Does Poletet Shichvat Zera Apply to Artificial Insemination?

May 3rd, 2026|Niddah, Sex, Yoreh De'ah|

QUESTION

What would you say about a couple who have to do artificial insemination (such as IUI) while the woman is in niddah? Would poletet shivchat zera apply such that they would have to delay mikvah by four days?

ANSWER

Thank you for your question; it’s a really good one. My immediate intuition was that poletet should not apply here, for a few reasons.

By way of introduction, the concept of poletet shichvat zera is the basis for the common practice of waiting a minimum of four or five days before beginning the shivah

Does Zoom Solve Yichud Problems?

January 10th, 2021|Even HaEzer, Sex|

QUESTION

New York, NY

Does the Rosh HaYeshivah hold that a person occasionally glancing at an unmarried couple through a zoom video call could be considered a shomer/et for purposes of yichud? If so, does internet quality matter?

ANSWER

Assuming that the couple is in view, definitely. See Iggrot Moshe EH 4:65.2 – who speaks about being aware that something is going on, even if not directly seeing,

Guided Questions for Chavruta Learning

  1. Sources 1-7 were covered in the previous sheet.  Look at sources 8-12.  Do they indicate that a fetus has the legal status / protections of a human life or not?  Which ones indicate yes, which ones indicate no?  If one were to claim that it was a life, how would she reconcile all the sources?  How would one do so if she were to claim that it was not a life?  Is there a middle position?  How would you articulate it: quasi, potential, or something else?  What halakhic category would destroying such a

Yichud in a Shul

July 26th, 2016|Sex|

Question:

לגרסה העברית לחצו כאן / Read this teshuva in Hebrew

I am the rabbi of a shul, and recently I was working there after it had already grown dark outside. I realized only later that there were two women working in the shul office on a different floor at the same time. To avoid yichud, I thought that she could lock her door and I could lock mine, but realized as I have a master key that wasn’t much use. One woman is married and the other is single. There are cameras in the building

Public Displays of Affection

July 26th, 2016|Niddah, Sex, Tzeniut|

Question:

לגרסה העברית לחצו כאן /Read this teshuva in Hebrew

I am a kallah teacher and was asked if I have any halakhic or rabbinic sources about public displays of affection—from simply holding hands to hugging and kissing in public. The woman also considered that the guidelines might be different in front of intimate family rather than in a large public space, such as at a wedding, etc. The husband is leaning towards a more stringent approach, but she wants “to do the right thing, not just the stricter thing.” She wants real answers rooted in sources that

Question:

לגרסה העברית לחצו כאן /Read this teshuva in Hebrew

I am currently sitting shiva for my mother a”h. I am also currently in niddah and my mikveh night would be tomorrow night. I know that during shiva I’m not allowed to have sex with my husband but I wanted to know if I could go to the mikveh so that we can hug and touch, at least in a non-sexual way. I could really use a hug from my husband and his reassuring touch during this time. Would we also be allowed to sleep in the same bed?

Answer:

Thank you for your question. I am sorry to hear of

Levels of Obligation in Shemirat Negiah

July 22nd, 2015|Marriage and Family, Niddah, Sex, Yoreh De'ah|

QUESTION

What is the origin of our current expectation of extra marital shemirat negiah (abstaining from touch)? Is this truly a halakhic obligation?

ANSWER

Thank you for the question. The first thing to note is that not all forms of touch are the same. There is casual, non-sexual touch; there is intimate, and yet non-sexual touch; and there is sexual touch. Even within sexual touch, there is touch that is very proximate to the act of intercourse, and touch that, while sexual, is more distant from the act of intercourse. Halakha in general does not lump all acts along a spectrum into the same

ANSWER

Let me start by saying how my heart goes out to you

Condoms in Halakha

July 20th, 2015|Marriage and Family, Sex|

QUESTION

Is a condom ever permitted according to Halakha?

ANSWER

First, please note than an extensive presentation of the relevant sources on both sides of the issue, can be found in my source packet on birth control (in particular, the teshuvot of Rav Moshe, sources 41-44).

To respond briefly here – It is generally understood by the larger community that condoms are always forbidden. Amongst the poskim also, the dominant, although not unanimous, voice is that barring life-threatening situations (for example, a doctor who was poked by a dirty needle and is waiting for the results from an AIDS test,

Separating on Marriage Night (Dam Betulim)

July 20th, 2015|Marriage and Family, Niddah, Sex, Yoreh De'ah|

QUESTION

If a couple has sex the night of their wedding do they need separate immediately following intercourse? It feels like a punishment for couples who actually wait, not even being able to enjoy the a full night together and then separating for at least 12 days.

ANSWER

If the woman is a virgin and her hymen is not perforated then after the first act of vaginal intercourse, she and her husband have to separate. This is the principle of דם בתולים, that the first hymeneal bleeding, in the Talmudic and Geonic period, was treated as menstrual bleeding. This practice even grew to
