Without identifying the speech in question, we can identify a legal trend toward marriage and traditional roles for women between 1936 and 1955.
According to "The Status of Women in the Soviet Union", a long article by Alice Erh-Soon Tay (1972):
IV. The Retreat to "Conservatism"
The crisis [of gender inequality], evident in the late 1920s and continuing into the 1930s, coincided with the rise of Stalin and the concentration on "socialist upbuilding" through the Five-Year Plans. It produced a steady retreat to "conservatism"....Soviet writers began to refer to the family as "a basic unit",... Domesticity was no longer denounced, household work, once described by Lenin as monotonous petty drudgery, was now proclaimed to be "socially useful labor", love of parents, formerly conditional upon their adherence to Soviet values, was elevated as an ethical absolute.
The concern with strengthening the family that becomes so evident from 1936 onward was accompanied by an equally strong concern with increasing the birthrate, greatly intensified---naturally enough---during the Soviet Union's Great Patriotic War, 1941-1945. In 1944 the Presidium of the Supreme Soviet of USSR decreed an increase of State aid to pregnant women, mothers with many children, and unmarried mothers; it strengthened measures for the protection of motherhood and childhood; it established the title "Heroine Mother" and instituted the order "Motherhood Glory" and the "Motherhood Medal". This legislation, embodied in a single Decree, became an act of signal importance that was to dominate Soviet family life until well after the death of Stalin in 1953.
The prohibition on non-therapeutic abortions was repealed in 1955; principal justifications were the large number of abortions performed illegally, outside hospitals and under insanitary conditions, and fidelity to the Leninist doctrine that no woman should be forced to bear a child she did not want.
We read in Russian Law Journal, Vol V 2018 Issue 4, that:
The 18 November 1920 ruling by the People's Commissariats of Health and Justice entitled "On Protection of Women's Health" is a compelling example of reasonable and progressive legislation from the early years of Bolshevik lawmaking.
I. Artificial termination of pregnancy procedures are allowed free of charge in the setting of Soviet hospitals, which guarantees that such procedures are harmless to the maximum extent possible.
The country that pioneered abortion recriminalized abortion in 1936.
So seemingly, there was a period between 1936 and 1955 when abortion was outlawed, and Soviet policy was to encourage a higher birthrate and stable families. Prison was acknowledged as a marriage-breaker, though:
Resolution No. 1945 [29 August 1946 - USSR Council of Ministers] established that if one of the spouses was certified as missing, was missing in action, convicted for a lengthy term of imprisonment (at least three years), or suffered a chronic mental disease, the other spouse had the right to file for divorce directly to the upper court without preliminary consideration of a case in the people's court.
