm quality and quantity.Experts say that for assisted reproductive technology (ART) treatments, it's having the freshest, most healthy sperm that is probably more important, and that the two to seven days abstinence rule may not be as crucial when IVF treatment is taking place.

The Financial Conduct Authority (FCA) has accused Crispin Odey, a former hedge fund manager, of attempting to manipulate a victim of sexual assault into silence. According to evidence presented in court, Odey sent a text to his former employee in January 2022, warning her that the FCA could question her about him.Odey, who has previously accepted that he groped the woman without her consent in 2005, claimed he was under the influence of sedatives at the time. He now faces a number of sexual harassment allegations and has launched a £79m libel lawsuit against the Financial Times.The FCA's lawyer, Clare Sibson, argued that Odey was trying to manipulate the victim into silence and had a clear motive to discourage her from providing her account to the FCA. Odey, however, claimed he only wanted to ensure the woman would "tell the truth".The hearing continues, with Odey hoping to overturn the FCA's decision to ban him from the UK's financial services industry. In addition to the libel lawsuit, Odey is also facing civil personal injury claims by five women, including one who accused him of rape.

The traditional cold war diplomacy of brinkmanship, characterized by carefully balanced standoffs and rules-based international order, has given way to a world in freefall. This shift is exemplified by the ever-widening conflict in the Gulf where strategic objectives remain as unclear as the potential endpoint of hostilities.Approaching a month since the United States and Israel launched attacks on Iran, the stated objectives of removing the country's nuclear threat and destroying its ballistic missile capability appear increasingly disconnected from the disproportionate impact on civilians and neighboring Gulf nations. Despite these consequences, the Iranian regime's willingness to escalate the conflict shows no signs of diminishing.The Guardian Weekly's coverage examines this critical juncture through multiple perspectives. Patrick Wintour recounts the pivotal week when global tensions reached a tipping point, while Richard Partington analyzes the long-term economic implications of a prolonged conflict, from oil price fluctuations to inflationary pressures and economic growth impacts. From South Lebanon, William Christou reports on healthcare professionals caught in the crossfire of Israeli airstrikes, highlighting the human cost of the escalating violence.Emma Graham-Harrison provides insight from Jerusalem, examining Israeli Prime Minister Benjamin Netanyahu's strategy of attempting to rehabilitate his image through what he frames as destruction of an 'axis of evil.' Meanwhile, Simon Tisdall poses a critical question: when US President Donald Trump eventually seeks to halt the conflict, will any parties be willing to heed his calls for de-escalation?Beyond the primary geopolitical focus, this week's Guardian Weekly edition explores several significant developments across different sectors. The UK political landscape features an examination of the upcoming local elections, where voter sentiment appears increasingly focused on rejecting established parties rather than actively supporting alternatives. The scientific section explores innovative approaches to addressing snoring disorders through CPAP machines, while the culture section features an in-depth interview with Dave Grohl discussing Foo Fighters, personal challenges, and grief following the loss of bandmate Taylor Hawkins.In sports, the publication celebrates the remarkable achievement of British athletes Keely Hodgkinson, Georgia Hunter Bell, and Molly Caudery, who each secured gold medals at the world indoor athletics championships in Poland, showcasing British excellence in track and field events.

Europe is bracing for a potential energy crisis, with fuel rationing possible as early as April if the Strait of Hormuz, a critical passage for oil and gas supplies, remains closed. Shell's CEO, Wael Sawan, issued this stark warning at a major oil industry conference in Texas, highlighting the escalating risks to global energy supplies.The crisis, now in its fourth week, has already led to energy rationing in Asian countries and significant price hikes for jet fuel, which has doubled in price since the start of the conflict. Sawan predicts that diesel and petrol will come under pressure next, particularly as the summer driving season begins in the US and Europe.Oil prices have fluctuated, dipping back to about $100 a barrel on Wednesday after reaching highs of around $114 earlier in the week. These developments have raised concerns about the potential for a prolonged global economic recession if oil prices continue to rise, with some predictions suggesting they could hit $150 a barrel.Larry Fink, CEO of BlackRock, the world's largest asset manager, warned of profound implications for the world economy if the conflict continues to drive up oil prices. He outlined two possible scenarios: one where the conflict resolves quickly, allowing oil prices to return to pre-crisis levels of about $70 a barrel, and another where prices remain high for years, potentially leading to a stark and steep recession.Germany's economy minister, Katherina Reiche, also spoke at the conference, cautioning that energy supply scarcity could occur in late April or May if the conflict continues. She criticized Germany's decision to phase out nuclear energy and emphasized the need for greater imports of gas via super-chilled tankers from overseas.

