Sperm counts worldwide have been in steady decline for decades, and a group of tech start-ups are finally giving the problem attention.

Manuela Saragosa speaks to the heads of two such companies: Tom Smith of Dadi Inc, which provides home kits for freezing sperm, and Mohamed Taha of Mojo Diagnostics, which is using artificial intelligence to make male fertility testing more reliable. Plus Mylene Yao of Univfy Inc, which focuses on female fertility, says she has noticed a generational shift in her clients' attitudes, with much more focus now on the joint responsibility of men in achieving a pregnancy.

But why is there such a crisis in male fertility in the first place, and what can men do to improve their chances of having a child? Manuela asks Professor Richard Sharpe of the Centre for Reproductive Health at Edinburgh University.

The global construction boom is fuelling an illegal trade in sand used to make concrete, causing environmental degradation and spawning sand mafias in parts of the world. Manuela Saragosa speaks to Prem Mahadevan of the Global Initiative Against Transnational Organised Crime, on what is becoming a global phenomenon. Campaigner Sumaira Abdulali, founder of the Awaaz Foundation NGO in India, recounts how she confronted illegal sand miners who were destroying a stretch of beach she owns south of Mumbai, and John Orr, Cambridge University lecturer in concrete structures, on how we could use less sand in construction.

Is WeWork an exciting new tech firm with lofty ideals worth $47bn, or is it just an over-priced office rental business?

Manuela Saragosa speaks to two sceptics. Rett Wallace of investment advisory firm Triton says the prospectus for WeWork's forthcoming stock market flotation is long on aspirational zen, but rather short on hard financial details. Meanwhile Vijay Govindarajan, business strategy professor at Dartmouth College, is unimpressed by the company's attempt to brand itself as a tech firm.

But plenty of WeWork's tenants are convinced of the value of the service they provide, among them Matt Hubert of software engineers Bitmatica, although he wishes his landlord would cut some of the philosophical waffle and focus on what they are good at.

Can a greater understanding of how poor air quality harms us, enable us to tackle this urgent problem?

How are movie producers making money in the age of online streaming? In Hollywood, if you produce a hit show or blockbuster movie, a cut of the profits can lead to extraordinary wealth. That could mean producers lowering their salaries to get a percentage of the box office. But Netflix and other streaming services don’t play by old Hollywood’s rules.

The BBC’s Regan Morris speaks to executives and producers about how Hollywood’s business model is changing as a content arms race from the streaming services transforms the film industry. She speaks to YouTuber Lizzy Sharer; Producers Guild of America co-presidents Gail Berman and Lucy Fisher; producer Rob Henry; and Disney executive Kevin Mayer.

Is Rwanda's economic success story really all it's cracked up to be?

Why do Americans have to pay so much for this life-saving drug? There are reports of some uninsured diabetics dying as a consequence. Even the health insurers and drug manufacturers say the pricing system is broken.

Manuela Saragosa speaks to Laura Marston, a type-1 diabetes sufferer and campaigner from Washington DC, about how she had to sell her house and leave her hometown just to get access to affordable insulin - and she says she is one of the lucky ones. Meanwhile the US Congress and various state law enforcement agencies are now looking into why the price of insulin is so many times higher in the US than in other developed countries.

So who is to blame? Robert Zirkelbach, executive vice president of the Pharmaceutical Research and Manufacturers of America, represents the drugs companies, while David Merritt, executive vice president of public affairs at America's Health Insurance Plans, represents the insurers.

Is the wealth management industry still too geared towards male clients? And how do women plan their finances in countries where they don't even have an equal right to inherit?

Katie Prescott explores the financial literacy gender gap, and how it is slowly being bridged. She speaks to Natasha Pope, private wealth advisor at Goldman Sachs, who explains how their increasing number of wealthy female clients can take a very different approach to planning their financial futures.

Meanwhile the BBC's Georgia Tolley speaks to women in Dubai about the precarious position many Emirati women find themselves in, as the traditional paternalistic role of men in caring for female family members erodes, yet the law does not yet provide genuine financial equality to both genders.
