Embryo Transfer Into Rabbit: A Procedure for Laparoscopy-Guided Transfer of Embryos Into Oviduct of Ovulating Recipient Female Rabbit Model
0 Views •
2025
This video describes the technique of transferring embryos into the oviduct of a recipient female rabbit via Laparoscopy. It allows embryo remodeling in rabbits during its migration through the oviduct, eventually helping in successful implantation. This technique can also be used for stored embryos with good efficiency.

External Female Genitals

The vulva encompasses the external structures of the female reproductive system. At the forefront is the monpubis, a cushion of fatty tissue atop the pubic bone. Once puberty sets in, this area typically grows hair. Extending from just behind the mons pubis are the labia majora (labia = 'lips'; majora = 'larger'), which are larger skin fs olds coated with hair. Nestled within are the labia minora (labia = 'lips'; minora = 'smaller'), which are thinner, more pigmented, and hairless. While the...
FAQs
Rising estrogen from the developing ovarian follicle provides the hormonal signal that precedes the luteinizing hormone, or LH, surge. This surge changes the follicle’s state, leading to rupture and oocyte release. The sequence links follicular development to ovulation timing and creates a coordinated opportunity for fertilization within the reproductive cycle.
After the LH surge initiates follicular rupture, the released oocyte enters the fallopian tube, while coordinated hormonal feedback supports preparation of the uterine lining. These linked events connect ovarian activity with the broader reproductive cycle, so ovulation is relevant not only to fertilization but also to menstrual timing.
Timing matters because ovulation serves as a reference point linking ovarian activity with menstrual timing and fertility. Understanding when it occurs helps explain patterns in the reproductive cycle and supports interpretation of assessments used for contraception, infertility evaluation, and assisted reproductive treatments. Thus, timing has both biological and practical significance.
Assessment may use cycle tracking, hormone measurements, ultrasound, or a combination of these approaches. Together, they provide ways to examine reproductive timing and ovarian-cycle events without relying on a single type of information. These tools are relevant when researchers or clinicians evaluate fertility, menstrual patterns, contraception, or reproductive treatment needs.
These assessments help clarify reproductive timing and whether ovulatory events fit the expected menstrual cycle. That information can support contraception planning, investigation of infertility, and preparation for assisted reproductive treatments. The approach may involve cycle tracking, hormone measurements, ultrasound, or a combination, depending on the reproductive question being examined.
Because ovulation connects ovarian follicle activity, hormonal signaling, fertility, and menstrual timing, its assessment can place reproductive problems in biological context. Examining the event and its timing may contribute to infertility evaluation and improve understanding of disorders affecting the reproductive cycle, while also informing clinical planning for assisted reproductive treatments.