A newly expanded policy from the Trump administration could require travelers from five World Cup-qualified African countries to post a bond of up to $15,000 in order to enter the United States for the tournament.Visa bonds function as security deposits: a one-time payment that is meant to be refunded after a traveler exits the US under the terms of their visa. The amounts typically range between $5,000 and $15,000, and are required for passport holders from certain countries to enter the US legally under B-1 or B-2 visas, which are necessary for business travelers or tourists.The US State Department has mandated these bonds since launching a pilot program in late 2025, targeting many of the same countries affected by the Trump travel ban along with others – predominantly nations from Africa, the Middle East, Latin America and parts of Asia. Last week, the state department announced an expansion of the program, with visitors from 50 countries now required to submit the deposits if requested by US consular officials.Among those 50 countries, five have qualified for the World Cup, all from Africa: Algeria, Cape Verde, Côte d'Ivoire, Senegal and Tunisia. Though refundable, the cost of the bonds alone is sufficient to make travel to the US prohibitively expensive for most fans from these nations, where average annual income levels are approximately $5,000 per year or less. Tunisia is scheduled to play one group-stage game in the US with the other two in Mexico. Senegal and Côte d'Ivoire will play twice in the US and once in Canada. Algeria and Cape Verde will compete in all three of their group-stage matches in Mexico.Even if affordable for some supporters, the multi-thousand dollar requirement adds another significant complication for fans from these countries, including exorbitant ticket prices for the games themselves, hotel rates far above average, plus additional visa processing delays and potential safety concerns created by the presence of federal immigration officers from ICE and other agencies in US cities.It remains unclear which entities, if any, will be exempt from the visa bonds. While Trump's travel bans contain exemptions for athletes and officials participating in major sporting events like the World Cup, the visa bonds program contains no such provision.The 2026 World Cup is scheduled to commence on June 11, with the final taking place on July 19 at MetLife Stadium in East Rutherford, New Jersey.

The ongoing conflict led by the US has sparked intense debate globally, with many urging for an immediate cessation of hostilities. The war's continuation poses significant humanitarian and geopolitical risks.Experts and analysts stress that prolonged conflict could lead to escalating tensions and unpredictable outcomes. The situation demands a diplomatic solution to prevent further destabilization.The call for peace comes as global leaders seek to address the crisis through negotiations. The US must weigh its strategic objectives against the human cost and consider the long-term implications of continued military action.

Iran has announced the appointment of Mohammad Bagher Zolghadr as the new secretary of the Supreme National Security Council, a move seen as a significant development in the country's security landscape. The appointment comes on the heels of a recent missile strike on Tel Aviv, which resulted in major building damage and at least four casualties. Iranian missiles created impacts in several areas of the city, escalating tensions between Iran and Israel. The new security chief, Zolghadr, will be tasked with navigating these complex geopolitical dynamics and ensuring the country's security interests are protected.

The escalating geopolitical tensions in the Middle East are creating substantial uncertainty for energy markets across Asia, with analysts increasingly concerned about potential supply chain disruptions that could trigger widespread energy shortages.Regional instability in the Middle East has traditionally had far-reaching consequences for global energy markets, given the region's status as a primary source of oil and natural gas exports. Asian nations, which are among the world's largest energy importers, are particularly vulnerable to any disruptions in supply routes or production facilities.Energy security experts warn that prolonged conflict could lead to significant price volatility and potential shortages, particularly affecting countries with heavy industrial sectors and rapidly growing energy demands. The situation underscores the delicate balance between geopolitical stability and economic prosperity in the region.
