Elon Musk wants more kids through surrogacy, says report: What do you need to know about sperm donation?
Upto what age can men donate sperm?
'Sperm donation in India is safe, well-regulated, and quite simple when done through the right channels. The law allows men between 21 and 55 years to donate sperm. Since sperm quality starts to dip with age, the aim is always to get the healthiest sperm,' says Dr Muskaan Chhabra, Birla Fertility & IVF, Delhi.
However, a majority of sperm banks would like donors under the age of 35. 'Sperm quality tends to deteriorate after 40 in terms of quantity, motility and DNA quality. On the other hand, men can, in theory, father children at even older ages, but assisted reproduction and conception chances might go down with advancing age,' says Dr Mannan Gupta, HOD, Obstetrics, Gynaecology & IVF Expert at Elantis Healthcare, Delhi.
Older men can have decreased sperm count, movement and shape, all of which impact fertility. 'Moreover, sperm DNA fragmentation increases, which can impact embryo development and raise the risk of miscarriage,' adds Dr Gupta.
What are factors to keep in mind before becoming a donor?
Sperm donors undergo a complete medical history examination to exclude any hereditary or underlying illnesses. 'A series of tests are carried out, which include infectious disease screenings such as HIV, Hepatitis B and C, and Syphilis, as well as genetic carrier testing to detect any concealed conditions,' says Dr Chhabra.
According to her, the parameters are sperm count (at least 16 million per millilitre), motility or the ability of sperms to move efficiently, (a minimum of 42 per cent), and morphology (a minimum of four per cent). Lifestyle plays a significant role as donors have to be non-smokers, not have used any drugs and be in top physical condition.
How is the donor sperm stored?
Sperm samples are frozen and quarantined for a period of 180 days and retested to ensure they're free from infections before use. With modern cryopreservation techniques, sperm can be stored for many years, even decades, without significant declines in quality. 'There have been successful pregnancies using sperm frozen for 10 to 20 years and even longer in some cases. As long as the sample remains frozen without thawing, its quality remains largely unchanged,' says Dr Gupta.
What about the impact on infants?
Dr Gupta says infants born to older fathers might have marginally increased chances of genetic mutations, autism spectrum disorders and schizophrenia. 'The DNA present in the sperm ages along with men, and therefore, the likelihood of transferring genetic abnormalities increases. Still, most infants born to older fathers are completely normal. The overall likelihood of carrying a healthy baby is quite high,' says Dr Gupta.
What are Indian laws?
Sperm donation is governed under the Assisted Reproductive Technology (Regulation) Act, 2021. Only licensed ART banks are allowed to source, screen, store and provide donor sperm. Only a married couple or a single woman can undergo ART procedure and use donor sperm to conceive. To avoid any accidental biological overlap, one donor's sperm can only be used for one intended recipient.

Fuel Fill-Ups in Space? Musk and Bezos Are Working on It
Elon Musk and Jeff Bezos are trying to figure out how to pump gas in space. The billionaire space rivals are working on ambitious missions to the moon or Mars, and a crucial design element for each venture is using spacecraft that take on additional fuel while orbiting Earth. Vehicles that could grab propellants in orbit would be less weighed down at liftoff, letting planners design missions to travel farther from Earth with more cargo, scientific gear or crew members, advocates say. Having depots or in-orbit refueling that give spacecraft something like a truck stop to pull into may sound like science fiction. It is also a concept that engineers have been working on for years. One of the biggest challenges to making it a reality: moving and storing massive amounts of supercold propellants that are prone to boil off in the void of space. Both SpaceX and Blue Origin have much to prove. Some space-industry officials are skeptical that either will have moon landers that depend on orbital fueling ready to meet National Aeronautics and Space Administration timelines. The agency has worked closely with contractors to understand the challenges of in-space refueling, a NASA spokesman says. SpaceX conducted a fuel-transfer demonstration inside a Starship spacecraft during a 2024 test flight and next year is aiming to move propellants between two vehicles. That test has been delayed as the company has faced setbacks with the massive rocket, including an explosion during a ground test in Texas in June. Blue Origin is developing a transporter vehicle that would take on propellant near Earth. Then, it would fly to a lunar orbit, where the transporter would prepare a lander that would take astronauts arriving on a different ship down to the surface of the moon. That mission depends on the company's New Glenn rocket, which the company launched for the first time in January. Engineers have long built rockets and spacecraft to take on all the fuel they need while still on the ground. Those designs have proven their value. They also have their limitations. Take NASA's Apollo missions to the moon. Saturn V, the rocket that sent agency astronauts there, weighed 6.5 million pounds at liftoff, and around 5.5 million of those pounds were fuel. Combined with reusable rockets, fueling in space could make deep-space flights cheaper over time and ease mission logistics, supporters say. 