Doctor Who has seen a dip in ratings since the series, which stars Jodie Whittaker as the first female incarnation of the Time Lord, began in October.

The iconic sci-fi show is now on its fifth episode, and Sunday night's episode The Tsuranaga Conundrum, which received an average of 6.1 million viewers.

In comparison, the season's first outing The Woman Who Fell To Earth had 8.2 million watching, almost double the viewer ratings for last year's opener.

Dip: Doctor Who ratings have dropped to 6.1 million viewers for latest episode after a series high of 8.2 million for the opener... as some viewers branded the show 'too PC'

The most recent episode saw a man give birth in space as the Doctor and her companions dealt with the threat of an adorable yet dangerous alien.

So far, 5.9million viewers have been calculated to have watched the episode, although this figure will rise when the 28 day consolidated figures are calculated and iPlayer viewers are included.

Arachnids In The UK and Rosa, the series' third and fourth episodes respectively, received an average of 6.4 million, while the second episode The Ghost Monument had a total of 7.1 million tuning in.

With Chris Chibnall at the helm of the eleventh series, so far the Doctor has got her TARDIS back, fought spiders, and met civil rights icon Rosa Parks in Alabama in 1955.

Some viewers complained that the reason why they no longer wanted to watch the show is because it was too 'PC' for their liking, as one wrote on Twitter: 'This show has become so PC ive actually stopped watching. And 99% of my friends and family have aswell. (sic)'

Another said: 'Well after years of watching #DoctorWho this new series has put the nail in the coffin for the time being. Capaldis last season was bad enough but this is now pure PC boring tripe nowadays. I honestly wish they cast Bradley Walsh as the doctor. He'd have been great!'

But others suggested that it was the series' writing that was the problem as another user complained: 'Just caught up on Dr Who episode 4. I love #JodieWhittaker as the Dr. I even like the 3 side kicks instead of one. I can just about stomach the constant PC agenda, but what i can't stand is the lazy, dumbed down writing under #chibnall (sic)'

Other Doctor Who fans hit back those criticising the show for being too 'PC' as one said in a detailed tweet: 'A woman giving birth to kittens, a male horse named Susan, a lesbian lizard, a bitchy trampoline, a giant pregnant telepathic face...

'I could go on, but there's a character limit. This isn't the strangest or most PC thing in the show and it's perfectly in the spirit of the show.'

One said: 'Love the people furious and claiming a show to be 'too PC' because in a fictional 67th Century, a male alien gave birth,' before adding a facepalm emoji.

While one user aptly said: 'Shaking my head over the people who are moaning that "Doctor Who is getting too lefty PC woke etc" because of the pregnant man storyline. #DoctorWho has always been about wonder and joy at difference. If you missed that, you weren't watching it right.'

For the whole of Doctor Who's Modern Era, each season has seen a drop in ratings as they've progressed, while Christmas specials have provided many highs.

During Christopher Ecclestone's run as the Ninth Doctor, the series opener had an average of 10.81 million watching, but by the finale -where he also regenerated- 6.91 million tuned in, just shy of the series' low of 6.81 million for Bad Wolf.

The ratings also fluctuated throughout David Tennant's stint as the Tenth Doctor, where his first episode got 9.84 million, while he had a series high of 13.31 million for Voyage Of The Damned, and a low of 6.08 million for The Satan Pit.

While in Matt Smith's first season as the Eleventh Doctor the opener got 10.09 million viewers tuning in, but the ratings plummeted -much like the current season- to an average of 6.70 million for the finale.

Peter Capaldi's outing as the Twelfth had the lowest ratings for the show, by far, as his final season averaged 5.5 million viewers overall, with a high of 6.68 million viewers, and a low of 4.73 million.
