אמר רבי זירא אמר רבי אבהו ואמרי לה במתניתא תנא עשרה דברים נאמרו בכוס של ברכה … ויש אומרים אף משגרו במתנה לאנשי ביתו
Rabbi Zeira said that Rabbi Abbahu said, and some say that this halakha was taught in a baraita: Ten things were said with regard to a cup of blessing, e.g., the cup of wine over which Grace after Meals is recited: … And some say: He also sends it as a gift to members of his household.
ומשגרו לאנשי ביתו במתנה כי היכי דתתברך דביתהו
And he sends it as a gift to members of his household; so that his wife will be blessed.
עולא אקלע לבי רב נחמן כריך ריפתא בריך ברכת מזונא יהב ליה כסא דברכתא לרב נחמן אמר ליה רב נחמן לישדר מר כסא דברכתא לילתא אמר ליה הכי אמר רבי יוחנן אין פרי בטנה של אשה מתברך אלא מפרי בטנו של איש שנאמר וברך פרי בטנך פרי בטנה לא נאמר אלא פרי בטנך…
The Gemara relates: Ulla happened to come to the house of Rav Naḥman. He ate bread, recited Grace after Meals, and gave the cup of blessing to Rav Naḥman. Rav Naḥman said to him: Master, please send the cup of blessing to Yalta, my wife. Ulla responded to him: There is no need, as Rabbi Yoḥanan said as follows: The fruit of a woman’s body is blessed only from the fruit of a man’s body, as it is stated: “And He will love you, and bless you, and make you numerous, and He will bless the fruit of your body” (Deuteronomy 7:13). The Gemara infers: “He will bless the fruit of her body” was not stated. Rather, “He will bless the fruit of your [masculine singular] body.” For his wife to be blessed with children, it is sufficient to give the cup to Rav Naḥman. …
The Gemara relates that meanwhile Yalta heard Ulla’s refusal to send her the cup of blessing. [Yalta was the daughter of the Exilarch and was accustomed to being treated with deference,] so she arose in a rage, entered the wine-storage, and broke four hundred barrels of wine. Afterward, Rav Naḥman said to Ulla: Let the Master send her another cup. Ulla sent Yalta a different cup with a message saying that all of the wine in this barrel is wine of blessing; although you did not drink from the cup of blessing itself, you may at least drink from the barrel from which the cup of blessing was poured. She sent him a stinging response: From itinerant peddlers, Ulla traveled regularly from Eretz Yisrael to Babylonia and back, come meaningless words, and from rags come lice.