'It has got to be done,' says Dallas Bienhoff, who formerly studied setting up a low-Earth-orbit propellant depot for Boeing and now works for Pasadena, Calif.-based robotic-mining company OffWorld. 'Otherwise, we're going to be limited with what we can achieve in space.' Musk put it this way during a conference talk in 2017. Starship, which then went by a different name, was expected to loft a spacecraft carrying a large amount of mass to low-Earth orbit. The ship wouldn't be able to travel farther without more fuel, he said. 'If you send up tankers, and refill in orbit, you can refill the tanks all the way to the top,' Musk said then. That would allow the ship to continue out to Mars, he added. From Apollo to the present Orbital refueling isn't a new idea. In the early 1960s, NASA officials considered such operations as they tried to figure out how to land astronauts on the lunar surface before the Soviets. The idea didn't go forward then, but it didn't go away. A range of in-space fueling experiments or operations have been conducted over the years, including by Russia. In 2007, the Pentagon's Defense Advanced Research Projects Agency and partners conducted more than a dozen fuel transfers between two satellites. But no U.S. company has put in-space propellant transfers at the center of their deep-space plans as SpaceX and Blue Origin have. Part of the reason is making it all work is difficult. Spacecraft will need to rendezvous in orbit, connect with each other and flow large amounts of propellants from one vehicle to another. The nature of the propellants SpaceX and Blue Origin have proposed using makes transferring them especially tricky. The fuels are chilled to supercold levels to keep them liquid, and have a tendency to boil off. 'It wouldn't be easy to do on Earth. But now you have to do it in space, pumping it from one big refrigerator to another,' says Thomas Cooley, formerly chief scientist for a space-vehicles group at the Air Force Research Laboratory who now has a space-consulting business. Dave Limp, chief executive at Blue Origin, said in a social-media post in July the company had made major progress maturing technologies that aim to prevent propellants from boiling off in space. Fuels also behave in odd ways in space. When you pump gasoline into your car's tank, the gas flows in a predictable manner but that isn't necessarily the case in orbit. There, companies will contend with what William Notardonato, chief executive of Eta Space, calls 'liquid-acquisition issues.' 'You don't know where your liquid is stored. The propellant might be up at the top of the tank. And it brings up the question, what is the top in microgravity?' says Notardonato, whose Rockledge, Fla.-based company is developing an in-space propellant depot and working on a mission where it will track how a supercold propellant behaves in a satellite tank using a camera. Launching, time and again Another unknown for in-orbit refueling: the number of launches it will take SpaceX and Blue Origin to fuel up vehicles for deep-space missions. SpaceX has shown launches can be conducted much more frequently than in the past, but rockets are still a long way from flying as easily as commercial jets. Meanwhile, Starship, the company's vehicle that will use orbital fueling, remains in an experimental phase and Blue Origin is still ramping up New Glenn. During a presentation earlier this year, a Blue Origin executive didn't specify how many refueling flights the company may need for a NASA mission that has it transporting astronauts from lunar orbit to the surface of the moon. For its NASA astronaut moon missions, SpaceX has been planning to conduct multiple launches of a tanker variant of its Starship spacecraft to fuel up a Starship depot in low-Earth orbit, according to NASA officials. Then the company would send a moon-lander Starship to the depot to take on fuel. After that, the lander would fly out to the moon. An executive at SpaceX early last year estimated a moon mission for NASA could take around 10 flights, while a different leader at the company last fall predicted around 16. Some current and former space-industry officials say the number of launches needed may be higher. One former NASA leader during a congressional hearing in February said as many as 20 could be required. A technical paper that has circulated among some industry officials and was viewed by The Wall Street Journal suggests it may take up to 40. Musk, during a recent presentation about SpaceX's plans for Mars, didn't discuss the number of flights that would be needed to send a Starship to the red planet. Staff at the company have talked about trying to send a basic, uncrewed ship out there next year with as few as three refueling flights, the Journal has reported. In a recent post on his social-media site X, Musk said a Starship flight to Mars in 2026 would be tough, giving it just a slight chance of happening.

