Infertility affects one in six couples, but it’s still something of a taboo subject. Gareth Farr’s new play throws welcome light on the challenges of conception, and is accompanied by a Fertility Fest that brings together artists and medical experts to address the issues raised. If Farr’s drama occasionally feels like a case study for that discussion, with a few awkward sitcom beats tossed in, it’s still a searingly honest and genuinely affecting piece of work.

Satire, we’re solemnly instructed in Dougal Irvine’s new musical The Busker's Opera, “has to strike a fine balance of entertainment and teaching”. Well yes, but it’s also generally wise (discretion, valour, and all that) to keep the theatrical crib sheet to yourself, just in case your product doesn’t quite measure up. This latest show from the award-winning composer and lyricist of Departure Lounge and Britain’s Got Bhangra leads with its chin, and despite energy and bags of insouciant confidence, can’t quite pull off the pose.

Theatregoers suffering from First World War fatigue may want to pass on Jonathan Lynn’s merely competent historical drama about two mythic figures: Charles de Gaulle and Philippe Pétain. It’s a fascinating subject – de Gaulle had his former mentor tried for treason in 1945 after Pétain led France into Nazi collaboration – but Yes Minister co-creator Lynn, who also directs, seems unsure whether it warrants winking satire or solemn historical re-enactment, settling for a fitfully engaging hybrid.

It is a nightmare scenario: you have an accident that leaves you comatose. You are out of action in hospital for three weeks and then, when you wake up, you gradually realise that you don’t remember anything of the past 10 years. Not three weeks, but 10 years! So what has happened to your life? This is the basic premise of Olivier- and Tony-award-nominee Peter Quilter’s new drama, 4000 Days, whose title aptly describes the gap in the experience of its protagonist, played by the ever-watchable Alistair McGowan.

After 12 seemingly idyllic years, Tom and Beth’s marriage is over. That’s a concern for Gabe and Karen, partly because they care for their friends, and there’s the ugly business of choosing sides, but mainly because it causes them to call into question their own previously impervious union. In Donald Margulies’s ruminative 2000 Pulitzer Prize-winner, solipsism rules.

Stop press: our rampant celebrity culture might not be wholly positive! If you’ve already been apprised of that fact some time in the past century, go ahead and skip actor Daniel Dingsdale’s debut play, which – along with Steve Thompson’s similarly outmoded Roaring Trade in the main house – stifles the often creatively programmed Park Theatre’s claim to relevance.

If you were expecting a fusty, formal adaptation of Anthony Trollope – and one of his least known novels, to boot – Lady Anna: All At Sea will come as a breath of fresh air. Colin Blumenau’s production of Craig Baxter’s play, based loosely around the Trollope novel of the same name and commissioned by the Trollope Society to mark the bicentenary of the writer’s birth, speeds through its two-hour-plus run, keeping a nimble crew of seven on its toes and the audience engaged in its ludic conspiracies.

The Israeli-Palestinian conflict has not been very prominent in the news recently, but that doesn’t mean that it has gone away. As Julia Pascal’s 2003 play reminds us, religious and cultural tensions can go deep. Very deep. At the centre of her intense story, which is set over about 24 hours during the second intifada, is Jerusalem, a divided city, a contested territory, a place which is dangerous to cross. As bombs explode in cafés and on buses, the events of the drama illustrate the tight embrace of the personal and the political.

Families. Whether it's the House of Atreus, the court at Elsinore or the Archers, they tend to be of compelling interest. For most of us, loyalties, guilty secrets, truths that will out, petty jealousies and sentimentality tend to be the order of the day more often than towering passion and murder. And that is what Andrew Keatley focuses on in this gentle, poignant, often funny play about a family reunion in the run-up to the "things can only get better" election in 1997.

Seldom has there been such impassioned debate about whether a play has a right to exist. Writer Jonathan Maitland faced a barrage of criticism, with many accusing him of exploitation; others felt it was too soon for freshly unveiled horror to re-emerge on stage. Lead actor Alistair McGowan disagreed, noting Savile’s victims feel the telling of this tale comes “30 years too late”.
