Grimsby MP Austin Mitchell, has claimed his party is being weakened by growing numbers of women.
He wrote in the Daily Mail at the weekend that more female MPs would make the Commons "less exciting" and preoccupied with "family issues" and "small problems rather than big ideas".
"Whatever the state of Labour's policies for the next election, there is little doubt that it will be fought by a younger, more attractive body of candidates," he said.
"The parliamentary party is undergoing the biggest process of feminisation and rejuvenation embarked on since fabulous pink Camay soap promised to make us look a little lovelier each day."
The 79-year-old - who announced in April that he would not be standing for the next general election - claimed ageism was "rampant" in the Labour Party and that many MPs over 60 were being pressured to stand down.
Many former MPs are being shifted into the House of Lords which left Mr Mitchell declaring it a "marvellous political retirement home".
Mr Mitchell claimed the rise of women would "feminise" party policies.
"Our new preoccupations will be social, educational and family issues, all brought to the fore by the feminisation of Labour through the obsession with all-women shortlists."
He later went on to call the lists a "suspension of party democracy".
Mr Mitchell added: "It cannot be denied that feminisation and youthification will make Parliament brighter, smarter and nicer.
"Yet the Commons will also be more preoccupied with the local rather than the international (not necessarily a bad thing) and small problems rather than big ideas and issues (a very bad thing as it will be less exciting and lead to sixth-form essays read out word for cut-and-pasted word, replacing oratory).
"The Left will be even smaller but the party more manageable and reasonable, for apart from obsessive feminism, women MPs are more amenable and leadable and less objectionable.
"But it might not make us tougher."