Today in Politics: Lok Sabha set to discuss Shubhanshu Shukla's space sojourn
The Lok Sabha will hold a special discussion on Monday on the subject 'India's first astronaut aboard the International Space Station – Critical role of the space programme for Viksit Bharat by 2047 – to mark astronaut Shubhanshu Shukla's return to India. Shukla returned to India early Sunday to a rousing welcome by a large number of people waving the tricolour and beating drums at the airport here to celebrate his historic visit to the International Space Station (ISS). The Monsoon Session of Parliament will resume on Monday, 18 August after a brief break, but there are no signs of a thaw between the government and the Opposition over the demand for a debate on Special Intensive Revision (SIR) of electoral rolls. The Monsoon Session ends on 21 August. Shukla is expected to meet Prime Minister Narendra Modi on Monday and travel to his hometown, Lucknow. He is also expected to return to the capital to participate in the National Space Day celebrations on August 22-23. Shukla, who became the second Indian to undertake a spaceflight as part of the Axiom-4 mission, and his back-up astronaut-designate Prashanth Balakrishnan Nair were welcomed at the airport by Union Minister Jitendra Singh, Delhi Chief Minister Rekha Gupta, and ISRO Chairman V Narayanan. Chinese Foreign Minister Wang Yi will meet Prime Minister Narendra Modi during his two-day visit to India beginning Monday, according to the Ministry of External Affairs (MEA). The meeting, to be held on Tuesday, assumes significance as it is taking place days before Modi's planned trip to China to attend the annual summit of the Shanghai Cooperation Organisation (SCO). Before calling on the PM, Wang will hold separate talks with External Affairs Minister S Jaishankar and National Security Advisor Ajit Doval that could see both sides deliberate on a range of key issues including border situation, trade and resumption of flight services. The Chinese foreign minister's visit is largely seen as part of ongoing efforts by the two neighbours to rebuild their relationship after it came under severe strain following the deadly Galwan Valley clashes in 2020. The two sides are expected to discuss new confidence-building measures for durable peace and tranquillity along their contested border during Wang's visit, people familiar with the matter said on Sunday. The Supreme Court is scheduled to hear on Monday a batch of pleas challenging the appointment of Jharkhand DGP Anurag Gupta on grounds that due process was not followed. A bench of Chief Justice BR Gavai and Justices K Vinod Chandran and NV Anjaria is scheduled to hear the petitions challenging Gupta's appointment. Several petitions have been filed, including by Leader of Opposition in Jharkhand Assembly Babulal Marandi, who has challenged the appointment of Gupta as Director General of Police (DGP) of the state. Gupta was set to retire on April 30 under the Central government's rules on reaching the age of 60 but the state government wrote to the Centre for extension of his tenure.

Cong: Tripura's healthcare ‘collapsed' under BJP
Agartala: Criticising the BJP-led govt in Tripura, the opposition Congress alleged the state's healthcare system has 'completely collapsed' even as chief minister Manik Saha is himself a doctor. Congress spokesperson Prabir Chakraborty on Saturday alleged that instead of delivering quality healthcare, the state has witnessed corruption and medical negligence, leading to deaths. Reports from both govt and independent agencies have 'punctured' the much-publicised claim of a 'health revolution', he claimed. According to a recent report by the Union ministry of health and family welfare, Tripura ranked first among northeastern states in malaria and chikungunya cases in 2024-25, despite having only 44 lakh population as compared to Assam's over three crore, Chakraborty said. In 2023, the state recorded 22,412 malaria cases, nearly half of the northeast's total, while chikungunya cases rose from 1,557 in 2023 to 2,452 in Dec 2024, he said. Chakraborty said the report further revealed a disturbing rise in HIV cases. PTI Stay updated with the latest local news from your city on Times of India (TOI).
